The Research On Asphalt Mixture Include Salt

In recent years, the special climate of the South continued low temperatures in winter and snow disasters, especially in early 2008, suffered a 50-year return of large snow and ice stor-ms to our traffic causing a serious impact, a number of airports suspended, a number of high-way closed, railway disruption, urban road traffic congestion, frequent accidents and other em-ergencies, in particular, extensive damage to road infrastructure. This gives our road engineer-s the alarm, can inhibit the ice road construction is imminent.Inhibition of surface coagulation of traditional ice and snow than the methods, mainly com-bining mechanical and manual operation to clear the road surface, snow, or spreading deicing salt (mostly sodium chloride, calcium chloride, etc.) to achieve except The purpose of snow a-nd ice, such method not only time consuming, and on the surrounding environment cause gr-eat pollution.Since chloride can reduce the freezing point of ice and snow, from nature to take the initi-ative to restrain the purpose of the ice surface condensing to ice chloride can inhibit the cond-ensate as a starting point, through the study abroad application of such technology, based on ordinary asphalt mixture Mixing salinization mixture-Verglimit-260 anticoagulant agent to dis-cuss the feasibility of ice.In this paper, ordinary asphalt mixture of ice added anticoagulant agent to form the new store salt mixture as studied through analysis of laboratory experiments to study the stability of salt to the mixture as mixing the asphalt mixture; confirm the salinization of compounds can be released; according to the technical nature of the anticoagulant agent ice analysis and special use requirements, combined with solid engineering to discuss the composition grading design, build salts obtained with the system without special asphalt mix design method, anticoagulant agent with ice can be easily mixed with France to all types of asphalt mixture mixing; detected road performance, build and test data indicated that salt mixture of pavement performance to meet regulatory requirements and construction performance; anticoagulant effect of indoor ice simulation test method, a full analysis of the feasibility.The asphalt mixture include salt of ice Research anticoagulation is not only easy to pro-duce coagulation of ice applied to the three provinces disaster areas, and can radiation to oth-er similar climate, South of China, its economic and social significance will be incalculable.
