我专区在1964年6月开始做渣油路试验(修了2.6公里试验路),1965年在几个县、市进行扩大试验,总计修了13公里。通过两年来的实践证明,利用渣油做表面处治基本是成功的,也是经济有效的,是今后改善路面技术状况的重要途径。这一试验是在干旱、多风的被称做“八百里早海”上进行的,现介绍如下: (一)原路面的调查和处理我们首先在白城——平台公路进行试验。1965年5月下旬对原有路基路面的技术状况进行勘测。该
My prefecture began to do the residue road test in June 1964 (a 2.6-km trial road). In 1965, it expanded its tests in several counties and cities, totaling 13 kilometers. After two years of practice, it has been proved that the use of residual oil for surface treatment is basically successful and economical, which is an important way to improve the technical condition of pavement in the future. This experiment was conducted in arid and windy area called “Eight Mile Early Sea” and is described as follows: (I) Investigation and Handling of Original Pavement We first conducted a trial on the Baicheng-Platform Road. In late May 1965, the technical condition of the original subgrade and pavement was surveyed. This
