[0027] The present invention also provides a method for preparing the above-mentioned clean-taste high-viscosity asphalt composition, the steps are as follows:

[0028] (1) Accurately weigh 80-88 parts of asphalt and heat to 130-140°C, add 0.2-1 part of surfactant under stirring at 100-150r / min, and stir for 15-20 minutes;

[0029] (2) Heat the mixture obtained in step (1) to 160-175°C, add a high-viscosity modifier to swell, add 0.2-2 parts of an odor inhibitor, and 0.2-0.5 parts of a stabilizer, and turn on the shearing device to cut 40- 60min, and then put it into an oven to develop for 1h, and the clean-taste high-viscosity asphalt composition is prepared.

Embodiment 1

[0032]Weigh 88 parts of asphalt by weight, heat to 140°C, add 1 part of surfactant under stirring at 150r / min, and stir for 20 minutes; raise the temperature to 160°C, add 15 parts of high-viscosity modifier to swell for 30 minutes, add odor suppression 1.5 parts of agent and 0.5 parts of stabilizer, the shearing device was turned on to shear for 40 minutes, and then put into an oven to develop for 1 hour, that is, the clean odor high viscosity asphalt composition was prepared.

Embodiment 2

[0034] Weigh 80 parts of asphalt by weight, heat to 130°C, add 0.2 parts of surfactant under stirring at 150r / min, stir for 15 minutes; heat up to 160°C, add 12 parts of high viscosity modifier to swell for 30 minutes, add odor suppression Add 0.8 parts of stabilizer and 0.2 parts of stabilizer, turn on the shearing device to shear for 40 minutes, and then put it in an oven to develop for 1 hour, that is to say, the conventional technical indicators of the clean-flavored high-viscosity asphalt composition are prepared in Table 2.

Abstract

The invention provides an odor-free high-viscosity asphalt composition for a water permeable pavement. The asphalt composition is prepared from the following components in parts by weight: 80-88 partsof asphalt, 12-15 parts of a high-viscosity modifier, 0.2-2 parts of an odor inhibitor, 0.2-1 part of an interface activating agent and 0.2-0.5 part of a stabilizing agent. According to the odor-freehigh-viscosity asphalt composition provided by the invention, the generation and volatilization of the asphalt gas such as H2S, SO2, NOx and the like in asphalt production and construction processescan be reduced through the action of the odor inhibitor and the interface activating agent, so that a remarkable odor removal effect is achieved, the asphalt performance does not change obviously, andthe environmental protection and health of personnel are facilitated. The invention also provides a preparation method of the odor-free high-viscosity asphalt composition.

Description

technical field [0001] The invention belongs to the field of road engineering materials, and in particular relates to a clean-odor high-viscosity asphalt composition for water-permeable road surfaces and a preparation method 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...
