High-elastic salt-storage slow-release asphalt and construction method thereof
The invention discloses high-elastic salt-storage slow-release asphalt and a construction method thereof.The high-elastic salt-storage slow-release asphalt comprises an asphalt mixture, the asphalt mixture comprises tack coat oil, asphalt, stone, an anti-stripping agent, a warm mixing agent, a fiber stabilizer, an anti-freezing modifier and rubber powder, the optimal oil consumption of the asphalt mixture is 5.96%, the stone comprises coarse aggregate, fine aggregate and mineral powder, and the fine aggregate comprises coarse aggregate, fine aggregate and mineral powder. Wherein the coarse aggregate comprises rubble 1, rubble 2 and rubble 3, the particle size of the rubble 1 is 10-15 mm, the particle size of the rubble 2 is 5-10 mm, the particle size of the rubble 3 is 3-5 mm, the fine aggregate is machine-made sand, and the particle size of the machine-made sand is 0-3 mm. The asphalt mixture has the advantages that under the action of capillary pressure and vehicle rolling compaction, salt in the asphalt mixture is gradually separated out, the purpose of slowly releasing the salt is achieved, the freezing point of the road surface is reduced, rain, snow and icing on the road surface are inhibited, the freezing point of the road surface can be effectively reduced, the purposes of snow melting and deicing are achieved, the snow melting and deicing capacity is high, and the service life is long. Meanwhile, the construction method of the asphalt mixture is simple, and the manufacturing cost is low.
本发明公开了一种高弹蓄盐缓释沥青及其施工方法，包括沥青混合料，所述沥青混合料包括粘层油、沥青、石料、抗剥落剂、温拌剂、纤维稳定剂、抗凝冰改性剂和橡胶粉，所述沥青混合料的最佳用油量为5.96％，所述石料包括粗集料、细集料和矿粉，其中粗集料包括碎石1、碎石2、碎石3，碎石1的粒径为10mm‑15mm，碎石2的粒径为5mm‑10mm，碎石3的粒径为3mm‑5mm，细集料为机制砂，机制砂粒径为0mm‑3mm。本发明的优点在于，沥青混合料在毛细管压力及车辆碾压作用下，沥青混合料内部的盐分逐渐析出，达到缓释盐分的目的，从而降低道路表面的冰点，抑制道路表面雨雪结冰，可有效降低路面冰点，达到融雪和除冰的目的，融雪除冰能力强，同时本沥青混合料的施工方法简单，造价成本低。
