Abstract


Snow icing will reduce the coefficient of friction of the ice and snow, and serious harm to affect road traffic safety problems plagued road management department, scientific and effective solution to this problem has become the focus of attention of people from all walks of life. The salinization matter since snow melting asphalt mixture is a new road surface material, the material asphalt pavement has opened up a new way to solve this problem. Salinization matter to substitute different size mineral aggregate is added directly to the mix asphalt mixture formation, due to the case of water, a salt of active ingredients with water to form a solution, the lower the freezing point of water, and thus inhibit road surface freezing and melting of the snow on the roads automatically. This article on salinization matter since snowmelt conducted a systematic study of the snowmelt mechanism of asphalt pavement and road performance. Papers by density equivalent alternative determined from snowmelt asphalt mixture salinization material dosage, experimental studies have shown that the the salinization matter since snowmelt asphalt mixture water stability, high temperature stability and low temperature crack resistance of conventional road performance can meet requirements and considerations raised in the trial process. Based on the vapor pressure of the dilute solution decreased theoretical analysis salified was to reduce the way table sleet freezing mechanism, analysis the different types salified was asphalt pavement from snowmelt action process. Focus on for salinization material self snowmelt snowmelt characteristics of the asphalt pavement, is proposed delaying frozen thin ice specimen tilting measured, snow melt, accelerated melting of the test methods to evaluate the short-term snowmelt effect, salinization of the active ingredients of natural soak dissolution and accelerate the dissolution test method to evaluate the long-term snowmelt effect, the test results show that the salinization matter since the snowmelt the asphalt mixture snowmelt performance, but its flooding under the long-term stability is somewhat less than conventional asphalt mixes. On the basis of climate partitions of asphalt and asphalt mixture, analyzed the impact of temperature, rainfall, duration and other factors on the the salinization matter precipitation, the salinization the matter since snowmelt asphalt pavement climate partition, and on this basis the a different partition salinization matter Self-snowmelt Asphalt Mixture guiding principles than design. Finally, home and abroad, salinization matter since snowmelt asphalt road paving experience, summed Salinization white snowmelt of asphalt pavement construction technology, and the salinization of the active ingredients of confirmation.
