DOWNLOAD EBOOKCrumb rubber produced from scrap tires has been widely applied in asphalt mixtures to improve the pavement performance. Warm-mix technology has also been employed to lower the production temperature of asphalt mixtures. The objective of this article is to investigate the effects of warm-mix additive types and crumb rubber concentration on the resistance to deformation of crumb rubber-modified (CRM) binders through the repeated creep and recovery test (RCRT), dynamic shear rheometer (DSR), and rotational viscosity test. The CRM binders with crumb rubber concentrations of 10 %, 15 %, 20 %, and 25 % were prepared first as the control binders. Then, three types of warm-mix additives, Sasobit, RH, and Advera, were added into the CRM asphalt to produce CRM warm-mix asphalt (WMA) binder. Generally, the workability of CRM asphalt can be improved with the addition of warm-mix additives. The effect of warm-mix additive on the high-temperature performance is highly dependent on the crumb rubber dosage. The RCRT results overall showed that the warm-mix additives can improve the high-temperature performance of asphalt when the crumb rubber concentration is low. However, according to the DSR test, Sasobit improved the rutting resistance of CRM asphalt, while the RH and Advera sacrificed the rutting resistance. The inconsistency between the RCRT and DSR results suggests that it may be necessary to conduct both the tests when investigating the high-temperature performance of CRM asphalt with warm-mix additives.

DOWNLOAD EBOOKDocuments the construction and performance of the research study which was initiated to address section 1038(d) of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA). The project selected to demonstrate the crumb rubber process was located on Platt Canyon (SH 75) from Bowles to C470 in the Denver metropolitan area. The project was a low volume roadway and quantities of crumb rubber introduced into the mix were minimal. This was to reduce risk in terms of premature failure and Colorado's limited experience with crumb rubber. Because of this limited experience, the "dry" process was selected. The project contained four different mix designs. A mix containing 1% [20 lb/ton (10 kg/Mg)] crumb rubber, a mix containing 1 lb/ton (0.5 kg/Mg), a mix containing 3 lb/ton (1.5 kg/Mg) and a mix which contained no rubber were placed on the project.

DOWNLOAD EBOOKSection 1038 of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) contains provisions for each State to begin incorporating scrap tire rubber into their asphalt paving materials. A workshop was developed through the cooperation of highway agencies and the asphalt industry to discuss present procedures and practices for designing and constructing asphalt pavements which incorporate scrap tire rubber (crumb rubber modifier). These workshop notes were prepared from the proceedings of the 13 workshop sessions.
