Abstract

The invention discloses a test device for simulating acid rain corrosion of an asphalt mixture. The test device comprises a rainfall simulation box and an acid rain water supply device, the top of therainfall simulation box is provided with a rainfall simulator, a water inlet of the rainfall simulator is communicated with a water supply device through a pipeline, and the bottom surface of the rainfall simulation box is provided with a water outlet; and nozzles are arranged in the lower end face of the rainfall simulator and communicated with a water inlet of the rainfall simulator, the bottomface of the rainfall simulation box descends from the periphery to the center, a sample accommodating plate is arranged at the bottom of the rainfall simulation box in the horizontal direction, and agap is formed between the sample accommodating plate and the bottom face of the rainfall simulation box. The rainfall simulator is arranged at the top of the rainfall simulation box, the rainfall simulator is communicated with the acid rain water supply device, the sample accommodating plate is arranged in the rainfall simulation box, and a sample is placed on the sample accommodating plate, so that influence of acid rain conditions on the sample can be simulated, and a basis can be provided for evaluating the acid rain resistance degree of the asphalt mixture and improving the asphalt mixture used in areas with acid rain.

Description

technical field [0001] The invention belongs to the technical field of road engineering, in particular to a test device for simulating acid rain corrosion behavior of asphalt mixture. Background technique [0002] In the past 10 years, there have been more and more researches on the erosion and damage of concrete materials by acid rain at home and abroad. The erosive effect of acid rain. However, the current "Technical Specifications for Construction of Highway Asphalt Pavement" and "Code for Design of Highway Asphalt Pavement" have not considered the corrosion of asphalt pavement by acid rain, which shows that the corrosion of asphalt mixture by acid rain has not yet attracted enough attention. One of the reasons why the service life generally cannot reach the design period. Especially in the west of my country, the rainy season lasts for a long time, and the rainfall is large, and most of them are acid rain. The corrosion of asphalt mixture by acid rain is more prominent...
