1962年,前江西有色冶金建设公司在某厂锻压车间的屋面防水施工中,曾在多蜡石油沥青中掺入硫磺,以改善沥青的性能。最近对工程进行了实地调查,证实掺用硫磺的效果良好。过去我们对这种沥青的特性注意不够,只做软化点试验。软化点达到90～110℃,就认为能够满足南昌地区的气候要求。1960年曾用此种沥青,施工了两幢砖拱屋面防水层。选用玛脂配合比为:沥青80%, In 1962, the former Jiangxi Non-ferrous Metallurgical Construction Company used sulfur in the multi-wax petroleum asphalt to improve the performance of the asphalt in the roof waterproof construction of a forging plant of a certain factory. A field survey of the project has recently been conducted, confirming that the sulphur-doping effect is good. In the past, we paid insufficient attention to the properties of this asphalt, and only performed softening point tests. When the softening point reaches 90 to 110°C, it is considered that it can meet the climate requirements in Nanchang. In 1960, this bitumen was used to construct two waterproofing roofs for brick arches. The blending ratio of Margarine is 80% for asphalt.
