摘　　要：为了解决中国北方气候寒冷地区路面积雪结冰对公路发展和交通安全运营的影响,采用室内路面破冰模拟试验仪验证盐化物沥青混凝土的抑制结冰能力,通过现场观测验证路面的融雪能力。结果表明:在抑制结冰试验中提出的指标摆值平均加权衰减量与摆值平均加权衰减率,可以定量描述盐化物沥青路面的抑制结冰能力;盐化物融冰雪沥青路面与普通沥青路面相比不易积雪,且积雪与路面粘附性较差,积雪易清除。In order to solve the problem that the snow or ice on the pavement impacts on the road performance and transportation security in cold areas in northern China,this paper adopted indoor simulating tester for antifreeze pavement to verify the antifreezing capability of MFL modified asphalt concrete and its snow melting function by observing the testing process.Two indicators proposed in the antifreeze test which were defined as attenuation amount weighted average of BPN and attenuation rate weighted average of BPN could describe the antifreezing capability of MFL modified asphalt concrete pavement quantitatively.Compared with ordinary asphalt pavement,the snow on the modified asphalt concrete pavement can be melted more easily,and the adhesion of snow with the surface of road is more weak,so the snow can be cleared easily.4 tabs,5 figs,8 refs.
