TENSILE PROPERTIES OF DENSE GRADED BITUMINOUS CONCRETE (WITH DISCUSSION)

The resistance of asphaltic concrete to cracking is dependent upon its tensile strength and extensibility characteristics. The tensile properties are affected appreciably by temperature, loading time, and other factors. In this work, attempts were made to investigate stress-strain characteristics of certain dense graded bituminous mixes at various temperatures and various rates of loading. The coarse and fine aggregates were identical in all mixes; 3 microaggregates (fillers) and 3 asphalt contents were used. The findings to date indicate relatively low and similar tensile failure strains for the practical (stable) mixes and the varied effects of temperature and loading time on the ultimate strength of the different compositions. Fibrous microaggregate increased the tensile strength of bituminous concrete at low temperatures.
