The Recycled Materials Resource Center (RMRC) is a national center created to promote the appropriate use of recycled materials in the highway environment. Approximately 30 research projects will be funded and conducted by RMRC over the first 6 years of operation. This article presents a summary of the 10 ongoing projects: mitigating alkali-silica reaction in recycled concrete, environmental weathering of granular waste materials impact on environmental performance, concrete mixtures with inclusions to improve the sound-absorbing capacity of portland cement concrete pavements, development of application-specific source term/fate/transport models and approaches for recycled materials use in the highway environment, leaching from granular materials used in highway construction during intermittent wetting, development and preparation of specifications for recycled materials in transportation applications, determination of the number of compaction revolutions for cold-in-place recycled mixture design using the SHRP gyratory compactor, development of a rational and practical mix design system for full-depth reclamation, fatigue durability of stabilized recycled aggregate base course containing fly ash and waste-plastic strip reinforcement, and lightweight synthetic aggregate from fly ash and waste plastics. |
