摘要：
To determine the compacting temperatures of rubberized asphalt (RA) mixtures containing warm mix asphalt (WMA) additives, a total of three RA binders were produced in laboratory using two kinds of WMA additives (Sasobit and CW), and one control binder without WMA additive. Brook rotational viscosity test of RA binders and Marshall compaction test of RA mixtures at various temperatures were conduced to study the viscosity-temperature properties of RA binders with WMA additives and analyze the volumetric properties of RA mixtures with different compacting temperatures, respectively. The results indicate that both Sasobit and CW can decline viscosity at testing temperatures and the compacting temperatures of RA mixes containing CW and Sasobit are 160 degrees C and 154 degrees C, respectively.
