In summary, this paper presents the findings from the laboratory evaluation and field performance monitoring for crumb rubber and latex modified asphalt mixes in comparison with the standard asphalt mixes used in Singapore. The performance of the modified asphalt mixes was monitored using the on-board sound intensity (OBSI) system for tyre-pavement noise, a high speed laser profiler for riding quality and other surface condition parameters as well as the sideway-force coefficient routine investigation machine (SCRIM) for skid resistance. For field performance monitoring, trial sections of crumb rubber and latex modified asphalt mixes were implemented along the selected expressway and major arterial road in Singapore. A series of laboratory tests was then performed to evaluate the performance of the modified asphalt mixes by conducting sound absorption and other performance tests for the acoustic and mechanical properties of the mixes. For laboratory evaluation, the content of crumb rubber and latex was varied to obtain the optimum rubber content in asphalt mixes. The study involved two phases namely 1) laboratory evaluation and 2) field performance monitoring. strength and durability) performance of the rubber modified asphalt mixes. In this study, the asphalt mixes with different void ratios have been modified using crumb rubber and latex to investigate the acoustic and mechanical (e.g. The ignition test is the most common method used to determine HMA asphalt binder content. Therefore, it is important in HMA quality assurance, pavement forensic investigations and HMA research. Latexite Airport Grade Driveway Filler Sealer is an asphalt emulsion based driveway sealer. Asphalt binder content affects HMA mixture performance in the areas of stiffness, strength, durability, fatigue life, raveling, rutting and moisture damage. Performance Evaluation of Crumb Rubber and Latex Modified Asphalt MixesĬrumb rubber is widely used as pavement materials to enhance the performance of asphalt mixes such as rut resistance, low temperature cracking and stripping damages. 99 2631728 RESISTO Acrylic Asphalt Restorer 6 Years. ![]()
