Abstract

The invention belongs to the technical field of materials for road engineering, and provides energy-saving environment-friendly asphalt which is characterized by consisting of the following components in parts by weight: 100 parts of soft asphalt, 20-35 parts of natural asphalt, 10-20 parts of biological asphalt, 5-10 parts of a diluting agent, 2-5 parts of a tackifier and 1-3 parts of a plasticizer. The invention also provides a preparation process of the energy-saving environment-friendly asphalt. The process is simple and convenient to operate, can be used for reducing the mixing temperature and is beneficial for energy conservation and environmental protection. According to the energy-saving environment-friendly asphalt provided by the invention, the high-temperature viscosity is reduced and the fluidity is improved, so that the mixing and construction temperatures are reduced by 10-20 DEG C, energy sources are saved, the discharge of polluting gases is reduced, the environmental protection performance is good, and meanwhile, the pavement performance of an asphalt mixture is improved, and the high-temperature rut resistance, low-temperature cracking resistance and water stability are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of materials used in road engineering, and in particular relates to an energy-saving and environment-friendly asphalt and a preparation process thereof. Background technique [0002] Building a resource-saving and environment-friendly society is a long-term strategic task for our country. In road construction, my country's "Twelfth Five-Year Plan for Transportation Development" regards warm-mix asphalt paving technology as a demonstration of energy-saving and emission-reduction in road construction. Promotion works. However, at present, warm mix technology at home and abroad will not only reduce the production and construction temperature of asphalt mixture, but also damage part of the road performance of the mixture to a certain extent, and the price of warm mix agent is generally expensive, and special production equipment needs to be added at the same time, which hinders its application. At the same time...
