摘要
利用化学反应推导方法探讨酸雨对沥青路面的化学破坏作用 ,得出了沥青路面中的矿料与酸雨中的酸性物质硫酸和硝酸等发生化学反应的方程式 ,发现酸雨中的酸性物质与沥青混合料中的酸性和碱性矿料反应都会生成可溶于水的盐类 。
The chemical corrosion effects tha t the acid rain would bring to the asphalt pavement are studied by chemical reac tion i nference. The chemical reaction equations between the acid rain and the alkali a g gregates and the acid aggregates in asphalt mixtures are deduced in the paper. T he results indicate that the chemical reactions between the acid rain and the aggr egates can produce salinities that are easy to dissolve in water. Apparently the chemical corrosion of the acid rain to asphalt mixtures can accelerate the earl y moisture damage of asphalt pavements.
