Elastic modulus of asphalt with chemically stabilized rubber bitumen

Abstract

The chemically stabilized rubber bitumen (CSRB) has been developed by researchers from the company MOL and the Pannonian University (Hungary). The CSRB is made of used automobile tyres, and it improves the quality of pavement, while also enabling an efficient use of used automobile tyres. Mechanical properties of the chemically stabilized crumb rubber bitumen are analysed in the paper. Although test results have shown that CSRB properties are similar to those of the polymer modified bitumen, the CSRB results have proven to be better at low temperatures.
