我国援马达加斯加2号公路已完满竣工.该路位于马国东部,气候、水文、工程地质条件十分恶劣.气温很高,水量很大,年降雨量可达400毫米以上,降雨天数占全年的三分之二以上.风化的高含水量残积粘性土给路基施工造成了极大的困难.过分湿热的气候条件也给沥青路面施工及其质量带来了极不利的影响.2号公路的胜利建成,其质量优良,积累了丰富的湿热地区筑路经验,为我国赢得了信誉.笔者有幸参加了河北省承建的援马工程的部分技术工作,愿就该工程如何解决湿热地区沥青混合料热稳性,提高其抗水剥蚀能力的问题
Our road to Madagascar, No. 2, has been completed satisfactorily. The road is located in the eastern part of the country and its climate, hydrology and engineering geological conditions are very harsh. The temperature is very high and the amount of water is very large. The annual rainfall can reach 400 mm and the number of rainfall days in the whole year More than two thirds of the weathering of high water content of residual clay to the construction of roadbed caused great difficulties.Excessively hot and humid climatic conditions also have a very adverse impact on asphalt pavement construction and its quality.Victory on Highway 2 Built, its good quality, has accumulated rich experience in road construction in hot and humid areas, won the credibility of our country.I was fortunate enough to participate in the construction of Hebei Province, some of the technical assistance work, willing to work on how to solve the project hot and humid asphalt mixture heat Stability, improve its ability to resist water erosion problems
