containing only about 2 percent plus No. 4 aggregate, the highest densities were ob tained with the heavy pneumatic-tired roller. In 1961 the field experiments were con tinued on three additional projects. Because all materials in the 1961 experiments were graded crushed stone, it was decided that only the vibrating roller would be used.

Low density concrete mixtures (for the density values from 800 to 1300 kg/m3) were prepared by changing the volume of lightweight expanded clay aggregate (ECA) from 49.4% to 20.1%.
