TL;DR: A literature review on the existing technologies and specifications related to the production, handling and storage of RTR-MBs and on their current applications within road asphalt mixtures is presented in this article.
640 citations
TL;DR: In this paper, the use of crumb rubber in asphalt paving mixture has long been proven successful due to good compatibility and interaction between rubber particles and asphalt binder, leading to various improved properties and performance of asphalt mixtures.

TL;DR: In this article, the authors investigated the rutting resistance characteristics of the rubberized asphalt mixtures through a laboratory testing program, which included use of two rubber types ambient and cryogenically produced, four rubber contents, and three crumb rubber sizes.
Abstract: Improved understanding of rutting resistance of a rubberized asphalt concrete pavement that contains reclaimed asphalt pavement RAP is important to stimulating the use of rubberized asphalt mixtures. Use of RAP in the past has proved to be economical, environmentally sound, and effective in increasing the rutting resistance of asphalt mixtures. Rubberized asphalt has been used success- fully in improving the mechanical characteristics, such as rutting resistance, of typical hot mix asphalt HMA mixture around the country and the world. The objective of this research was to investigate the rutting resistance characteristics of the rubberized asphalt mixtures through a laboratory testing program. The experimental design included use of two rubber types ambient and cryogenically produced, four rubber contents, and three crumb rubber sizes. The results of the experiments indicated that the use of RAP and crumb rubber in the HMA can effectively improve the rut resistance of these mixes.

TL;DR: In this paper, the authors explored the utilization of the conventional fatigue analysis approach in investigating the fatigue life of rubberized asphalt concrete mixtures containing the WMA additive, and the test results indicated that the addition of crumb rubber and asphalt additive not only reduced the mixing and compaction temperatures of rubberised asphalt mixtures offset by crumbs rubber but also effectively extended the long-term performance of pavement when compared with conventional asphalt pavement.
