Abstract

The invention provides a bionic self-healing asphalt modifier and a preparation method thereof. The bionic self-healing asphalt modifier comprises a self-healing component and an anti-stripping component. The material with expansibility and autonomous multiplication and crystallization properties at a normal temperature serves as the self-healing component and is combined with a common anti-stripping component in the field, and a human body healing mechanism is simulated, so that the modified asphalt material enables the road to have an autonomous healing function similar to the human body on the premise of not influencing the paving performance, pavement or subgrade cracks can be effectively filled, damage of rainwater on the subgrade is reduced, and the service life of the pavement is prolonged. The bionic self-healing asphalt modifier is simple in process, convenient to operate, pollution-free in preparation process and low in cost.

Description

technical field [0001] The invention relates to the technical field of road and building material modification, and more specifically, to a bionic self-healing asphalt modifier and a preparation method thereof. Background technique [0002] The construction of transportation infrastructure is the cornerstone of national development. As of 2016, the total mileage of my country's highways has reached 4.57 million kilometers, and urban roads account for 1 / 3 of the total urban area. Nearly 200,000 kilometers of roads need to be restored and reconstructed every year. The frequent occurrence of road diseases leads to huge investment in road maintenance, and at the same time has a major impact on traffic safety and people's travel. The problem of road maintenance has attracted widespread attention at home and abroad. In some areas with heavy traffic pressure, it is of great significance to build durable and long-life roads. [0003] According to research, road cracks are not only ...
