The aims of this study is to prospectively the aging evolution CRMA from perspective a multi-phase composite system. In study, separation was carried out by physical filtration and chemical extraction, investigated. results showed general increase in density remaining sub-phases during aging, except liquid asphalt binder phase (LABP). volume adsorbed (AABP) increased 17.91% after TFOT decreased PAV reflecting demonstrating change structure CRMA. complex shear modulus each but amplitude smaller than that 70# binder. Adsorbed (AP) AABP inhibited susceptibility high low temperature properties respectively. adsorption protection provided crumb rubber volatilisation oxidation aromatics within phase. Both its contain polymer phases. Polymer dispersion more evenly AABP, agglomeration present AP. swelling effect caused disperse unevenly.

Emission Risk and Inhibition Technology of Asphalt Fume from Crumb Rubber Modified Asphalt

Sustainability, Journal Year: 2024, Volume and Issue: 16(20), P. 8840 - 8840

Published: Oct. 12, 2024

Crumb rubber-modified asphalt mixtures have been proven to extensive utilization value in road engineering. However, the rubber releases more fumes during construction period, which causes severe harm human health and environment. This research focused on emission risk of fume from crumb asphalt, then inhibition technology was also optimized. Firstly, behavior hazardous evaluation were investigated. Then, characteristics materials evaluated. Finally, reduction inhibited identified, optimized formula determined based effect, rheological properties, cost. The results indicate that asphalts release components with an increment temperature content. Desulfurized reduces H2S NO. Benzene compounds, including paraxylene, toluene, benzene, are most released pollutants health, especially DS CRA 20% 50%. Kaolin powder expanded graphite a sufficient pore structure volume, addition while possibly promoting NO H2S. Their has significant control effect particulate matter at 170 °C 185 °C. With consideration emissions, cost, 40%-EG2%-KL2% as optimization formula. is helpful application maintenance.
