| 摘 要： | 为了解沥青混合料的流变特性,采用MMLS3进行沥青混合料的足尺（Full scale）加速加载试验,并利用便携式路面分析仪对沥青混合料流变后的隆起和下陷部分的地震波模量进行测量.试验结果表明：在荷载作用下,沥青混合料下陷量与隆起量的变化值不等;并且下陷处的地震波模量逐渐增大并趋于稳定,而隆起处的地震波模量在逐渐减小.试...

| Abstract: | In order to study the rheological properties of asphalt mixture,MMLS3 was used to conduct full scale accelerated loading test and PSPA was used to test seismic modulus of upheaval and sag when asphalt mixture came into the stage of flowing deformation.The test results showed that the sag and upheaval changed with different degree of variations under the loads,and the seismic modulus of sag increased gradually and tended to be stable,while the seismic modulus of upheaval decreased gradually.It can be proved that asphalt mixture presents non-uniformity rheological course and the change law of mechanical properties of upheaval is totally different from that of sag. |
