茂名C-70彩铺胶结料性能研究

Study on road performance and technical indexes of Maoming C-70 colorized asphalt binder by experiments

从常温、高低温和耐老化性等方面对茂名C-70彩铺胶结料的基本特性进行了分析,又对其主要的技术性能指标通过试验研究,结果表明该材料可用来铺筑彩色路面。对颜料类型、添加方式和添加量等方面进行试验分析,提出了绿色、红色和黄色三种颜料的选择类型及合理的添加量为25%～30%,为进一步推广应用提供了保证。

It was studied the road performance and technical indexes emphasized on the high-temperature, low-temperature and aging resistance of Maoming C-70 colorized asphalt binder by experiments, analyzed selection of pigments, method of adding additive and additive content. It is pointed the proper pigments should be respective aluminum oxide, iron oxide red and iron oxide yellow for the color of green, red and yellow, and the optimum additive content should be 25%-30%. The results indicate that this asphalt binder can be applied into pavement construction and is adaptable for more applications.
