Abstract

The invention belongs to the technical field of road engineering, and discloses an anti-glare road sealing layer material which comprises the following raw materials in percentage by weight: 37%-52% of cationic emulsified asphalt, 35%-48% of tantalum-niobium tailings and 7%-15% of extinction resin. The extinction resin is adopted, so that the effect of reducing the glossiness of the asphalt pavement after raining can be achieved. A large number of research tests show that when the anti-dazzle road sealing layer material produced by the invention is applied to paving of an asphalt pavement, the reflectivity of the road layer is greatly reduced, and the anti-dazzle purpose is achieved, so that the safety of driving is improved.

Description

technical field [0001] The invention relates to an anti-glare road sealing material and a preparation method thereof, belonging to the technical field of road engineering. Background technique [0002] Asphalt pavement construction technology has been widely used in modern highway engineering projects in my country in recent years. The main reason is that compared with other pavement construction technologies, asphalt pavement construction technology has irreplaceable advantages. Specifically, the outstanding advantages of asphalt pavement construction technology in highway engineering construction are mainly manifested in the following aspects: First, the time cost of asphalt pavement construction technology is low. Asphalt pavement construction technology belongs to a new type of highway pavement construction technology. Compared with other pavement construction technologies, asphalt pavement construction technology only needs to pay attention to the ratio of asphalt raw m...
