沥青面层和基层的使用性能,主要是评定其强度、平整度、表面摩阻系数和渗水性等技术指标。国产沥青一般含蜡多,延度小,用以修建路面,对基层的强度及稳定性要求显得更高。公路线路长,怎样评价路面的使用性能,是个值得探讨的问题。如果对全线上百公里的路面进行技术指标的详细测定,则工作量过大,化费人力财力过多,是很不经济的。若采取以点带面的方法,则简便得多了。
Asphalt surface layer and grassroots use performance, mainly to assess its strength, flatness, surface friction coefficient and water seepage and other technical indicators. Domestic asphalt generally waxy, ductility is small, to build the road, the strength and stability of the grass-roots level is even higher. How to evaluate the serviceability of pavement is a question worth exploring. If the full range of hundreds of kilometers of the road to conduct a detailed determination of technical indicators, the workload is too large, the cost of human and financial resources too much is very uneconomical. If you take a point with the surface approach is much more convenient.
