Abstract

The invention discloses environment-friendly composite modified emulsified asphalt and a preparation method thereof, and aims to solve the technical problem that the existing modified emulsified asphalt is insufficient in environmental protection efficiency and pavement performance. The modified asphalt is mainly prepared from emulsified asphalt, tetrabutyl titanate, nitric acid or urea, cobalt nitrate, nano graphene nanoplatelets, cationic styrene-butadiene latex, a thickener, a stabilizer and the like. The environment-friendly composite modified emulsified asphalt is good in cracking resistance, high-temperature resistance, rut deformation resistance, water stability and skid resistance when being applied to road asphalt pavements, and normal use of roads is guaranteed; under the action of sunlight, a photocatalytic reaction in the composite modified emulsified asphalt has a tail gas purification function.

Description

technical field [0001] The invention relates to the technical field of road engineering materials, in particular to an environment-friendly composite modified emulsified asphalt and a preparation method thereof. Background technique [0002] The composition of automobile exhaust is very complex, and its main pollutants include carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOX), as well as some other solid particles that have adverse effects on the human body. Pollution from vehicle exhaust poses a serious threat to human health. With the sharp increase in the number of automobiles in my country, the problem of environmental pollution caused by exhaust emissions is becoming more and more serious. Therefore, the development and research of effective exhaust gas treatment methods can solve this practical problem, do a good job in air pollution prevention and control, and improve air quality. significant. [0003] At present, most of the treatment and purificatio...
