Bitumen-Sand Mixes for Road Bases
The cost of bitumen-sand mixes can be reduced by using less bitumen than is necessary for surface durability, provided they are surface-dressed to protect them from abrasion. To determine whether a road built using this technique gives adequate performance, a series of experimental mixtures was laid on the Maiduguri-Bama road in Northern Nigeria early in 1960. The mixtures were made with unheated sand and three cut-back bitumens of different viscosity. This report contains a brief description of the experiment together with the conclusions which emerged from observations during mixing and laying and during six years under traffic. (Author)
