The objective of this study is to potentially employ warm mix asphalt (WMA) in rubberized asphalt mixtures, taking the zeolite as foaming WMA additive, the rheological properties of the foamed warm rubberized asphalt were analyzed by using dynamic shear rheology (DSR) and bending beam rheology (BBR) tests, and the performance of the foamed warm rubberized asphalt mixtures was evaluated. Results show that the WMA additive dosage has a considerable effect on rheological properties of rubberized asphalt, and foamed rubberized asphalt presents a best rheological properties at a dosage of 3% (by mass). The addition of the WMA additives into the rubberized asphalt mixtures decreases the mixing and compaction temperatures. The performance tests indicate a less difference between foamed warm mix rubberized asphalt mixtures and hot mix rubberized asphalt mixtures, which can meet the requirements of technical specifications (JTG F40-2004).
Key words: rubberized asphalt; foaming warm mix; pavement performance; rheology
