渣油路面是否能经久耐用,一个关键性的问题,就是油路基层的稳定性和强度是否满足要求。根据我省的实践经验,渣油路面,特别是水稻田、河网地区的渣油路面的过早损坏,究其原因,首先是稳定性的问题,其次是强度问题。基层稳定性不足所造成的损坏,往往出现得早,发展得快,程度更为严重,处理更为困难。 造成基层稳定性和强度不足的原因主要有下列几种: 1.材料选择不当,例如在地下水发达的潮湿路段,使用未经处理的风化软质岩石或含泥量过大的材料,由于受水影响,岩质溶软,失去稳定,甚至造成翻浆。 2.结构不稳定。例如在采用碎石结构
Whether the residual road surface can be durable, a key issue is the stability and strength of the oil base to meet the requirements. According to the practical experience of our province, the reasons for the premature failure of the residual oil road surface in the residue road, especially in the paddy fields and in the river network are mainly the stability problem and the strength problem. Damage caused by inadequate grassroots stability often occurs early, develops rapidly, is more severe and deals with more difficulties. The main reasons for the lack of stability and strength at the grassroots level are as follows: 1. Improper selection of materials. For example, in wet sections where groundwater is developed, using unprocessed weathering soft rocks or materials with too much clay content, Affected, the rock is soft and soft, losing stability, and even causing a turbulence. 2. The structure is unstable. For example, the use of gravel structure
