Description
Technical field
The utility model belongs to highway maintenance field, is specifically related to a kind of permanent seal cooling cement bridge floor thin layer paving structure, is mainly applicable to cement concrete deck pavement, also may be used for each grade road cement road surface and " changes " cover in vain black.
Background technology
The application of cement concrete deck pavement technology widely, traditional method is that first making one deck bitumen macadam seal coat is used as water-proof tack coat, making two-layer SBS modified asphalt concrete layer again, cutting optimal adopts 6 ~ 10cm to be used as leveling layer and stress absorbing layer usually, upper layer adopts 4 ~ 6cm to be used as wearing layer usually, and this paving structure is thick, and cost is high, increased the weight of the carrying burden of bridge, Reflective Cracking Resistance is also not enough.Also occur first making one deck bitumen macadam seal coat in recent years and be used as water-proof tack coat, repave and build one deck about 4 ~ 6cm rubber asphalt concrete layer as stress absorbing layer and wearing layer, pave-load layer thickness is reduced greatly, but consider coefficient of sliding resistance, the traffic safety performance indexs such as construction depth, rubber asphalt concrete layer can not adopt too thin grating, thus cause Reflective Cracking Resistance still not enough, rubber asphalt poor storage stability must be processed at the scene in modification in addition, the supply of batch production finished product cannot be accomplished, small project is difficult to apply.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the permanent seal cooling cement bridge floor thin layer paving structure that a kind of pave-load layer thickness is little, cost is low, Reflective Cracking Resistance is strong.
For achieving the above object, the utility model can be achieved by the following technical programs:
A kind of permanent seal cooling cement bridge floor thin layer paving structure, comprise crushed stone sealing, asphalt concrete layer and ultra-thin wearing layer from the bottom to top, described crushed stone sealing comprises modified asphalt layer and macadam from the bottom to top, described asphalt concrete layer is the particulate formula AC-10 asphalt concrete layer adopting high-elastic modified asphalt and heat to mix heat paving technique to prepare, described ultra-thin wearing layer makes tack coat by first spreading one deck modified emulsifying asphalt, then the composite bed that the hot asphalt mixture thin layer that paves is formed.
Further, the coverage scale of described crushed stone sealing is 60%.
Further, the particle diameter of described macadam rubble is 5 ~ 10mm.
Further, described modified bitumen is high-viscosity high-elasticity SBS modified bitumen or rubber asphalt, and described modified emulsifying asphalt layer, for splitting the sticky SBS modified emulsifying asphalt of type height soon, can strengthen the bonding with old pavement, adhesion stress between raising aspect greatly, prevents road surface from peeling, passes.
Further, the thickness of described asphalt concrete layer is 2 ~ 3cm.
Further, the thickness of described ultra-thin wearing layer is 1.5 ~ 2.5cm.
Compared with prior art, the utility model has following beneficial effect:
1, have employed the SBS modified bitumen of high-viscosity high-elasticity or rubber asphalt at old pavement making synchronous surface dressing, ensure that there is stronger adhesion stress, thus extend the durability on road surface.
2, have employed the high-elastic modified asphalt with ultra-strong elasticity and stress absorbing layer made by particulate formula AC-10 dense-graded asphalt concrete, improve the ability of Reflection Cracking.
3, ultra-thin wearing layer is as surface course, not only can extend the application life on road surface, can also improve driving comfort, skid resistance, reduction noise, reduce water smoke.
Generally speaking, the utility model combines the advantage of crushed stone sealing, high-elastic modified asphalt concrete and ultra-thin wearing layer three, pave-load layer thickness is reduced greatly, reduce cost, alleviate the carrying burden of bridge, there is the ability of excellent driving comfort, safety, durability and prevention reflection crack, be specially adapted to the engineering of mating formation that cement bridge floor and cement pavement " change " cover in vain black.High-elastic modified asphalt adopts the supply of batch production finished product, is more conducive to the large-scale promotion application of this technology.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: the former road surface of 1-, 2-crushed stone sealing, 21-modified asphalt layer, 22-macadam, 3-asphalt concrete layer, 4-ultra-thin wearing layer, 41-hot asphalt mixture thin layer, 42-tack coat.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described:
As shown in Figure 1, permanent seal cooling cement bridge floor thin layer paving structure described in the utility model, comprise crushed stone sealing 2, asphalt concrete layer 3 and ultra-thin wearing layer 4 from the bottom to top, crushed stone sealing 2 is on former road surface 1.The thickness of asphalt concrete layer is 2 ~ 3cm, and the thickness of ultra-thin wearing layer is 1.5 ~ 2.5cm.Crushed stone sealing 2 comprises modified asphalt layer 21 and macadam 22 from the bottom to top.The coverage scale that crushed stone sealing is layered on road surface is 60%, and the particle diameter of rubble is 5 ~ 10mm.Asphalt concrete layer 3 is the particulate formula AC-10 asphalt concrete layers adopting high-elastic modified asphalt and heat to mix heat paving technique to prepare, ultra-thin wearing layer 4 makes tack coat 42 by first spreading one deck modified emulsifying asphalt, then the composite bed that the hot asphalt mixture thin layer 41 that paves is formed.
Preferably, modified asphalt layer 21 is high-viscosity high-elasticity SBS modified bitumen or rubber asphalt, and modified emulsifying asphalt glues SBS modified emulsifying asphalt for splitting type height soon.
