In this study, the asphalt mixture (porosity <2%) was tested for use between the upper and middle layers of the asphalt pavement to improve its interlayer structure and to enhance its related waterproof and anti-cracking ability.
Considering the weather characteristics and traffic conditions in Jiangxi Province, appropriate raw materials were selected. Based on the technical indexes of the raw materials, expected porosity (<2%), and AC-5 standard for the asphalt mixture, experiments were conducted to determine the best gradation range of the waterproof and anti-cracking layer, and to obtain the optimum amount of the asphalt and fiber used based on Marshall tests.
The high-temperature rutting test, low-temperature cracking test, and water stability test were conducted to evaluate the pavement performance of the waterproof and anti-cracking layer.
A waterproof and anti-cracking layer was added between the upper and middle layers of the asphalt pavement, which has excellent performance for avoiding cracks and water damage.
在本研究中，对孔隙率小于2%的沥青混合料进行了测试，以用于沥青路面的上层和中层之间，改善其层间结构并增强其相关的防水和抗裂能力。
考虑江西省的气候特征和交通条件，选择了合适的原材料。基于原材料的技术指标、预期孔隙率（小于2%）以及沥青混合料的AC-5标准，进行试验以确定防水抗裂层的最佳级配范围，并通过马歇尔试验获得沥青和纤维的最佳用量。
进行了高温车辙试验、低温抗裂试验和水稳定性试验，以评估防水抗裂层的路面性能。
在沥青路面的上层和中层之间添加了防水抗裂层，该层在避免裂缝和水损害方面具有优异性能。
