Warm-mixed SBS ultrathin wearing layer asphalt mixture mix proportion design method
The invention relates to a warm-mixed SBS ultrathin wearing layer asphalt mixture mix proportion design method, which mainly comprises the following steps: based on the stability of an asphalt mixture, selecting the material variety and mix proportion of the asphalt mixture, mineral aggregate gradation and asphalt consumption, wherein the asphalt mixture is prepared from SBS modified asphalt, aggregate and a filler, and the SBS modified asphalt is prepared from matrix asphalt, SBS, waste plastic, a copolymer of succinimide-succinate, an aminoacrylate substance and butadiene, and a peroxide. The method is designed on the basis of the stability of the asphalt mixture, overcomes the problem of instability of a general waste plastic system adopted at present, can improve the strength and toughness of the mixture, and improves the track and other damage resistance of the pavement.
本发明涉及一种温拌SBS超薄磨耗层沥青混合料配合比设计方法，主要步骤包括：基于沥青混合料的稳定性，选择沥青混合料的材料品种及配合比、矿料级配、沥青用量；沥青混合料的材料品种包括SBS改性沥青，集料和填料，SBS改性沥青的原料包括基质沥青，SBS，废塑料，丁二酰亚胺‑丁二酸酯和氨基丙烯酸酯类物质和丁二烯共聚物，过氧化物。本发明基于沥青混合料稳定性进行设计，克服当前采用通用废塑料体系不稳定的问题，还能提高混合料的强度和韧性，提高路面抵抗车辙等破损的能力。
