Problems solved by technology

[0003] In the prior art, there are many disadvantages to the traditional asphalt pavement. Regardless of whether the pavement base is flexible or semi-rigid, cracks of varying degrees will appear on the asphalt pavement during use. At the same time, the pavement surface is partially loose and forms grooves, which seriously affects driving. Safety

Abstract

The invention discloses an asphalt pavement with a water conserving function in a severe cold area. The pavement has the advantages that the novel water-conserving asphalt pavement can rapidly absorb pavement water, water accumulated on a road surface can infiltrate downwards, the water-drift phenomenon of driving vehicles on a road is avoided, the contact area between the pavement and tires is greatly increased, antiskid performance is improved, and traffic accidents on rainy days are reduced by about 80%; the temperature of the water-conserving asphalt pavement is reduced through repeated water absorption and evaporation water loss, then the solar radiation absorption efficiency of the asphalt pavement is improved, and the urban temperature can be lowered as a whole; the water-conserving asphalt pavement has large pores, due to the pores, the pavement has a certain effect on reducing noise, expenditures on road repairing are saved, raw material waste is reduced for enterprise production, and the pavement conforms to the environment protection concept.

Description

technical field [0001] The invention relates to the field of asphalt preparation methods, in particular to an asphalt pavement with water retention function in severe cold regions. Background technique [0002] Asphalt pavement refers to various types of road surfaces that are paved with asphalt materials mixed with mineral materials. Asphalt binders improve the ability of paving aggregates to resist damage to the road surface caused by driving and natural factors, making the road surface smooth and less dusty. Permeable and durable, therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but its base layer can also use rigid materials in addition to flexible materials. Cement concrete, or a semi-rigid hydraulic material. [0003] In the prior art, there are many disadvantages to the traditional asphalt pavement. Regardless of whether t...
