Description
Technical Field
The utility model relates to the technical field of pavement structures, in particular to a hybrid pavement structure.
Background
The asphalt base pavement is a pavement structure which is paved or arranged on a flexible base layer or a semi-rigid base layer and takes asphalt base mixture with certain thickness as a surface layer, compared with a gravel pavement structure, the pavement structure has greatly improved strength and stability, compared with a cement concrete base pavement, the asphalt pavement is flat and seamless, the driving vibration is small, the noise is low, the maintenance is simple and convenient, the pavement is suitable for being built by stages, and the asphalt base pavement structure is one of important forms of the pavement structure in China.
The existing high-grade highway generally adopts a pavement structure form of a semi-rigid base asphalt surface layer, and due to the existing heavy traffic task conditions, the whole of most of asphalt layer thickness pavements cannot reach the fatigue resistance, so that the semi-rigid base layer cracks, the service life of the road is greatly reduced, and the maintenance and repair cost of the road is increased.
SUMMERY OF THE UTILITY MODEL
The present invention aims to solve the above drawbacks and to provide a hybrid pavement structure.
In order to solve the technical problem, the utility model adopts the following technical scheme: mixed type road surface structure, including stratum basale, basic unit, the fine layer of glass, concrete layer and pitch layer, the fine layer of glass includes the fine layer of first fine layer of glass and second, concrete layer includes first concrete layer and second concrete layer, and this road surface structure is the stratum basale, basic unit, the fine layer of first glass, first concrete layer, the fine layer of second glass, second concrete layer and pitch layer from bottom to top respectively, concrete layer every interval certain distance is provided with an expansion joint, installs a plurality of pull rod in the middle of the expansion joint.
Preferably, a plurality of deceleration strips are arranged on the top surface of the asphalt layer.
Preferably, the first concrete layer and the second concrete layer have the same thickness.
Preferably, the first glass fiber layer and the second glass fiber layer have the same density.
The utility model has the following beneficial effects:
compared with the prior art, the concrete expansion joint is simple in structure, the expansion joint is reserved on the concrete layer, and the pull rod is arranged in the middle of the expansion joint, so that damage to a road caused by expansion with heat and contraction with cold can be prevented.
