Abstract:
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.
