硅藻精土改性沥青混合料路用性能试验研究

Experimental Study on the Road Performance of Diatomite Modified Asphalt Mixture

硅藻精土具有多孔隙结构、比表面积大、化学稳定性强、良好的分散性等特性,对沥青路面强度和附着力的提高有一定的作用。本研究在硅藻精土改性沥青混合料路用性能的室内试验研究基础上,在江苏进行试验路段铺筑,并与普通沥青混合料路面进行比较;论证硅藻精土改性沥青混合料在江苏、安徽等华东地区推广应用的可行性。

Diatomite has the characteristics of porous structure, large specific surface area, chemical stability, and good dispersion, which would improve the strength and adhesion of the asphalt pavement. On the basis of the laboratory test of the road performance of the asphalt mixture modified by diatomite, an experiment road was built in Jiangsu Province for the comparison of the diatomite modified asphalt mixture with the ordinary asphalt mixture to discuss the feasibility of the application of diatomite modified asphalt mixture in the eastern China region such as in Jiangsu Province and Anhui Province.
