Book Description

Waste material management is becoming a very difficult challenge due to the lack of proper disposal facilities and processes as well as the environmental considerations associated with same. The objective of this paper was to research and report on the potential specific disposal of waste materials by usage in Hot Mix Asphalt Concrete (HMAC) mixtures. First, a search was made to identify all possible waste materials that may have potential for usage in an HMAC mixture. Secondly, all the fifty State Departments of Transportation and the District of Columbia were polled in order to establish their most current status on research and usage. Waste materials identified in this work included Reclaimed Asphalt Pavement (RAP), waste rubber and rubber tires, various slag and ash products and glass. The poll also identified those states or government agencies which are using waste materials as a matter of answering to existing or future legislative mandates.
