Improvement of recycled concrete aggregate using polyvinyl alcohol for pavement applications

This thesis is to study the possibility of Recycled Concrete Aggregate (RCA) modified by Polyvinyl Alcohol (PVA) and Fly Ash (FA) for using in pavement applications. Utilities of RCA reduce both waste concrete from demolition and the devastating of natural aggregate sources effectively. But, certain limitations such as low crushing strength and low abrasion resistance makes the flexural strength properties of RCA concrete and RCA base/subbase lower than the material makes from Natural Aggregate. However, the flexural strength of RCA can be improve by using PVA and FA. Therefore, the use of RCA together with PVA and FA in road engineering applications is useful in term of engineering and economic and environmental perspectives.
