Title: Experimental Study on the Performance of High Modulus of Asphalt Mixture
Abstract: Aim to the hard asphalt mixture,70 # asphalt mixture,SBS modified asphalt mixture were heat-stable(for the 0.7 MPa under 50 ℃、60 ℃、70 ℃ three temperature conditions of the rutting test),low temperature crack resistance(trabecular low temperature bending test),water stability(freeze-thaw fracturing tests,residual stability test),fatigue performance(APA fatigue test).the results show that,High modulus asphalt mixtures have better resistance to rutting performance.as the limit load is about 14 000 N.at-5 ℃the high modulus asphalt mixture still has a good low-temperature anti-cracking performance.Freeze-thaw splitting results showed that AC-20C(30 #) asphalt mixture with a high intensity ratio of the freeze-thaw cleavage,with good water stability.
