Abstract

The invention discloses a water-damage-resistant asphalt reclaimed material and a preparation method thereof, and particularly relates to the technical field of asphalt materials. The water-damage-resistant asphalt reclaimed material comprises modified asphalt, a waste asphalt mixture, a regenerant and aggregate. The aggregate comprises a mordenite molecular sieve, nano silicon carbide, hydrogel and a basalt composite material. 35.10% of the waste asphalt mixture and 6.05% of the regenerant are doped in the formula, so that the water damage resistance of the asphalt reclaimed material can be effectively improved, and meanwhile, the low temperature resistance of the asphalt reclaimed material is ensured; and the mordenite molecular sieve, the nano silicon carbide and the hydrogel can realize automatic cleaning treatment of the asphalt pavement, so that the durability of the pavement is effectively improved, the integrated contact effect of nano components in the material and other components can be effectively enhanced, the self performance of the asphalt reclaimed material is improved, the water damage resistance of the asphalt reclaimed material is improved, and the pavement durability is ensured.

Description

technical field [0001] The invention relates to the technical field of asphalt materials, and more specifically, the invention relates to a water damage-resistant asphalt reclaimed material and a preparation method thereof. Background technique [0002] With the rapid development of asphalt pavement technology, the proportion of asphalt pavement will increase. Therefore, it is very necessary to repair or rebuild these pavements in time to improve their performance. Due to the frequent overloading of highways in our country, the actual life of asphalt pavements in our country is often lower than the design life, so a large number of asphalt pavements will be produced every year to be repaired and rebuilt. In the past, the treatment of waste asphalt mixture was often simply discarded or landfilled. However, old asphalt mixture is a resource that can be recycled. If it is simply discarded or landfilled, it will not only cause waste of resources, but also It will also cause lo...
