Technical field
The utility model belongs to highway construction technical field, specifically, relates to a kind of Rut resistance and reduces the road bridge deck structure of automobile exhaust pollution.
Background technology
Along with the rapid economic development of China in recent years, the progressively increasing of infrastructure construction dynamics, based on speedway and Class I highway, the key content of Facilities Construction have also been obtained great development.Highway in China due to flexible pavement shorter for application life, the traffic volume increases severely day by day, and especially along with global air temperature warming, the number of days of hot weather gets more and more, and at present road high temperature trickling rut easily occurs remains one of disaster important in road.And increase gradually along with the recoverable amount of China's vehicle, when the bearing capacity of road also increases gradually, road asphalt is had higher requirement.And current road structure many employings plain asphalt road surface or polymer modified asphalt road surface, still can not solve the problem of road surface Rut resistance, especially in heavy traffic road surface, the problem of rut phenomenon still can not effectively be solved.
Except the rut problem on road surface, the pollution of vehicle exhaust to environment in recent years is also subject to the people's attention gradually, and according to the display of relevant department investigation result, Pekinese's haze has more than 50% to derive from pollutant in vehicle exhaust in polluting.The pollutant of vehicle exhaust mainly comprises carbon monoxide, oxynitrides, heavy metallic oxide, sulfide etc.And the most effective method of the pollution solving vehicle exhaust at present remains three-way catalyst, but still can not eliminate vehicle exhaust environmental pollution completely.Therefore, develop a kind of road surface, making it both to improve automobile pollution increases brought problem of environmental pollution year by year, also can reduce pavement track disaster, increases the service time on road surface, reduces pavement preservation maintenance period and cost, very necessary.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of Rut resistance and reduces the road bridge deck structure of automobile exhaust pollution.
