Abstract

The invention relates to an anti-ultraviolet nanometer rare earth composite graphene oxide modified emulsified asphalt and a preparation method thereof. The emulsified asphalt comprises a main material and an auxiliary material, wherein the main material comprises, by weight, 50-80% of heavy oil asphalt and 20-50% of water, and the auxiliary material comprises (calculated as the weight of the main material) 0.1-1% of a nanometer rare earth oxide, 0.1-1% of graphene, and 1-4% of an emulsifier. The preparation method comprises: heating water, adding an auxiliary material comprising a nanometer rare earth oxide, graphene oxide and an emulsifier, uniformly stirring to obtain a, and pouring the a in the case of stirring of heavy oil asphalt with an emulsification mill to obtain the modified emulsified asphalt. According to the present invention, the obtained modified emulsified asphalt has advantages of good ultraviolet resistance and good weather resistance, and is suitable for the pavement maintenance in alpine and high ultraviolet radiation environments.

Description

technical field [0001] The invention relates to a pavement maintenance asphalt material used in high-cold and high-ultraviolet irradiation environments and a preparation method thereof, in particular to an anti-ultraviolet nanometer rare earth composite graphene oxide modified emulsified asphalt and a preparation method thereof, belonging to the technical field of road materials. Background technique [0002] In recent years, with the rapid development of my country's transportation industry, the traffic volume is increasing day by day, and the highway construction is also developing at a fast pace. The asphalt pavement bears the multiple effects of huge traffic load and natural environmental factors, so higher and higher requirements are put forward for the quality of its road materials. During the service period, asphalt pavement affects the performance of the pavement due to aging, resulting in insufficient durability, which shortens the service life of the asphalt paveme...
