前言：关于沥青路面早期病害的学术文章或专著做为公路人，我们大家看过或了解的已经很多，按理说一般情况下应该通车后不会或很少出现早期病害，但实际情况并非如此，全国范围内关于路面通车后路面早期病害严重的报导每年都有较多篇幅见诸相关报纸或网站，本文针对XXXX施工实际情况就“己往多被施工等忽视或容易处理不好”的几个施工中实际“可能对通车后路面造成早期限路面病害”的问题进行分析和探讨，以便引起公路同行及相关部门的重视和注意。
沥青各结构层施工期间路面污染问题
中、下面层施工完成段，在没有进行其上一层沥青路面铺筑前被污染往往是不可避免的，大多已司空见惯，往往在多次制止但却在效果较差的情况下顺其自然了。污染原因为：
1、公路沿线途经村落道口行人或车辆横穿
Abstract The pollution of road construction, through the layer, under the seal layer, adhesive layer on the asphalt layer of the impact of oil stone, bridge surface (including slab) the impact of the quality of the asphalt pavement, subgrade differential settlement of the road impact issues Discussion and analysis of their disease on the impact of the early road to remind road construction and related sectors who attach great importance to ensure the quality of asphalt pavement construction
Keywords pollution through the asphalt pavement, sealing, adhesive layer of oil stone slab bridge road surface crack fracture uneven settlement of Subgrade
Background: Early Disease on the asphalt pavement of academic articles and monographs as a road, we all have seen or know a lot, presumably after the opening under normal circumstances should be little or no presence of early disease, but it is not the case, throughout the country on the road surface after the opening of the early reports of serious disease every year, more coverage seen in the relevant newspaper or Web site, the actual construction of this paper XXXX Qingkuang on "had to be construction and so much easier to deal with neglected or bad" of several Actual construction "could result in early period after the opening of the road surface disease" analysis and discussion of issues in order to cause highway counterparts and relevant departments of the importance and attention.
During the construction of each layer of asphalt pavement pollution
, The following paragraph completion of the construction layer, in the absence of conduct on which a layer of asphalt pavement is often contaminated before paving is inevitable, many of whom have become commonplace, often several times less effective to stop it in case of go with the flow of. Pollution because:
