  透层材料主要分为溶剂稀释类透层和乳化类透层,通过研究分析透层材料的发展过程,对比了煤沥青、乳化沥青、煤油稀释沥青以及高渗透乳化沥青的优缺点,指出了现有透层材料存在问题,提出:研究具有渗透功能、固结和层间粘结性能的不含溶剂类稀释剂的乳化沥青类透层油是透层材料的最佳选择,并介绍了在此基础上研发的HTC-08型透层油。

AbstractPrime coat material mainly divided into solvent dilution type prime coat and emulsion type prime coat. Researched and analysied the development process of prime coat materialscompareed the advantages and disadvantages for coal taremulsified asphaltkerosene cutback asphalt and high permeability emulsified asphaltpointed out the problems the prime coats material existing. The result showed the research direction of the prime materialresearching the prime material of emulsified asphalt which doesn’t have the solvent diluent and has the function of permeabilityconsolidation and bonding performance between layerswhich is the best choice of the prime material. The paper also introduced the HTC-08 type prime coat which R & D on the basis of the above.
