Asphalt pavement structure suitable for hot areas

Abstract

The invention provides an asphalt pavement structure suitable for a hot area. The asphalt pavement structure comprises a roadbed layer, wherein a first cement macadam base layer is paved on the roadbed layer; a second cement macadam base layer is paved on the first cement macadam base layer; a plurality of hollow pipes are arranged in the second cement macadam base layer at equal intervals; a plurality of branch pipes are uniformly arranged on the outer surface of the hollow pipe; a blind plate is fixed at one end of the hollow pipe; a box body is mounted at one end, away from the blind plate,of the hollow pipe; a notch is formed in the upper portion of the face, away from the hollow pipe, of the box; an inclined filter screen is mounted on the upper side in the box body; a first L-shapedstrip and a second L-shaped strip are installed at one surface, far away from the hollow pipe, of the box body, and baffles are installed at the first L-shaped strip and the second L-shaped strip inan insertion mode. Compared with the prior art, the asphalt pavement structure has the following beneficial effects that the heat dissipation effect of an asphalt pavement is improved, the asphalt pavement is prevented from being damaged too early, and attachments on a filter screen can be conveniently cleaned.

Description

technical field [0001] The invention relates to an asphalt pavement structure suitable for hot areas, and belongs to the field of pavement technology. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. At present, in hot areas, the asphalt pavement is prone to deformation due to poor heat dissipation and has a short service life. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an asphalt pavement structure suitable for hot areas, to solve the above mentioned background technology. The short question is that the invention improves the hea...
