Odorless high-viscosity asphalt modifier and asphalt mixture thereof

Abstract

The invention provides an odorless high-viscosity asphalt modifier. The odorless high-viscosity asphalt modifier is prepared from the following components in parts by weight: 4-7 parts of thermoplastic elastomer, 4-8 parts of rubber polymer, 5-8 parts of thermoplastic resin, 0.05-0.2 part of odor inhibitor and 0.1-0.5 part of surfactant. The invention also provides an asphalt mixture of the odorless high-viscosity asphalt modifier. According to the odorless high-viscosity asphalt modifier disclosed by the invention, the odorless high-viscosity asphalt modifier is prepared under the action of the odor inhibitor and the interfacial agent; the high-viscosity asphalt mixture is directly prepared, so that the odor in the production process of the high-viscosity asphalt mixture can be eliminated, the generation and volatilization of asphalt flue gas such as H2S, SO2 and NOX in the production and construction processes of asphalt are remarkably reduced, a remarkable odor eliminating effect isachieved, the performance of the asphalt mixture is not obviously changed, and the environmental protection and the body health of personnel are facilitated.

Description

technical field [0001] The invention relates to a clean-taste high-viscosity asphalt modifier and an asphalt mixture thereof. Background technique [0002] The permeable pavement is a pavement structure with open gradation and large void ratio. It can reduce the noise generated by vehicles when driving on the road, improve the friction coefficient when the vehicle brakes, shorten the braking distance, and reduce the road area when it rains. Water seeps into the impermeable layer below and quickly drains the water away through the shoulders, thereby reducing damage to the pavement structure caused by accumulated water. This pavement structure also reduces glare and water film on the pavement when vehicles drive at high speeds in rainy days Smooth phenomenon, improve driving safety. [0003] Permeable pavement has many advantages in practical application, but due to the special structure, the porosity of the pavement reaches about 18-25%, while the porosity of the general den...

Problems solved by technology

[0005] The existing high-viscosity asphalt mixture is modified by polymer compounding, and the asphalt viscosity is relatively high. In order to ensure the workability of the asphalt mixture, the construction temperature of the asphalt mixture is usually high, and a large amount of smoke is released during the construction process, which seriously affects the surrounding environment.

At the same time, the finished odor-cleaning high-viscosity asphalt needs to be prepared separately, and the addition of odor-cleaning agents often destroys the thermal storage stability of the finished high-viscosity asphalt, affecting the construction quality
