Assessments of Water Pollutants from Asphalt Pavement Containing Recycled Rubber in Rhode Island

In this study, hot mix asphalt (HMA) specimens with and without crumb rubber modifier (CRM) were analyzed for different environmental conditions. The CRM was added to HMA through both the wet and dry process. Cylindrical specimens were tested in the Particle Entrainment System (PES) at two different temperatures and three different pH levels. Runoff was also tested from slab and chip seal specimens subjected to light, wear, and simulated rainfall. Water samples were collected in three phases: (1) water quality extraction of individual CRM samples; (2) water quality evaluation for cylindrical HMA specimens at varying environmental conditions (pH and temperature); and (3) water quality evaluation for slab HMA and chip seal specimens under simulated rainfall. Collected water samples were tested for trace metals and organics. A total of six metals were analyzed in the laboratory, i.e., Cr, Pb, Ni, Cu, Cd, and Zn. Based on the limited scope of this effort and comparison with water quality criteria, it appears that there is no evidence in this study that there will be detrimental effect on the environment or to human health.
