二冶中心试验室为了改善多蜡沥青的性能,近三年内进行了各种试验研究,已得出初步结论:认为利用白云石废料粉作玛(王帝)脂填充料,是改善多蜡沥青性能的一条有效途径。白云石废料粉是一种硷性填料,用它配制的玛(王帝)脂,提高了软化点和后期粘结强度,表面没有裂缝。配制方法是:先将多蜡沥青在200～220℃的温度下熬制4小时(指一锅沥青500公斤沥青而言,如量
In order to improve the performance of multi-wax asphalt, the Second Metallurgical Center Laboratory conducted various experimental researches in the past three years. Preliminary conclusions have been drawn: It is believed that the use of dolomite waste powder as Ma (Wang Di) grease filler is to improve multi-wax asphalt. An effective way of performance. Dolomite waste powder is a kind of inert filler, and it can be used in the preparation of Ma (Wang Di) grease to improve the softening point and the late bond strength, the surface has no cracks. The preparation method is as follows: First, the multi-wax asphalt is baked at a temperature of 200-220° C. for 4 hours (refers to a case of a pitcher of 500 kg of asphalt, for example,
