用硫磺代替部分结合料有许多优点已为大家公认。在硫磺过剩的国家,用它来代替昂贵的石油低级产物是有经济效益的。此外,当拌和及摊铺时,其和易性显著增加,以至可能获得较好的压实度。在重复交通荷载作用下,抗变形是沥青路面面层的一种重要特性,它受到集料颗粒之间的摩阻力及沥青结合料的性能的影响。在混合料中掺入硫磺是为了保持拌和的温度
There are many advantages to replacing part of the binder with sulfur and are well known to all. In countries with excess sulfur, it is economically viable to use it instead of expensive low-grade petroleum products. In addition, the workability is significantly increased when mixing and spreading, so that a better degree of compaction may be obtained. Anti-deformation is an important property of asphalt pavement under repeated traffic load. It is affected by the frictional resistance between aggregate particles and the properties of asphalt binder. Sulfur is added to the mix to maintain the mixing temperature
