THE EFFECTS OF SOIL BINDER AND MOISTURE ON BLACK BASE MIXTURES

This report describes a study which was undertaken to evaluate the effect of the amount of soil binder on the engineering properties of asphalt-treated paving materials. For this study soil binder was considered to be aggregate finer than U.S. standard sieve size No. 40. The static and repeated-load indirect tensile tests were used to measure engineering properties of aspahlt mixtures for purposes of mixture design and evaluation. Two aggregates, a rounded gravel and a crushed limestone, each with various soil binder contents, were mixed with a range of asphalt contents to produce test specimens. The engineering properties were compared for the various soil binder contents. Results of these comparisons indicated that the various engineering properties could be maximized at relatively low soil binder contents and at lower asphalt contents. (FHWA)
