Application of Construction and Building Debris as Base and Subbase Materials in Rigid Pavement
Publication: Journal of Transportation Engineering
Volume 129, Issue 5
Abstract
This research presents the test results of a laboratory and field study performed to investigate the characteristics and performance of dry and wet recycled concrete aggregate (RCA) as base and subbase materials for concrete pavement. The physical properties of the RCA were investigated in terms of the moisture-density relationship, particle index, and fine aggregate angularity. Performance concerns have focused on compactibility, stability, shear resistance, and particle breakage of the RCA. These were evaluated in the laboratory using the U.S. Army Corps of Engineers Gyratory Testing Machine. The falling weight deflectometer was used to measure the deflection of pavement sections constructed with RCA base and subbase in the subbase material and may be comparable to crushed stone aggregate.
