湖北省当阳县属南方多雨地区,在沥青路面施工中,经常遇到沥青与潮湿的石料拌和裹覆不好的难题。同时还存在如何提高拌和、摊铺效率,缩短施工周期等问题。为了解决上述问题,从1985年下半年起,我们用泡沫沥青拌制沥青混合料并用于撒铺罩面的试验获得成功现介绍如下: 一、泡沫沥青混和料的生产过程泡沫沥青是一种在不外加化学添加剂的情况下,使沥青起泡沫以此达到提高沥青表面活性,提高沥青混合料质量,降低沥青消耗,使沥青混合料更易于摊铺和压实的一项低费用、高效能的油路表面处治新技
Dangyang County, Hubei Province, is a rainy area in the south, asphalt pavement construction, often encountered asphalt and wet stone mixing wrapped bad problem. At the same time, there are also problems of how to improve mixing and spreading efficiency and shorten the construction period. In order to solve the above problems, from the second half of 1985, the success of the experiment of mixing asphalt mixture with foamed asphalt and spreading the overlay is described as follows: 1. Foam Asphalt Mixture Production Process Foamed asphalt is a Foaming bitumen without chemical additives to achieve a low cost, high performance, low cost, high performance bitumen formulation that enhances bitumen surface activity, improves bitumen quality and reduces bitumen consumption, making bitumen more easily paved and compacted Surface treatment of oil new technology
