Heavy pavement troubles are caused for all kinds of reasons with economic development , traffic volume expanding , load increasing and channelizing traffic 随着经济发展,交通流量增大,轴载加重,以及渠化交通,路面病害加重。
As the modern highway transportation characterized with high speed , high traffic density , heavy load and channelized traffic , the technology of asphalt pavement have been changed greatly and many methods had been developed to improve the performance of asphalt pavement , such as the superpave ? , the technology of modified asphalt , the sma , etc . . among them , the fiber strengthened asphalt pavement is a successful alternative both domestically and overseas 为了适应现代交通速度快、交通密度大、轴载重、渠化交通明显的特点,沥青路面技术发生了较大的变化,高性能沥青路面superpave ~ ( tm ) 、改性沥青技术、 sma等得到了应用,而纤维沥青路面以其技术性能优良、经济上合理等特点受到人们的关注,具有广阔应用前景。
Now , there are four evaluation methods in this field , every method has its advantages and shortages and most of them are established based on highway . high weight communication , great loads channelized traffic and high speed is the expressway ' s feature , there is great difference in the development law between highway and expressway . we will get some unfitness result by using those evaluation methods to evaluate expressway 目前国内外常用的四类路面使用性能评价方法中回归法评价结果与实测数据相关性不太理想,系统分析法客观性不强,灰色理论法存在一定的主观经验性,其它一些方法还处于研究阶段;而且这些方法都是基于普通公路建立,高速公路具有交通量大、汽车轴载重、交通渠化和行车速度高等特点,路面使用性能的特点和发展变化规律与普通公路存在较大差异。
