Abstract

The invention belongs to the technical field of pavement engineering, and particularly relates to a method for determining the design thickness of a newly-built drainage pavement. The method comprises the following steps: S10, determining a runoff coefficient range value of a newly-built drainage pavement according to the rainfall condition of an urban area; s20, designing a permeability coefficient detection model, and drawing a linear relation curve between the runoff coefficient and the pavement thickness; and S30, comparing the runoff coefficient range value and combining the linear relation curve to obtain a thickness design value of the newly-built drainage pavement. The invention aims to provide the method for determining the design thickness of the newly-built drainage pavement, and the method can effectively guide a design department to design and stipulate the thickness of the drainage asphalt pavement in a certain region, so that the construction capital is reasonably matched.

Description

technical field

[0001] The invention belongs to the technical field of pavement engineering, and in particular relates to a method for determining the design thickness of a new drainage pavement. Background technique

[0002] With the implementation of the sponge city policy, the construction of sponge cities across the country is in full swing, and the supporting technologies for sponge cities have become mature and applied on a large scale. Drainage asphalt pavement is a type of pavement paved with discontinuously graded high-viscosity asphalt mixture with a porosity as high as 18% to 25%. This kind of road surface has multiple functions of large gap, safety, noise reduction and urban heat island effect mitigation. It is an important technology in sponge city road technology and plays an important role in urban sponge city construction. For example, Shanghai's sponge city policy requires that 100% of new elevated roads use drainage asphalt pavement technology.
