我们射阳公路站共养护50公里油路,除其中2.6公里铺筑4年外,其它均在9年以上,属超期服役。以主要干线岗合线为例,射阳境内长32.43公里,基层为石灰土,厚16厘米;面层为沥青表处,厚2.5厘米。1977年和1978年两年内铺筑完毕,已超过设计使用寿命近一倍。其间没搞过大修,中修里程也少,致使目前的状况是:路面网裂、基层部分变形的有约3公里;路面网裂、基层部分有裂缝但尚未变形的有约10公里,喷油加砂后形成光面或局部
We Sheyang Road Station to maintain a total of 50 kilometers of oil, in addition to which 2.6 km paving 4 years, others are more than 9 years, is an extended service. In the main trunk line with an example, Sheyang territory of 32.43 kilometers long, the grass-roots limestone, 16 cm thick; surface of the asphalt table, 2.5 cm thick. Paving completed in 1977 and 1978 within two years, has nearly double the design life. In the meantime, there was no major overhaul in the repair mileage is also less, resulting in the current situation is: cracked pavement, the grassroots part of the deformation of about 3 km; pavement crack, the grassroots part of the crack but not deformed about 10 km, fuel injection After adding sand to form a glossy or local
