近年来,铺筑沥青混凝土面层的部分街道,在公共交通车站处的局部路面,一般都产生不同程度的变形,有的并已经破坏。我们于1960年和1962年曾两次进行调查,这些路面面层为单层式或双层式沥青混凝土,厚4～7厘米。自完工到目前最长者使用已九年,最近者四年,有的是完工当年即设站通行公共交通,有的是在完工七年后才增辟公共交通路线新设站位。在设站后很短时期内,停车处就都发生了变形,且逐渐发展严
In recent years, part of the streets covered with asphalt concrete pavement, local roads at public transport stations generally have varying degrees of deformation, and some have been destroyed. We conducted two surveys in 1960 and 1962. These pavement surfaces are monolayer or double-layer asphalt concrete, 4 to 7 cm thick. From the time of completion to the present, the longest one has been used for nine years. The most recent one has been used for four years. Some of them have been stationed for public transport since the completion of construction. Some have only completed new public transportation routes seven years after completion. In a very short period after the station was set up, the parking spaces were deformed and gradually developed
