Study On Asphalt Pavement Active’ Anticoagulant Ice For Highway Of Wet Mountain

There is a lot of snow mountain in jiangxi province, ice is one of the main severe weather and higher frequency every winter. It is easy to form asphalt pavement pour ice in winter leading to a significant reduction in their ability to skid. Both weaken the traffic capacity of roads, but also easy to produce malignant traffic accidents. It can also cause serious traffic disruption, can’t normal people’s life and production and even endanger people’s life and property safety.In view of the above, this paper summarizes the domestic and foreign status of the research of asphalt pavement of anticoagulant ice, for the research of anticoagulation ice asphalt mixture. Goal is to solve the problem of the safety of asphalt road surface ice. By indoor tests and theoretical analysis, combined with independent research and development of new ice anticoagulant agent solves the anticoagulation ice asphalt mixture proportion design and anticoagulation performance evaluation, etc. Ensure anticoagulant ice asphalt mixture of water stable performance, high temperature performance, low temperature performance road performance to meet regulatory requirements. Finally, through the test road paving, put forward the anticoagulation ice special construction technology of asphalt pavement to pour ice on the asphalt pavement of high incidence area for technical guidance of new roads.By studying the main draw the following conclusions:(1)Combined with road performance test results with simulated ice condensation,laboratory test results, both economic efficiency considerations, determine the anticoagulant ice asphalt mixture of anticoagulant agent the best dosage is 5%, the target porosity control in 2%~3%.( 2) Base mixture mixing evenly and then according to the dosage with anticoagulant ice agent mixing 5s~10s. Construction control of the temperature of each link are higher than the ordinary asphalt mixture 5℃ to 10℃. Because of the fine aggregate content is more, need to increase the number of complex pressure in the process of rolling.( 3) Through experiment study, think that this design of asphalt mixture with anticoagulant ice meet the specification requirements of performance and excellent anticoagulant effect of ice.
