    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.
