Abstract
The utility model relates to a road surface construction technical field especially relates to an asphalt pavement bed course structure. Comprises a regenerated asphalt mixture cushion layer, foundation soil and a reinforced concrete foundation; the foundation soil, the cushion layer and the reinforced concrete foundation are sequentially paved on the road surface from bottom to top. The utility model discloses a bituminous paving bed course structure paves on the foundation soil and rolls regeneration bituminous mixture bed course to lay reinforced concrete foundation on the bed course, the construction is simple and convenient, and regeneration bituminous mixture washes the asphalt surface layer material processing after digging by old bituminous pavement and forms, pave and can begin the ligature reinforcing bar after rolling, can accelerate the construction progress greatly, when solving original reinforced concrete structure construction, thereby must treat the problem that the ligature reinforcing bar caused the engineering period after the concrete bed course solidifies again.
Description
Technical Field
The utility model relates to a road surface construction technical field especially relates to an asphalt pavement bed course structure.
Background
In the construction of roads, since various vehicles are driven on the roads, the road surface must have sufficient mechanical strength and good stability for safe, rapid and comfortable driving of the vehicles, and the road surface must be flat and have good skid resistance, and asphalt roads are generally used for the construction of roads.
The asphalt road usually can lay the bed course earlier when the ligature reinforcing bar and guarantee the stability of reinforcing bar, and the concrete bed course is the intermediate level of reinforced concrete basis and foundation soil, and the effect makes its surfacing be convenient for ligature reinforcing bar on it, also plays the effect of protection basis, all is plain concrete, need not to add the reinforcing bar. At present when reinforced concrete structure is under construction, must wait that the concrete cushion solidifies back ligature reinforcing bar again, lead to some project that the time limit for a project is tight to appear the condition of malworking easily.
SUMMERY OF THE UTILITY MODEL
The utility model provides an asphalt pavement cushion structure for overcoming at least one defect (not enough) of the prior art.
In order to solve the technical problem, the technical scheme of the utility model as follows:
An asphalt pavement cushion structure comprises a regenerated asphalt mixture cushion, foundation soil and a reinforced concrete foundation; the foundation soil, the cushion layer and the reinforced concrete foundation are sequentially paved on the road surface from bottom to top.
Further, the regenerated asphalt mixture cushion layer is formed by processing the asphalt surface layer material after washing and planing the old asphalt pavement.
Further, the cushion layer is paved and rolled on the foundation soil.
Further, the reinforced concrete foundation is formed by pouring a reinforced bar structure and concrete.
Further, bituminous paving bed course structure is still including preventing railing and foundation ditch top escape canal, it is located reinforced concrete foundation both sides outside to prevent railing and foundation ditch top escape canal, the foundation ditch top escape canal is located prevents the railing outside.
Compared with the prior art, the utility model discloses a bituminous paving bed course structure paves on the foundation soil and rolls regeneration bituminous mixture bed course to lay reinforced concrete foundation on the bed course, the construction is simple and convenient, and regeneration bituminous mixture washes the pitch surface course material processing after digging by old bituminous pavement and forms, lay and can begin the ligature reinforcing bar after rolling, can accelerate the construction progress greatly, when solving original reinforced concrete structure construction, thereby must treat the concrete bed course and solidify the back ligature reinforcing bar again and cause the problem of engineering period.
Drawings
FIG. 1 is a structural diagram of a cushion structure of an asphalt pavement according to an embodiment of the present invention;
Wherein: 1 bed course, 2 foundation soils, 3 reinforced concrete foundations, 4 protection railings, 5 foundation ditch top escape canals, 31 steel bar structure, 32 concrete.
Detailed Description
in order to facilitate understanding of those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.
Example one
An asphalt pavement cushion structure is shown in figure 1 and comprises a regenerated asphalt mixture cushion 1, foundation soil 2 and a reinforced concrete foundation 3; the foundation soil 2 is paved with a regenerated asphalt mixture cushion layer 1, and a reinforced concrete foundation 3 is paved above the cushion layer 1. The recycled asphalt mixture cushion layer 1 is smooth in surface, so that steel bars can be conveniently bound, and the reinforced concrete foundation 3 supports the laying of an upper layer of pavement and supports the whole asphalt pavement.
In some embodiments, the reclaimed asphalt mixture mat 1 is processed from a washed and planed asphalt pavement material of an old asphalt pavement. Compared with the concrete cushion layer 1, the recycled asphalt mixture cushion layer 1 is laid on the foundation soil 2 without waiting for solidification, the steel bars can be directly bound to carry out pouring construction of the reinforced concrete foundation 3, construction is convenient and simple, construction time is greatly reduced, and the problem that a project with a tight construction period causes misoperation due to the fact that the concrete cushion layer 1 is solidified is solved.
Example two
In this embodiment, similar to the first embodiment, referring to fig. 1, the recycled asphalt mixture mat 1 is paved and rolled on the foundation soil 2, but may be paved on the foundation soil 2 by other suitable methods.
In some embodiments, the reinforced concrete foundation 3 is formed by binding a reinforcing structure 31 to the mat 1 and then pouring concrete 32.
In some embodiments, the asphalt pavement mat structure further comprises a protective railing 4 and a foundation pit top drainage ditch 5; prevent guardrail bar 4 and foundation ditch top escape canal 5 and be located 3 outer both sides on reinforced concrete basis, and foundation ditch top escape canal 5 is located and prevents the guardrail bar 4 outside. Protection railing 4 can prevent that the road surface construction from causing the harm to the external world, and foundation ditch top escape canal 5 is used for draining off water to bituminous paving bed course structure, thereby can avoid the problem that the construction condition worsens and influences the foundation bearing capacity.
During construction, firstly, the asphalt surface layer material after washing and planing the old asphalt pavement is processed to form a regenerated asphalt mixture cushion layer 1, then the cushion layer 1 is paved and rolled on foundation soil 2, after the cushion layer 1 is bound with a steel bar structure 31, concrete 32 is used for pouring to form a reinforced concrete foundation 3, and then the construction of the asphalt pavement can be completed on the reinforced concrete foundation 3.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
