The 2007 Canadian Asphalt Exchange Program(CAEP)2007 Summary

摘要

This report documents the results of the 2007 Canadian Asphalt Exchange Program (CAEP). Sixteenrnagencies participated in the 2007 Canadian Asphalt Exchange Program. The exchange provides anrnopportunity for participants to compare their test results with those of other laboratories in order tornprovide a mechanism for reviewing and refining existing test procedures. The exchange also providesrninformation to participants on their individual test procedures and equipment.rnFive types of binder material were tested in the 2007 exchange: a 150-200A asphalt cement; an MC 250rnasphalt cutback; an HF 150S asphalt emulsion; an HF 150P polymer modified asphalt emulsion; and arnbinder PG 58-28. All participants were given identical material samples to evaluate.rnThe test result analysis was based on the American Society for Testing and Materials (ASTM) E691-92,rnStandard Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test Method.rnThis procedure was used to evaluate the repeatability and reproducibility standard deviations for therndifferent test procedures performed in the asphalt exchange. This information was used to determine thern95 percent repeatability and reproducibility limits for each test procedure. The analysis procedure alsornprovided information for each participant to determine if their test results were consistent with those of thernother laboratories.rnThe exchange program is voluntary and cannot be used for pre-qualification or specification purposes.rnThe complete report is available on the Internet at Saskatchewan Ministry of Highways andrnInfrastructure’s web site: http://www.highways.gov.sk.ca/caep-internet07/
