排水性沥青混凝土路面以其安全降噪的优点在国内外得到广泛应用,但其大空隙的特点,导致其易被飘尘、泥沙等杂物堵塞而产生功能衰减。通过一种国产排水性沥青混凝土路面恢复车对堵塞路面进行清洗养护,分析该机能恢复车的清洗效果并提出了预养护的重要性。清洗结果表明,国产排水性沥青混凝土路面恢复车无论对于浅层或深层堵塞都有明显的清洗效果,能在很大程度上恢复排水性沥青混凝土路面的排水功能。
Drainage asphalt pavement is widely used both at home and abroad due to its safety and noise reduction. However, the characteristics of its large voids lead to its function being easily clogged by dust, silt and other debris. Through a kind of domestic drainage asphalt concrete pavement restoration vehicle, the blockage road surface was cleaned and maintained. The function of the vehicle recovery car was analyzed and the importance of pre-curing was put forward. The results of cleaning show that domestic drainage asphalt concrete pavement recovery car has obvious cleaning effect both for shallow and deep blockage and can largely restore the drainage function of drainage asphalt concrete pavement.
