Description

Resin composite modified high-viscosity asphalt pavement

Technical Field

The utility model relates to a bituminous paving technical field specifically is a resin composite modification hyperviscosity asphalt pavement.

Background

Asphalt pavement is characterized by that it is a mineral material mixed with various kinds of pavement paved with asphalt material, and the asphalt binder can raise the resistance of paving granules to running and damage of natural factors to pavement, and can make the pavement smooth, dustless, impervious and durable, so that it is a high-grade pavement which is most extensively used in road construction.

Because most of current bituminous paving compressive capacity is not enough under the horizontal load effect, after using a period, the highway section that the vehicle flow is big, the speed of a motor vehicle is slow and brake more easily produces and passes the hug, reduces the road surface roughness, and rainy day road surface ponding can lead to the vehicle tire to skid, influences the normal driving of vehicle.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a resin composite modification hyperviscosity asphalt pavement to solve the easy problem of producing the lapse of advocacy package that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high viscous asphalt pavement of resin composite modification, includes thin pitch layer, the bottom on thin pitch layer is provided with thick pitch layer, the inside on thin pitch layer is provided with the fixed plate, the equal fixedly connected with stopper in both sides of fixed plate, the spacing groove has been seted up to the stopper, the both sides of fixed plate all are provided with the wire netting, the both sides of wire netting all with spacing groove looks adaptation.

Further, the bottom of fixed plate runs through thin pitch layer and extends to the inside on thick pitch layer, the bottom fixedly connected with base of fixed plate, the equal fixedly connected with inserted bar in both sides of base bottom.

Furthermore, a plurality of protective grooves are formed in the top of the fine asphalt layer, and water leakage grooves are formed in the bottom of the protective grooves.

Furthermore, the bottom of the water leakage groove penetrates through the fine asphalt layer and extends to the inside of the coarse asphalt layer.

Furthermore, a concrete base layer is arranged at the bottom of the coarse asphalt layer, a broken stone cushion layer is arranged at the bottom of the concrete base layer, and a rammer layer is arranged at the bottom of the broken stone cushion layer.

Compared with the prior art, the beneficial effects of the utility model are that: the resin composite modified high-viscosity asphalt pavement is reasonable and has the following advantages:

(1) The fixed plates and the wire nets are arranged inside the fine asphalt layer and the coarse asphalt layer, the fixed plates and the wire nets are matched with each other to increase the tension of the asphalt pavement, the base and the inserted rods are arranged at the bottom of the fixed plates to enhance the tensile degree, and the traction is not easy to be generated during the driving load, most of the traditional asphalt pavements have insufficient compressive capacity under the action of horizontal load, and after the asphalt pavement is used for a period of time, the road sections with large traffic flow and slow vehicle speed are easy to generate traction upheaval and reduce the pavement evenness;

(2) The top of the fine asphalt layer is provided with a plurality of protective grooves, the traditional asphalt pavement can gradually become hard and begin to shrink when the air temperature is greatly reduced, cracks are easy to generate, the asphalt pavement is dried under insolation in summer at high temperature, and the protective grooves can ensure that the asphalt pavement has good stress relaxation performance under the condition of higher temperature or lower temperature, so that the pavement cracking phenomenon caused by expansion with heat and contraction with cold is prevented;

(3) The inside on thin pitch layer and thick pitch layer is provided with the water leakage groove, and the water leakage groove can make the quick infiltration ground end of ponding on road surface, and traditional bituminous paving receives the repeated action of traffic load and temperature harmomegathus under the circumstances that has moisture in rainy day ponding etc. moisture infiltration, and moisture infiltration just because the effect of water power, and the bonding force between the bituminous paving loses and can lead to the road surface to destroy, and because surface ponding, very easily take place automobile tire and skid drift etc. and lead to the traffic accident, the utility model discloses this problem of solution that can be fine.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: the utility model provides a resin composite modification hyperviscosity asphalt pavement, includes thin pitch layer 1, its characterized in that: the bottom on thin pitch layer 1 is provided with thick pitch layer 2, the inside on thin pitch layer 1 is provided with fixed plate 7, the equal fixedly connected with stopper 10 in both sides of fixed plate 7, the spacing groove has been seted up to stopper 10, the both sides of fixed plate 7 all are provided with wire netting 8, wire netting 8's both sides all with spacing groove looks adaptation.

The bottom of fixed plate 7 runs through thin pitch layer 1 and extends to the inside on thick pitch layer 2, the bottom fixedly connected with base 11 of fixed plate 7, the equal fixedly connected with inserted bar 12 in both sides of base 11 bottom can strengthen the tensile degree, is difficult to produce when the driving load and passes.

A plurality of protection grooves 6 are formed in the top of the fine asphalt layer 1, water leakage grooves 9 are formed in the bottoms of the protection grooves 6, accumulated water on the road surface can rapidly penetrate into the ground bottom through the water leakage grooves 9, and traffic accidents caused by slipping and drifting of automobile tires due to the accumulated water on the road surface are prevented.

The bottom of the water leakage groove 9 penetrates through the fine asphalt layer 1 and extends to the inside of the coarse asphalt layer 2.
