随着我国经济的发展,汽车工业得到迅速的发展,但是我们也面临着一个严峻的问题,那就是汽车的废旧轮胎的处理问题.我国每年产生的废弃轮胎大约有1400kt.废旧轮胎对环境有着严重的污染作用.因为这种材料不容易分解,需要相当长的时间.植物的生长会因之破坏,随之滋生的蚊虫也会影响人类的健康.因此,如何处理废旧轮胎成了亟待解决的问题.现在有一种工艺,可以变废为宝.那就是将废旧轮胎磨成橡胶粉,将其用于道路改性沥青当中.经实验证明,这种沥青能够改善沥青的高温与低温性能,大大降低路面的损害,同时能在很大程度上改善废旧轮胎产生的污染问题.目前,我国针对这方面的研究还不够成熟,相关的标准也不完善.%As the development of national economy, the development of auto industry is rapid, but we also face a serious problem, namely the problem of dealing with cars' scrap tires. It produces disused tires about 1400 kt in China annually. Scrap tires has severe pollution effect on the environment. Because the material is not easy to break down, needing quite a long time, the growth of plants will be damaged, thereupon, the breeding of mosquito also can affect human health. Therefore, how to deal with scrap tires becomes a problem to be solved. Taking the scrap tires ground into rubber powder and making the rubber powder applied in road modified asphalt is an effective method of dealing with above problem. By the experiment, it proves this kind of asphalt can improve the high temperature and low temperature performance of asphalt, greatly reduce the damage of the road, at the same time, it can largely improve pollution from waste tires. However, it is still not mature for the research of this aspect in our country at present, and the relevant standards is not improved.
