我国自1978年由交通部开展阳离子乳化沥青的研究。几年来,已在14个省市铺筑各种试验路面近40余万平方米,普遍取得较好效果,至今已有8个省市进行鉴定,并在本省范围大规模推广应用。阳离子乳化沥青所以在我国能如此迅速发展,除了这种材料技术上的许多优点之外,还因有良好的经济技术效果。现就这个问题做如下简要说明。
China since 1978 by the Ministry of Communications to carry out cationic emulsified asphalt research. Over the past few years, nearly 40 million square meters of various test pavements have been paved in 14 provinces and municipalities and generally achieved good results. Up to now, eight provinces and cities have been appraised and popularized and applied in the province. Cationic emulsified asphalt so in China can be so rapid development, in addition to many of the technical advantages of this material, but also because of good economic and technical results. Now on this issue to do the following brief description.
