Abstract
Massive amount of debris and trashes, one of the issues and problems of today's world is the especially asphalts debris resulting from the removal of worn-out pavements of urban roads. Recycled asphalt crumbs are waste materials that certainly have significant undesirable effects on the surrounding environment. Given the properties reported by these materials, there are various ways to reuse these materials. One of the applications that have been considered by researchers is the use of these materials in cement mixtures, including concrete production. This is while that a large amount of asphalt fragment is continuously produced in the repair and maintenance of roads. It is therefore desirable to be used in conventional mixtures used in Construction of roads pavement. In this regard, the present study investigates the performance Evaluation of Roller Compacted Concrete Pavement make by Recycled Asphalt using Micro Silica with the aim of reducing waste and its negative impacts on the environment. By examining the documentation and performing numerous experiments, it has been found that roller compact concrete made from recycled asphalt can be used as a suitable pavement for low traffic and rural roads, as well as for the final covering of a wide range of sidewalks. It is also suitable as CBT.
