Problems solved by technology
[0005] However, the test equipment for simulating the long-term effect of automobile exhaust on pavement materials has not yet come out. The relevant test equipment at home and abroad can only provide the conditions for the degradation and absorption of automobile exhaust by materials in a closed environment in a short period of time. For example, it is impossible to simulate the long-term effect of automobile exhaust. The impact on the performance attenuation of pavement materials; the environmental conditions are closed conditions, which are quite different from the open environment where automobile exhaust affects the pavement; the temperature cannot be strictly controlled; the sunlight conditions cannot be truly simulated; the impact of rainfall on the performance of pavement materials is not simulated Device etc.

The invention provides a test device for simulating the influence of automobile exhaust on pavement materials. The test device comprises a case body, an automobile exhaust inlet pipe, an exhaust pipe, a mould fixing device, a temperature control device, a gas composition measuring device and a data processing device, wherein the case body comprises a first side surface, a second side surface, a third side surface, a fourth side surface, a bottom surface and an openable top surface in sequence; the automobile exhaust inlet pipe is arranged on the second side surface and stuck into the case body; the exhaust pipe is arranged on the fourth side surface and is higher than the automobile exhaust inlet pipe in height; the mould fixing device is arranged at the bottom of the case body so as to fix a pavement material mould on the bottom surface of the case body; the temperature control device is arranged in the case body so as to maintain and stabilize the temperature in the case body within 45 DEG C to 55 DEG C; the gas composition measuring device comprises a plurality of sensors that are vertically arranged on the inner wall of the case body in a linear way to measure the contents of gases in the case body; and the data processing device is electrically connected with the gas composition measuring device and can receive data transmitted by the gas composition measuring device so as to analyze and display the data.
Description
technical field [0001] The invention relates to a device for simulating the attenuation effect of automobile exhaust on the performance of pavement materials, and can simultaneously detect the effects of pavement materials on the absorption and degradation of automobile exhaust. Pavement materials mainly refer to asphalt and asphalt concrete materials. Background technique [0002] Vehicle exhaust is a mobile air pollution source, and the pollutants it emits mainly include: carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NO x ), particulate matter and sulfide, etc. These pollutants not only destroy the natural ecological environment and endanger human health, but also affect the durability of asphalt pavement materials, making asphalt materials aging and road performance decay. [0003] In order to solve the problem of environmental pollution caused by automobile exhaust, countries all over the world have accelerated the research work on automobile exhaust purific...
