IMPROVED METHODS OF ESTIMATING STRIPPED AREA IN ASPHALT STRIPPING TESTS

WORK WAS DIRECTED TOWARD DEVELOPING A BETTER METHOD THAN VISUAL ESTIMATION FOR DETERMINING THE EXTENT OF STRIPPING. NO ATTEMPT WAS MADE TO IMPROVE ON THE SAMPLE PREPARATION TECHNIQUES SPECIFIED IN THE VARIOUS STATE HIGHWAY PROCEDURES. MEASUREMENT OF THE EXTENT OF STRIPPING WAS APPROACHED IN TWO WAYS: (1) INDIRECT AND (2) DIRECT MEASUREMENT OF AREA. IN THE INDIRECT METHODS, SOME FACTORS OTHER THAN AREA, THAT IS RELATED TO EITHER THE COATED OR UNCOATED AREA, IS MEASURED. INDIRECT MEASUREMENT METHODS GENERALLY HAVE GREATER POSSIBILITIES FOR BEING CONDUCTED AS ROUTINE TESTS. THE EARLY WORK ON INDIRECT MEASUREMENT METHODS, SUCH AS DYEADSORPTION TECHNIQUES, SHOWED THAT A DIRECT MEASUREMENT METHOD WOULD BE REQUIRED AS A RESEARCH TOOL TO EVALUATE ANY OTHER METHODS THAT MIGHT BE DEVELOPED. THE ORDINARY VISUAL ESTIMATION METHOD IS NOT SUFFICIENTLY RELIABLE FOR THIS PURPOSE. CONSEQUENTLY, EMPHASIS WAS SHIFTED TO DEVELOPING A DIRECT MEASUREMENT TEST AS THE FIRST STEP TOWARD THE ULTIMATE GOAL OF A ROUTINE TEST THAT MIGHT BE ACCEPTED BY THE STATE HIGHWAY DEPARTMENTS. /AUTHOR/
