Recycled Material Availability in Maryland

Principal Investigator(s) 

Currently the use of recycled materials in highway applications is limited due to regulatory, environmental, and technical restrictions on their potential use. The lack of performance information when these recycled materials are used in highway applications is also a major stumbling block. It is the objective of this research to (i) identify such constraints and propose methods to reduce or eliminate those restrictions, (ii) document the state of the art practice on the use of the selected recycled materials, (iii) review the known performance of each listed recycled material based on past experience, and (iv) develop the technical requirements for their safe use in alternative applications of highway projects for Maryland conditions.
