| Abstract: | Thinking of the disadvantages to evaluate road asphalt with current correlative indexes,such as penetration,soft point,ductility,etc.,and reflect the rheology of recycle asphalt better when the load,time and temperature change,the strategic highway research program(SHRP)was used to evaluate the in service performances of three kinds of recycle asphalt.The stability,anti-fatigue and anti-cracking at high-temperature,middle-temperature and low-temperature are analyzed.The results indicate that the performance... |
