高粘度基质沥青及混合料试验的思考

Consideration of High Viscosity Matrix Asphalt and Mixture Test

沥青路面和以往的水泥路面相比,其优势在于拥有很好的行车舒适性以及建设速度快以及维修便捷等等,沥青这种结构的路面已经得到了极大的应用。基于我国疆土辽阔和气候多样性以及交通条件较为复杂等等诸多因素导致了沥青路面在运营的时候会遭受不同程度的地质等的破坏,在南方地区的气候条件大多为湿热状态,对沥青路面就会产生比较严重的沥青混合料里面的高温稳定性以及水损坏病害。所以我们就要对沥青路里面的高温稳定性与抗水损害能力加以提高,这将是我们必须去解决的一个极为重要的问题。

Compared with the previous cement pavement, asphalt pavement has the advantages of good driving comfort, fast construction speed and convenient maintenance, etc. Asphalt pavement has been widely used because of its structure. Many factors such as vast territory and climate diversity and complex traffic conditions in China lead to asphalt pavement suffer varying degrees of geological damage when in operation. In the southern region, the climate conditions are mostly hot and humid state, and it will do harm to the asphalt pavement because of the damage of the high temperature stability and water damage in asphalt mixtures. So we have to improve the high temperature stability and water damage resistance of asphalt road, and it will be a very important problem to solve.
