Research of bituminous concrete properties with large sized aggregates of different paricle shape. Paper presented at the 47th Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1968.

A test method was developed to evaluate bituminous mixtures with large-sized aggregates. The triaxial method of test used by the Texas Highway Department for soil-aggregate combinations, as well as for dense-graded aggregates, was adopted with some modification. The basic change was close control of temperature during mixing, compaction, and texting.
