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 concre
