The middle part of fixed plate is fixedly connected with being arranged on the through hole of fixed plate with fixed block, the upper basic unit and upper equidistant set of going to a grassroots level
Preset clearance is equipped with, the preset clearance is vertically arranged with brace, and the top of the upper basic unit is fixedly installed cutting optimal, institute
The collapsible tube being provided with cutting optimal with being connected at the top of preset clearance is stated, gap filler is provided with the collapsible tube, it is described following
The top of layer is provided with waterproof layer, and one side of the waterproof layer away from cutting optimal is provided with upper layer.
Preferably, the upper layer is SMA asphalts, and the cutting optimal is AC asphalts.
Preferably, the top of the preset clearance and the upper surface flush of upper basic unit, the bottom of the preset clearance is with
The lower surface of basic unit flushes.
Preferably, the waterproof layer is FRP waterproof clothes, and the two sides of FRP waterproof clothes by asphalt adhesive respectively with above
Layer, cutting optimal connection.
Preferably, the upper basic unit is OGFC asphalts with going to a grassroots level.
The utility model proposes a kind of asphalt pavement structure suitable for high temperature difference area, beneficial effect is：Pass through
Collapsible tube is set in layer below, preset clearance is set in upper basic unit and on going to a grassroots level, and preset clearance is connected with collapsible tube,
Influence of the temperature to bituminous paving can be reduced, improve bituminous paving benefits from the life-span, solid by being set in the both sides of roadbed
Fixed board, and connected two fixed plates by brace, it can prevent the shrinkage of bituminous paving heat expansion from deforming, the utility model structure
Simply, it is easy to make, avoid road surface from being affected by temperature, effectively raise the service life of bituminous paving, while improve row
The security performance of car.
Brief description of the drawings
Fig. 1 be the utility model proposes it is a kind of suitable for high temperature difference area asphalt pavement structure structural representation.
In figure：Fixed plate 1, upper layer 2, waterproof layer 3, cutting optimal 4, upper basic unit 5, preset clearance 6, adhesive linkage 7, collapsible tube
8th, fixed block 9, brace 10,11, concrete layer 12 of going to a grassroots level, roadbed 13.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1, a kind of asphalt pavement structure suitable for high temperature difference area, including roadbed 13, the top of roadbed 13 by
