UTILIZATION OF LOCAL SANDS IN HIGHWAY CONSTRUCTION

The overall purpose of this project was to determine the feasibility of using coastal sands and gravels as construction or specialty materials. A comprehensive study was made of the variables affecting the fatigue and rutting performance of sand and sand-stone blend asphalt mixes having approximately 16, 40, 70, and 100% sand. Other variables studied included asphalt content, voids content, gradation and aggregate source. The fatigue performance of sand-cement specimens was evaluated for two different sands with fatigue tests performed on seven different mixes. Soluble salt contents of the sands were also evaluated to determine if the salt concentrations were high enough to affect performance. Preliminary design criterion and mix specifications were developed for utilizing local sands in sand-asphalt and sand-stone asphalt mixes and also in sand-cement bases of flexible highway pavements. The recommendations presented were based on the results of the detailed laboratory studies, interviews and field inspections. The significant findings of the study are presented.
