| Yunnan-Guizhou Plateau in China Sichuan mountain humid and rainy in winter, the road to easily slide the formation of condensation of ice and a significant reduction in capacity, not only reduces the road capacity, it is easy creating a vicious traffic accidents, and road and its subsidiary structures will produce damage can also cause serious traffic disruption, people's living and production can not be normal, and even endanger people's lives and property. This gives our road engineers sounded the alarm, building roads with anticoagulant properties of ice is imminent. Therefore, this paper support the national science and technology project "Yunnan, Guizhou, Sichuan Plateau pour wet ground ice (dark ice) control techniques", were anticoagulant mixture of ice. This paper, through experimental research and theoretical analysis of aggregate through the preparation of ice starting anticoagulation, the anticoagulant solution mixture of ice goal ice mix design and performance evaluation of anticoagulation and other issues, while ensuring high-temperature asphalt anticoagulant properties of ice , low temperature performance, such as water, road performance and stable performance to meet regulatory requirements.In this paper, the results are: the formation of ice on coagulation mechanism and the mechanism of de-icing salt, sodium chloride and calcium chloride used as anticoagulant ice studied composition with salt, prepared with anticoagulant mixture of ice aggregate Through laboratory tests, confirmed the release of chloride can be, the possibility of ice anticoagulation; by law to replace an equal volume of ice aggregate anticoagulant replace the vast difference between the density of ordinary aggregate to form a new anticoagulant ice mixture, using the immersion method, obtain the maximum theoretical relative density, through the Marshall test, to determine its most recent Asphalt; comparative analysis of laboratory experiments to evaluate anticoagulant anticoagulant mixture of ice ice effect, as a proof of species of special asphalt mixture can reduce the mountain of ice pour the road is icy disaster-prone areas point, reducing the probability of condensate produced ice, while maintaining high temperature performance, low temperature, water, road performance and stable performance, etc. to meet the specifications; briefed anticoagulant ice asphalt pavement construction technology, the construction process should be noted that the problem is analyzed. This finally shows that the ice anticoagulant anticoagulant mixture of ice with good performance, can reduce the freezing point of the winter road, but also has good high temperature performance, low temperature, water stability, with a superior road performance, the Yunnan, Guizhou, Sichuan Plateau pour ice-prone mountain highway construction has broad application prospects. |
