Utilization of Marginal Construction Materials for LOC.
Abstract
The purpose of this report is to develop methodology and procedures for using marginal quality aggregates (aggregates not meeting existing specifications) in the construction of asphalt and portland cement concrete surface pavement layers. The report describes a laboratory study performed on bituminous mixes made from marginal aggregate materials and the testing of a specially designed test section consisting of both flexible and rigid pavement surface layers made of marginal quality aggregates. Also presented are construction techniques and the behavior of the marginal aggregate mixes subjected to accelerated 5-ton military dump truck and two types of tracked vehicle traffic. Recommended properties of asphalt and portland cement concrete mixes made of marginal aggregate materials are presented to aid the military engineer in constructing paved surfaces that are to be used only for limited traffic and short periods of service life.
