This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text. The warm mix asphalt (WMA) refers to technologies that allow a significant reduction of mixing and compaction temperatures of asphalt mixes through lowering the viscosity of asphalt binders. In this paper, Shell90 # and SK70 # are two matrix asphalt with Sasobit® modifier to prepare for WMA's penetration and ductility, and calculate the equivalent crisp points, evaluate the low temperature performance at 5°C and 15°C, respectively. The results indicate that compared with the Shell90# without and with 5% Sasobit®, its penetration and ductility were reduced by 24.5%, 65.5% at 15°C. For SK70#, its penetration and ductility were reduced by 25.0%, 67.1%. WMA equivalent crisp points test with Shell90 # and SK70 #, compared with the matrix asphalt reduced by 10.03°C and 4.02°C, the addition of 3% Sasobit® to two matrix asphalt binders may also reduce ductility by 22.5% and 26.2%, respectively at 5°C.
