An overview of crumb rubber modified asphalt
Roadways are considered one of the most important elements of infrastructure and they play an essential role in our daily lives. In road pavement construction, the use of crumb rubber in the modification of bitumen binder is considered as a smart solution for sustainable development by reusing waste materials. It is believed that crumb rubber modifier (CRM) could be one of the alternative polym...
متن کاملInfluence of Rubber Size on Properties of Crumb Rubber Mortars
Studies on the properties and applications of rubber cement-based materials are well documented. The sizes of rubbers used in these materials varied. However, information about the effects of rubber size on the properties of rubber cement-based materials, especially pore structure, mechanical strengths, and drying shrinkage properties, remains limited. Three groups of rubber with major particle...
متن کاملEffect of Reclaimed rubber Modification on the Rheological Properties and Rutting Resistance of Asphalt Binders
In this paper, the effect of reclaimed rubber modification on the rheological characteristics of asphalt binders is studied. Reclaimed rubber with the extent of 12, 16 and 20 is added to the neat asphalt binder and then shear complex modulus is obtained for neat and modified asphalt binder via Dynamic Shear Rheometer (DSR) test. Using Christensen-Anderson- Marasteanu (CAM) model, master curves ...
متن کاملEvaluating the Performance of Crumb Rubber Modified Binders used in Isfahan Province
The performance of asphalt binders at high and low temperatures has an important role on the rutting and crackingresistance of asphalt pavements. Crumb Rubber Modified (CRM) is one of the asphalt modifiers that improves asphaltphysical and mechanical properties and helps reducing environmental pollution. In this research, three unmodifiedand six CRM modified binders were teste...
متن کاملAsphalt-Rubber An Anchor to Crumb Rubber Markets Third Joint UNCTAD/IRSG Workshop on Rubber and the Environment International Rubber Forum Veracruz, Mexico
2 Executive Summary The purpose of this paper is to familiarize the reader with the paving material asphalt-rubber (A-R) by providing historical perspective on its development and obstacles to its development. A-R has been a constant and stable market for crumb rubber producers in the United States most significantly within the vicinity of Arizona, California, and Florida. Agencies use A-R beca...
