Construction process of pavement structure of ecological cold-mixed permeable asphalt structure

Abstract

The invention discloses a construction process of a pavement structure of an ecological cold-mixed permeable asphalt structure. The process comprises the following steps: S1, cleaning and drying stones, cleaning the stones, checking whether soil remains on the surfaces of the stones or not, and drying the stones by a dryer to keep the stones dry as much as possible; S2, screening the stones, specifically, screening the sizes of the stones through a screen, and selecting the stones with a particle size of 0.5-1 cm; and S3, cleaning and checking a base layer, washing and cleaning the base layer,and waiting for the surface of the base layer to be dried. The invention relates to the construction process of the pavement structure of the ecological cold-mixed permeable asphalt structure. Cold-mixed asphalt stirred in a factory can be suitable for all-weather use, hot-mixing construction of traditional colored permeable asphalt is improved, an asphalt hot-mixing station does not need to be found any more, construction in winter does not affect strength, raw materials are easy to obtain, only a colored permeable asphalt stock solution and the stones of a set specification are needed, environment protection is facilitated, construction is simple, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of paving construction, in particular to a construction process of a pavement structure constructed of ecological cold-mixed permeable asphalt. Background technique [0002] Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate dosage and mineral aggregates of a certain grade. Asphalt concrete, as an asphalt pavement material, has to bear the repeated action of running vehicle loads and the long-term impact of environmental factors during its use. Therefore, while asphalt concrete has a certain bearing capacity, it must also have good durability against natural factors. That is to say, it should be able to show sufficient stability in high temperature environment, crack resistance in low temperature condition, good water stability, long-lasting anti-aging an...

Problems solved by technology

That is to say, it should be able to show sufficient stability in high temperature environment, crack resistance in low temperature condition, good water stability, long-lasting anti-aging and good anti-skid property to ensure asphalt pavement Good service function, but the traditional asphalt construction needs to find an asphalt hot mixing station, the winter construction affects the strength, the operation steps are more cumbersome, and the asphalt laying work cannot be completed simply and conveniently
