UTAC ultrathin asphalt concrete and construction process thereof
According to the UTAC ultrathin asphalt concrete and the preparation method thereof, the UTAC ultrathin asphalt concrete is prepared from, by weight, 80-120 parts of SBS modified asphalt, 18-30 parts of modified carbon nanotubes, 20-30 parts of fine sand, 50-73 parts of coarse materials and 10-12 parts of basalt fiber, by adding metal-loaded modified single-walled carbon nanotubes, the hydration reaction of a cement-based material can be promoted, a more complete hydration product is formed, and the performance of the cement-based material is improved. The carbon nanotube modified asphalt is added into the concrete, so that the compressive strength, tensile strength and bending strength of the concrete can be improved, finally, the carbon nanotube modified asphalt can be matched with the SBS modified asphalt to improve the self-healing capability of the concrete, and when the concrete has micro-cracks, the carbon nanotube can fill the cracks and form a self-healing effect, so that the durability of the concrete is improved. And on the other hand, the basalt fibers can be matched with the modified carbon nanotubes and are wound into a rib-umbrella-shaped structure, so that the concrete is effectively compacted, and the abrasive resistance is improved.
本申请提供的一种UTAC超薄沥青混凝土及其制备方法，由下列重量份物质组成：80～120份SBS改性沥青、18～30份改性碳纳米管、20～30份细砂、50～73份粗料以及10～12份玄武岩纤维，通过添加金属负载改性单壁碳纳米管，可促进水泥基材料的水化反应，形成更完善的水化产物，进而改善混凝土的耐磨性和耐久性，添加到混凝土中还可以提高混凝土的抗压强度、抗拉强度和弯曲强度，最后，可以配合SBS改性沥青提高混凝土的自愈合能力，当混凝土发生微裂缝时，碳纳米管能够填充裂缝并形成自愈合效应，防止进一步扩大裂缝，从而提高混凝土的耐久性和使用寿命，另一方面，玄武岩纤维可配合改性碳纳米管，缠绕呈骨伞状结构，有效密实和增加耐磨强度。
