Abstract
The utility model discloses a stress absorbing layer bituminous pavement structure relates to the bituminous highway for solve the abominable and great highway section of traffic load of climatic conditions, the road surface is harmd seriously, the poor problem of the durability of highway engineering. Surface course, buffer layer, upper base layer, well basic unit and underlayment including top -down, the buffer layer includes the shock attenuation container, is located the damping spring of shock attenuation container the inside, shock attenuation upper cover and shock attenuation lower cover, damping spring connects upper base layer through shock attenuation cover connection surface course, its lower extreme through the shock attenuation lower cover in the upper end. Through providing an exclusive buffer layer, avoid the abominable and great highway section of traffic load of climatic conditions, the road surface damage appears, improve the durability of highway engineering.
Description
Technical field
This utility model relates to bituminous highway, specifically, is a kind of stress absorbing layer asphalt pavement structure.
Background technology
Bituminous highway career development is very fast, but generally there is technology and the problem of two aspects of quality in bituminous paving, it is mainly reflected in the durability of highway engineering and the Random early Detection on road surface, especially in the section that some weather conditions are severe and traffic loading is bigger, therefore, the performance of bituminous concrete is had higher requirement.
Patent documentation CN204898456U (applying date: 2015.09.02) discloses a kind of stress absorbing layer bituminous paving Han rubber asphalt, including the stress absorbing layer laid the most successively, cutting optimal, adhesion coating and upper layer；Described stress absorbing layer is layed in Cement Concrete Pavement Slab, described stress absorbing layer is rubber asphalt stress absorbing layer, described upper layer is OGFC-13 open gradation asphalt, and described adhesion coating is double-deck SBS modified emulsifying asphalt layer, and described cutting optimal is AC-13 asphalt layer.This utility model has dewatering and noise reduction antiskid performance, reduces road surface Moisture Damage, reduces traffic noise, improves driving safety and comfortableness, additionally it is possible to preferably bear the traffic pressure grown with each passing day, and extends the service life of road.
But technique scheme has the following disadvantages, the section that weather conditions are severe and traffic loading is bigger, pavement damage is serious, the poor durability of highway engineering.
Utility model content
This utility model purpose is intended to provide the stress absorbing layer asphalt pavement structure of a kind of durability improving highway engineering.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of stress absorbing layer asphalt pavement structure, including top-down surface layer, cushion, upper basic unit, middle basic unit and underlayment, described cushion includes damping container, it is positioned at the damping spring of damping receptacle, damping upper cover and damping lower cover, damping top cap junction layer is passed through in described damping spring upper end, and its lower end connects upper basic unit by damping lower cover.
The utility model of employing technique scheme, first, in the section that traffic loading is bigger, damping spring is installed, improves the durability of highway engineering；Second, damping spring is placed on damping receptacle, it is to avoid damping spring is corroded.
Limiting further, described underlayment is rubble and weak soil mixes, and described middle basic unit is cement and fine sand mixes, and described upper basic unit is burnishing surface, and described surface layer uses drought resisting Colophonium.
On the one hand, cement and the fine sand of middle basic unit uses after-pouring, it is simple to site operation, on the other hand, uses the upper basic unit of polishing, the linking degree of basic unit and surface layer in raising, it is to avoid crack occurs in long term high temperature Exposure to Sunlight.
Limit further, described damping container height 6-8cm.
The damping Vessel Design of exclusive high 6-8cm, improves the structural strength on road surface, rigidity and stability.
This utility model compared to existing technology, simple in construction, cost-effective.
Accompanying drawing explanation
This utility model can be further illustrated by the nonlimiting examples that accompanying drawing is given；
Fig. 1 is this utility model one modified asphalt mixture road surface schematic diagram；
Fig. 2 is the partial enlarged drawing of A in Fig. 1；
Main element symbol description is as follows:
Surface layer 1, cushion 2, upper basic unit 3, middle basic unit 4, underlayment 5, damping container 6, damping upper cover 7, damping lower cover 8, damping spring 9.
Detailed description of the invention
In order to make those skilled in the art that this utility model be may be better understood, with embodiment, technical solutions of the utility model are further illustrated below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in Fig. 2, a kind of stress absorbing layer asphalt pavement structure, including top-down surface layer 1, cushion 2, upper basic unit 3, middle basic unit 4 and underlayment 5, cushion 2 includes damping container 6, is positioned at the damping spring 9 inside damping container 6, damping upper cover 7 and damping lower cover 8, damping spring 9 upper end connects surface layer 1 by damping upper cover 7, and its lower end connects upper basic unit 3 by damping lower cover 8.
It should be noted that damping container 6 upper and lower side inwall is provided with female thread (diagram is not drawn into), damping upper cover 7 and damping lower cover 8 outer wall is equipped with external screw thread (diagram is not drawn into), utilize threaded easy installation and removal.
In preferred embodiment, underlayment 5 mixes for rubble and weak soil, and middle basic unit 4 mixes for cement and fine sand, and upper basic unit 3 is burnishing surface, and surface layer 1 uses drought resisting Colophonium.
The high 6cm of damping container 6.
A kind of stress absorbing layer asphalt pavement structure provided this utility model above is described in detail.The explanation of specific embodiment is only intended to help to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; on the premise of without departing from this utility model principle, it is also possible to this utility model is carried out some improvement and modification, these improve and modification also falls in this utility model scope of the claims.
