AN APPROACH TO MEASURING THE QUALITY OF ASPHALTIC PRODUCTS

THE RENEWED SEARCH FOR TESTS WAS UNDERTAKEN IN KANSAS BECAUSE OF AN UNMISTAKABLE OBSERVATION THAT MANY ASPHALTIC PRODUCTS SINCE APPROXIMATELY 1940 WERE GENERALLY OF POORER QUALITY THAN THOSE PRODUCED PRIOR TO THAT TIME. IT WAS DECIDED IN 1947 TO START A PROJECT WHICH WOULD BRING TO LIGHT SOME OF THE EXISTING CHARACTERISTICS OF ASPHALTS USED ON THE STATE SYSTEM. IT IS BELIEVED THAT THESE FINDINGS MIGHT PROVIDE A METHOD BY WHICH FUTURE ASPHALT PRODUCTION CAN BE CONTROLLED TO GIVE CONSISTENTLY GOOD QUALITY MATERIALS. THIS SERIES OF STUDIES IS CONDUCTED IN TWO PHASES, THE FIRST DEALS WITH THE RECOVERY AND ANALYSIS OF ASPHALTS WHICH HAVE BEEN IN SERVICE FOR SEVERAL YEARS; THE SECOND PHASE EXAMINES THE CURRENT ASPHALT PRODUCTION BEFORE AND AFTER IT HAS BEEN SUBJECTED TO ACCELERATED WEATHERING TESTS. /AUTHOR/
