利用新型沥青油膜厚度计算模型,计算了砂砾式应力吸收层沥青混合料的隔离膜厚度。与传统模型计算的结果进行了对比,验证了隔离膜厚度计算模型的合理性。分别研究了矿料间隙率、矿料合成毛体积相对密度、吸收沥青用量对隔离膜厚度计算结果的影响,最后提出了砂砾式应力吸收层沥青混合料隔离膜厚度标准。 Based on the calculation model of new asphalt film thickness, the thickness of asphalt film of gravelly stress absorbing layer is calculated. Compared with the results of the traditional model, the rationality of the calculation model of the thickness of the insulation film is verified. The influences of the ratio of ore material to the voidage, the relative density of aggregate volume of synthetic wool, and the amount of absorbed asphalt on the thickness of the separator were studied respectively. Finally, the thickness standard of asphalt mixture for the gravelly stress absorbing layer was put forward.
