Abstract
PMMA (polymethylmethacrylate) binder is a two-component polymer material used in road construction. The addition of another component (initiator) to the resin component A results in a rapid secondary crosslinking reaction of the MMA monomer to form a high-strength coating so as to achieve the durable use of the road under special conditions. It can significantly increase the performance of keeping the road surfacedry and anti- skid, to shorten the braking distance by 30-40% or more. However, because of the long winter, the long frozen period as well as the heavy snow in the north, clearing snow has become a difficult task. Moreover, there are more traffic accidents due to the untimely snow-clearing, making a serious impact on the transportation and the security, and the problem of the failure of the slip resistance of the chemical PMMA pavement in the north in winter. Based on the chemical PMMA pavement, a numerical simulation is to be made towards the geothermal snow - melting process using FLUENT, then obtain the temperature field of the snow on the road and the snow-melting law of the interface. According to the size of the radiating pipe’s diameter, the spacing and depth of the buried pipes, comparative study is to be done to offer some reference value to the road design with geothermal snow-melting technology.
