STABILITY-ENHANCING ADMIXTURE AND IMPROVED BASE STABILIZATION PROCESS FOR USE IN ROADWAY CONSTRUCTION AND RECONSTRUCTION

摘要

The present invention provides a process for stabilizing the base course of a roadway through steps including admixing an asphalt emulsion and Portland cement with granulated base materials. The base course formed through this process is stronger and less permeable than base materials stabilized with either Portland cement or an asphalt emulsion alone. The method of base stabilization includes the steps of evaluating the base materials, designing a proportional mixture of the base materials and stabilizing agents, and forming a stabilized base course.
