THE CURRENT USE OF RECYCLABLE MATERIALS IN HOT MIX ASPHALT CONCRETE HIGHWAY PAVEMENTS IN THE UNITED STATES
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. Although there are a growing number of procedures and processes being continuously developed which well address this general issue, the objective of this paper was to research and investigate the potential specific disposal of waste materials by usage in Hot Mix Asphalt Concrete (HMAC) pavements. The particular purpose of this effort was to establish the current nationwide position of all of the fifty states and the District of Columbia in regard to the disposal and/or usage of various waste materials in HMAC mixtures as they apply to an asphalt concrete pavement. The general procedure in preparing this paper was two fold. First, a search was made to identify all possible waste materials that may have potential for usage in an HMAC mixture. Second, all the fifty State Departments of Transportation as well as the District of Columbia were polled in order to establish the most current status and, where possible, volumes of waste material usage in this country in HMAC mixtures. The results of this study identified the waste materials that are available for use in HMAC mixtures, both currently and in the future. The nationwide survey of states and the District of Columbia verified the types of waste materials being used in HMAC mixtures; where the waste material is used within the pavement structure; what waste materials have been accepted; what waste materials are at present experimental in nature; and what waste materials have been rejected.
