  要:针对目前城市非机动车道常见热熔型彩色沥青味道大,低温性能差的问题,采用环保型树脂,利用均匀试验设计方法研制了一种70号普通彩色沥青。试验结果表明,该彩色沥青各项指标满足普通70号彩色沥青的技术要求,其中软化点、10℃延度以及短期老化后指标远高于普通彩色沥青的技术要求,应用前景广阔。

Abstract:In view of the harsh and poor low performance of the hot melt type colored asphalt used in city common non motor vehicle lanes, a 70# colored bituminous was developed by the  uniform experimental method using environmental protection resin material. The results showed that the technical indicator of the developed colored bituminous met the demands of the colored asphalt specifications and the soft point and ductility was far more than ordinary colored asphalt requirements. Which  has a wide application prospect.
