Abstract
The highway construction industry can effectively use large quantities of diverse materials. The use of waste byproducts in lieu of virgin materials for instance, would relieve some of the burden associated with disposal and may provide an inexpensive and advantageous construction product. Moreover, the escalating cost of materials and energy and the lack of resources available have motivated highway engineers to explore new alternatives in building roads and rehabilitating the existing ones. At the same time, from a highway engineering perspective, recovered materials should be used in such a manner that the expected performance of the pavement will not be compromised. Although, good amount of research has been conducted on the use of waste materials in the highways construction industry, the mechanical and physical properties of such modified materials with waste ones required more clarifications
