Description

 

In addition to the lack of comprehensive local supply and demand studies and cost-benefit analyses, one of the major impediments of enhancing the practice of sustained recycling in C&D projects is the existing regulations and standards that limit (or prohibit) the large scale use of recycled materials. In the absence of extensive research and validated testing methods, certain categories of C&D debris have been only used in a relatively limited number of new construction or land development projects. In particular, the investigators have identified opportunities to use large fraction of these materials as aggregates or additives in concrete or hot mix asphalt (HMA). This study will focus on tear-off roof shingles and will investigate the effect of asphalt binder grade and content, and content and different shingle sources and proportions on HMA mixture properties. The research team will design a testing regime in compliance with statewide regulations and standards, which will include testing a matrix of laboratory-produced mixtures that incorporate different contents of asphalt binder and recycled asphalt shingles (RAS).

Status

 

At this time, our team is working on:

 

Task 1: C&D Debris Best Management Practices and Recovered Material Market Analysis

  • Analyzing the relationship between annual economic growth (GDP indicator) and C&D generation over the past ten years.

Task 2: Laboratory Testing of Recycled Asphalt Roof Shingles

  • Conducting a thorough literature review on FDOT regulations and standards for hot-mix asphalt (HMA) testing in order to develop a comprehensive testing methodology.
