Electromagnetic induction enhanced nano-modified asphalt mixture with high self-healing performance as well as preparation method and application thereof
The invention provides an electromagnetic induction enhanced nano-modified asphalt mixture with high self-healing performance as well as a preparation method and application of the electromagnetic induction enhanced nano-modified asphalt mixture. The invention discloses a thermal insulation mortar which is prepared from the following raw materials in percentage by volume: 64.5%-69.1% of diabase coarse aggregate, 19.6%-24.8% of diabase fine aggregate, 2.4%-3.0% of limestone mineral powder, 0.1%-0.4% of nano silicon dioxide, 3.2%-3.8% of steel wool and 5.6%-6.4% of high-viscosity asphalt. The characteristics of the ultra-thin wearing layer of the asphalt pavement and the electromagnetic induction heating self-healing technology are combined, and the healing effect of the asphalt mixture in an electromagnetic field is effectively enhanced on the premise of ensuring the pavement performance of the ultra-thin wearing layer based on the coupling gain effect between the electromagnetic induction enhancing filler and the self-healing accelerant. According to the invention, cracks of the ultrathin wearing layer can be quickly healed in a short time, so that the effects of shortening the maintenance time and prolonging the service life of the pavement are achieved.
本发明提供了一种电磁感应增强型纳米改性高自愈合性能沥青混合料及其制备方法与应用。由如下体积分数的原料构成：64.5％～69.1％的辉绿岩粗集料、19.6％～24.8％的辉绿岩细集料、2.4％～3.0％的石灰岩矿粉、0.1％～0.4％的纳米二氧化硅、3.2％～3.8％的钢棉和5.6％～6.4％的高粘沥青。本申请结合了沥青路面超薄磨耗层和电磁感应加热自愈合技术的特点，基于电磁感应增强填料与自愈合促进剂之间的耦合增益作用，在保证超薄磨耗层路用性能的前提下，有效增强沥青混合料在电磁场中的愈合效果。本发明可以使超薄磨耗层的裂缝能够在短时间内快速愈合，从而达到缩短养护时间并延长路面使用寿命的效果。
