改性沥青在高速公路路面上已运用近十年时间,有成功的经验,也有不足的教训,它的优点具有较强的抗高低温稳定性,提高了路面的强度,可以有效地防止车轨和路面变形,适应大交通量路段,缺点是施工工艺要求高,造价高,摊铺温度掌握不好,容易出渗水唧浆,严重造成破损,从这几年运用情况,出现过类似的现象,如何合理运用沥青极高的改性,如何了解沥青改性后的作用,正是本文所要探讨的问题。
Modified asphalt has been used on the highway pavement for nearly ten years, with successful experience and inadequate lessons. Its advantages have strong resistance to high and low temperature stability, increased road strength, can effectively prevent the track And the deformation of the road surface to adapt to large traffic volume, the disadvantage is the high demand for the construction process, high cost, poor paving temperature control, easy to leak water slurry, causing serious damage from the use of the past few years, a similar phenomenon, How to make the best use of asphalt modified, how to understand the role of modified asphalt, it is this article to explore the issue.
