Abstract

Research Project HR-124, "Development of a Laboratory Durability Test for Asphalts," was initiated in 1966 as a long range comprehensive program. Its ultimate objective was to develop a simple, rapid laboratory test that could be used by highway engineers to select paving asphalt according to quality, to identify inferior asphalts, and to reasonably predict the useful life of asphalts once they were incorporated in the pavements. This report, designated Progress Report No. 3, summarizes the work accomplished during the second year of the HR-124 extension (1967 - 1969), i. e., the period from 1 October 1968 to 31 October 1969.
