HPR-PL-1(31)ltem273 Q U A U N ASSURANCE PROGRAM FOR MATERIALSTESTING METHODS AND PROCEDURES PROBLEM STATEMENT The Artzona Department of Transportation is updating its Quality Assurance Program In order to meet the requirements of FHWA Federal-Aid Highway Program Manual (WPM); Volume 6, Engineering and Traffic Operations; Chapter 4, Construction and Maintenance; Sectlon2, Construction; Subsecffon 7, Sampllng and Testlng of Materials and Construction; dated January 22, 1987. FHPM 6-4-2-7 estaMishes general requirements for the sampling and testing of materials and construction on Federalaid hlghway projects. Three major rwlslons to the previous manual deal with the Letter of Certification. The letter now states: 1. The resutts of the tests on acceptance samples fndlcste....were In conformity with the approved plans The previous statement was 'reasonabty close' conformrty.... 2. The results of sampling and testing for acceptance compare favorably with the resut!s of the independent assurance sampling and teating. This statement implies that an independent assurance sampling and testing program is functioning as intended; however, what do the results of the Independent assurance tests really mean In regard to acceptance and overall quality of the rnaterjals incorporated Into the project? 3. Exceptions to the plans and speciflcationr are explained on the back or an attached sheet An exception is considered to be any material represented by an acceptance test that is shown to not meet the criteria contained in the plans and speciffcations .... Per FHPM 64-27,the frequency for independent assurance tests should be approximately 10 percent of the frequency of the acceptance tests. ADOTs acceptance test criterh (induding the Sampling Guide Schedde maintained by the Materials Section) has been approved by the M W A Additionally, approval has been granted to ADOT to allow a 2.5 percent frequency rate for lndependent assurance samples versus acceptance samples. FHPM 64-2-7 states the resul!s of the independent assurance samples and test are used for the purpose of making independent checks on the reliability of the results obtained in acceptance sampling and testing and not for determining the quality and acceptability of the material and workmanship directly. The question then becomes, what is an acceptable independent assurance test result in relation to the acceptance criteria? Is there a range for the Independent assurance test, or is it simply pass or fad. based on the statistical framework of the acceptance test program? If there is a range, what should it be? In Federal Reafster, Vd. 51, No. 216. November 7, 1986, p. 40416, a comment was made in regard to precision statements for independent assurance sampling and testing. The response was that the assurance tests are to check the reliability of the acceptance test results;therefore it is not necessary to have statistically proven precision statements to perform this fmctfon. The FHWA h s recommended, and continues to belleve?that a nngr should be used as a guide when precision statements do not exist. RESEARCH OBJECTIVE The objective of the research project is to determine a statistical range of acceptable values when comparing an independent assurance test result (based on a frequency d 2.5 percent and 10 percent of the frequency for acceptance tests) to the results of the acceptance tests. In order to meet the objective. the following tasks shalt be addressed: 1. Perform a Iherature review to ascertain what information is avatlable on comparing Independent assurance test results to acceptance test resutts. 2. Review ADOTs acceptance test program in sufftcient detail to Nly understand the amount of testing required for the lndMdual materials being sampled. 3. Determine what constitutes a measure of comparison between: a. Split samples, i.e., the fifth sample is divided into 2 portlons to be tested in the District lab and In the Project Lab. b. A population of acceptance tests results and independent assurance tests results. 4. Determine what an acceptable independent test result would be. based on the sample s&e and criteria used for acceptance, for 26 materials (with chracteridcs ranging from 1 to 15 for each material) selected by the Department and found In the Sampling Guide Schedule. Elaborate as to whether a range of values is acceptable or H simply pass, fail is sufficient Base the analysis of the independent assurance tests on a frequency of 2.5 percent and 10 percent of the frequency for acceptance tests. 5. Prepare a final report containing a thorough documentation of the findings of this study and lndude all condusions and recommendations. The Department wlil provide approximately 1200 historical files on a computer tape and the appropriate documentatton to sort and retrieve the data as needed. The historical Rles should provide the necessary test W e s from which a statistician can devefop a program to use for testing a confidence level and determining what a favorable comparison would be. EXPECTED IMPLEMENTATION The results of this project will be incorporated into ADOTs QualityAssurance Program in order to comply with the requirements as outlined in FHPM 6-4-2-7.

SCOPE .. . \ 1.1 The purpose of including the sampling frequency schedule in the Materials Testing Manual is to bring together in one reference source the guidelines for the sampling and testing procedures necessary to assure materials quality. This sampling schedule supersedes all Sampling Guide Schedules and directives. previous The sampling frequency has been established to current production capabilities, relate - to staffing abilities and FHWA regulations. It is the intent of this schedule to give guidance to personnel responsible for sampling and testing materials, yet allow them reasonable latitude for adapting to specific project needs. The frequency may vary for individual projects or phases of projects in accordance with job conditions such as the uniformity of materials at the source, the methods and equipment used, and weather conditions. The number of samples and the distribution of the locations from which they are taken should be such as to adequately assure or verify that the materials incorporated and construction produced are acceptable in accordance with the plans and specifications. The Engineer may direct that less acceptance sampling be accomplished in particular cases of 1 imited quantities of materials on the project, or for small projects. Conversely, he may direct that a greater amount of acceptance testing than that shown as "minimum sampling frequencyn be done when he deems necessary for adequate materials quality control. Reliance should not be placed wholly on the results of sampling and testing in determining the acceptability of the materials and construction work. The sampling and testing should be supplemented by sufficient visual inspection of the materials as a whole to determine whether the samples and tests are reasonably representative of the entire mass of materials. In addition, there should be sufficient observation of the actual construction operations and processes to ascertain whether they can be expected t o consistently produce uniformly satisfactory results. Sampling Guide Schedule December 1987 2. ACCEPTAriCE SAMPLING AND TESTING The following tables for sampling frequency apply only to acceptance sampling and testing- Table 9 is an index of the materials referenced to in Tables 1 through 8. Also given in the index is a listing of the corresponding abbreviations when applicable"Independent Assurance Sampling" and correlation sampling (splits with project and District) are discussed later in this document. by manufacturer's material Acceptance certification, will be in accordance with Section 106.05 of the Standard Specifications. Small quantities may be accepted on the basis manufacturer's material certification or based upon visual observations of the Engineer. Small quantities may be considered to be approximately 500 cubic yards or less of processed aggregate material or approximately 20 tons of bituninous or portland cement and flyash. A small quantity of portland cement concrete should be considered to be 5 cubic yards or less. The Engineer should exercise careful judgement in the acceptance of small quantities. These considerations must include the significance of the product to the construction as well as the quantity. The recommended sizes of small quantities are to be considered approximate, not maximums. Some materials are pre-sampled and pre-approved at the supplier*^ yard by the District or Central Laboratory and tagged with an ADOT green sticker with the project number, date sampled and lab number on it. For materials that are green tagged, it is not necessary to do any further However, the proper laboratory should sampling be notified for verification of the materials acceptability. . 3. INDEPENDENT ASSURANCE SAMPLING AND TESTING 3.1 Independent assurance sampling normally be limited to: and testing will 3.1.1 Naturally occurring materials such as soils and aggregates, and mixtures containing naturally occurring materials. Sampling Guide Schedule December 1987 . Processed aggregates processed aggregates. and mixtures .- containing K :L:- The independent assurance sampling and testing program is to be separate from acceptance and correlation sampling and testing. Whenever practical the independent assurance sample will be split with the project laboratory. This will provide information relative to the sampling and testing variance. Independent assurance samples are to be taken and tested by the District Materials Engineer or a designated representative. Should this laboratory be involved with acceptance testing, the independent assurance samples must be tested by the Materials1 Section Central Laboratory. All testing must be accomplished with equipment that is not used for project acceptance testing. The results of the independent assurance sampling will be compared by the District Materials Engineer, to the project level splits and acceptance tests to determine if the comparison is favorable. The results of tests on independent assurance samples are to be promptly compared with those obtained from acceptance samples representing similar materials and an evaluation made as to the dependability and accuracy of the acceptance sampling and testing. To obtain similar materials, those taking independent assurance samples may take samples at the same time the project takes acceptance samples or split the samples, if desired, but correlation samples are not to be used as independent assurance samples. The results of tests and evaluations made with other comments are to be reported on the 'IReport of Independent Assurance Sampling and Testing" form (copy attached). As indicated, copies of the completed form shall be sent promptly to the Resident Engineer, Area Engineer, District Engineer, and Materials Section, with a copy retained in the District lab file. Independent assurance samples should be obtained early in the production of any particular material type or as soon after processing mixtures as is practical for the particular testing purpose. The number of independent assurance samples are indicated on the Sample Check List. The frequency is established as at least one for each material Sampling Guide Schedule December 1987 type per project but in no event should the frequency be less than 2.5 percent, as a percentage of the number of acceptance tests. Therefore, if the sample check list does not a material that requires independent indicate assurance sampling, it should be added to the sample check list and tested accordingly. Independent assurance samples will not be required on small quantities. This decision will be made by the Quality Assurance Branch of the Materials Section and presented on the "Sample Checklist". The Quality Assurance Branch should be contacted regarding any small quantity item not appearing on the "Sample Checklistw. Additional independent assurance samples shall be taken if the results of the acceptance tests and the independent assurance tests vary significantly. As a basis for evaluation, the Materials Section has prepared a Policy and Procedure Directive on the subject of Independent Assurance Sampling and Testing. This 2. P. & D. provides ranges for acceptable correlation. Shoald the results of any comparison exceed those be ranges additional investigations must initiated. The investigations may include the inspection of Project Laboratory facilities, equipment and procedure. In any event, an additional sample must be taken to verify the source of the variance has been eliminated. All measures taken to mitigate a deficiency shall be documented on the "Report of Independent Assurance Sampling and Testing". 4. CORRELATION SAMPLING AND TESTING 4.1 The following supersedes Policy and Procedure Directive 81-5, wCorrelation of Sample Test ResuItsl* . 4.2 Correlation sampling and testing is a separate program from the independent assurance sampling and testing program. 4.3 Two way splits of acceptance samples shall be obtained for testing by project and district laboratory on a regular basis. It is recommended that approximately every fifth sample be split. A prompt comparison and evaluation should be made of test results so that any necessary corrective action may be taken.

DIS I nlCT MATERIALS ENGINEER (SIGN& TllREl - - - - Appendix D Location of Data Fields in the ADOT Construction Materials Data Base On February 26, 1988, John Eisenberg presented a revised list of the material test that ADOT wishes to review as part of the quality assurance program. Review of this list found that some of the tests identified on the list were not on the data sheets. Mr. Eisenberg said we can ignore any tests that are not explicitly identified in the data sheets. This eliminated the need to review several tests : Abrasion Resistivity PH Absorption Coating Index Mortar Strength Soundness Moisture content of asphalt concrete materials Ross Count Thickness Marshall Stability Marshall Flow Rice Density Mr. Eisenberg also indicated we do not need to evaluate Top Soil and Slurry Backfill. Don Green indicated that we do not need to evaluate lime and cement treated bases. In addition, no tests were defined for Rock for Wire Tied Riprap and Rock for Grouted Riprap. The tests for Aggregate for RM are controlled by special provision and therefore can not be extracted from the current data base. Finally, there are very few data elements for aggregates for LC and therefore we could assume the variability of concrete aggregates can represent the variability of the aggregate for LC. The list of tests for each material identifies using the Flakeness Index and Sand Equivalent for several materials. However, the Flakiness Index is only used in the data base when the material type in columns 7 and 8 is CM. The Sand Equivalent test is only used in the data base when the material type in column 7 and 8 is FA and the type in column 9 10 is S. Based on this review of the required material tests, the attached table was prepared to define the cards and columns for the data in the data base. Review of the specifications for the data base indicates there are several complexities to the way some of the data are recorded. Thus, a review of each of the fields on each of the cards is in order. CARD Pi This card contains identification information for each test that is performed. The sample identification are in columns 3 through 19. This information should match the information in the same columns on cards P2 and P3. The only other data field that has particular significance is the METHOD information in column 35. This column should contain an A, C, or D for Proctor Method codes A, C, and D respectively. These codes refer to the type of Proctor test performed. Methods C and D are used for cinder type materials so the majority of cases should be A. In reviewing a sample of the database, it was noted that there are other values in this column. The meaning of values other than blank, A, C, or D are unknown at this time. CARD P2 This card contains data associated with the Proctor test. The primary data of interest are the Proctor of the material smaller than the #4 in columns 39 to 42, and the field density in columns 57 to 60. None of the other information are of interest at this time. CARD P3 This card contains comments about the tests reported on card P2. At this time the information on these cards is not of interest. However, some of the comment columns on this card were used to store miscellaneous data, so this card may be important in the future project. CARD M 1 This card contains identification of materials gradation tests. The needed identification tests are also contained on the M2 card. The other information on this card is not needed at this time. CARDM2 Unfortunately, there are two cards with M2 in columns 1 and 2, the materials and gradation card and the asphalt concrete pay factor tabulation. Columns 1 through 19 of these cards are the same with the exception the pay factor tabulation card has the material, purpose, and lab fields filled in with AC, A, and P respectively. The other fields on these cards have different definitions. These cards can be distimguished by examining columns 16 and 17; a number in these cards indicates a Pay Factor Card, there are no numbers in these columns for the material gradation cards. The Suffix or Lot# columns, 16 to 17, have significance for the future evaluation. If there is a number in these columns then the test was for statistical acceptance of asphalt concrete only. A letter in these columns indicates a replicate test, usually for compaction or gradation. For the materials gradation card, there are two sets of columns that have a variable meaning. The standard definition of columns 66 to 67 is the Plasticity Index, PI. However, if the material type in columns 7 to 8 is LW for Cover Material, then the value in columns 66 to 67 is the Flakiness Index. Although the Flakiness Index is now used for other materials, the data base we are working with only has results for Cover Materials. The other exception is in columns 71 to 72, which is normally defined as the Percent Crushed Faces. When the material type in columns 7 to 8 is Fine Aggregate and the type in columns 9 to 10 is S ('it may be either S blank or blank S) then columns 71 to 72 contain the values for the Sand Equivalent test. The data base we are working with only has Sand Equivalent results for type S Fine Aggregates. These exceptions are correctly identified in the attached table of the data layout. ADOT relies on the ASTM specifications for the gradation of course aggregates for concrete, material type CA. The sieves and the gradation requirements for each sieve in the ASTM specifications varies depending on the class of t h e material. The class of the material is not specified on the ADOT gradation card. Thus, a data layout specification could not be prepared for t h e initial investigation i n t o t h e data base, This is an area that can be further explored in the second phase of the project. All other columns of the material gradation card should have a single definition as defined in the table of the data lay out. However, in reviewing the sample data base comments were found on card M4 indicating that in one case there was a change order that called for a specification for an 114 inch sieve rather than for the standard 3/8 inch sieve so the data for the 1/4 inch sieve were recorded in the columns for the 3/8 inch sieve. Detection of this type of variance in the data base will require manual review of all of the M4 cards. Without reviewing a larger sample of the data base, we do not know how prevalent these exceptions are nor do we know the effect of ignoring these exceptions. CARD n3 This card contains voids analysis for asphalt concrete. We have not been requested to evaluate these data, thus the M3 card can be ignored. CARD MI This card contains comments about the test, As noted above, it may be necessary to review the data on this card to find exceptions to the definition of the data cards. Also the M4 card was used to record data for tests that are not defined in the definition of the M2 fields. Review of the sample data set shows there are data for sand equivalent, resistivity, pH, etc. tests on the M4 card. If we need to access these data in the future, then rules for searching through the fields of the M4 card will be required. These rules will probably be complicated as there was not a standard method for recording the data. CARD MS This card is only used with the pay factor tabulation M2 card. The only data on the M5 card is the number of tons i n k h e lot which the data on the M2 represents. Thus we will probably not need to use this card. CARD Xl This card is used for identification of concrete tests. The data on this card are not required for this project. This card is used for tests at the concrete batch plant and no data from this card are required for this project. CARD K3 This card is used for tests at the concrete site tests and no data from this card are required for this project. CARD x4 This card is used for tests at the concrete site tests. The data for the entrained air content and measured slump in columns 21 to 23 and 39 to 41 respectively are required for this project. CARD XS This card should contain lab tests of concrete at times other than 28 days. The instructions for test results from Don Green did not specify the time of testing, in which case the normal assumption is to use the test results at 28 days. Discussions with ADOT personnel indicated there was some confusion in filling out this card and that sometimes this card was used for 28 day strength tests. Thus, the AGE columns 21 to 23 should be examined to determine if the card has data for the strength at 28 days. CARD A6 The AGE field, columns 21 to 23 should be examined to verify that the data are for 28 days. The average compressive strength at 28 days is recorded in columns 69 to 73. These columns are also used for the results of beam and Schmidt hammer tests. The results of the compressive strength at 28 days should always be greater than 1000 where as the results of the other tests should always be less than 1000. This criteria should be sufficiently robust to distinguish the data in this field. CARD A7 This card contains comments about the concrete tests and therefore should not be required for this project. CARD C1 Some concrete strength data may be recorded on the "Ctl series of cards. The number of C1 cards should be counted to determine if there is a significant number of these cards. SUMMARY The recommendations presented in this memo are based on the current understanding of the methods used to record the data in the materials data base. The number of exceptions noted in this memo compromises the level of confidence in these recommendations. The analysis of the data base was performed with the understanding that some parts of the analysis may need to be repeated if exceptions are found in the way the data are recorded or if more accurate information becomes available.
