Description
Technical field
The utility model belongs to highway maintenance field, is specifically related to a kind of energy-saving 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 6cm ~ 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 be to provide that a kind of pave-load layer thickness is little, cost is low, Reflection Cracking and the strong energy-saving cement bridge floor thin layer paving structure of waterproof ability.
For achieving the above object, the utility model can be achieved by the following technical programs:
A kind of energy-saving cement bridge floor thin layer paving structure, comprise crushed stone sealing, asphalt concrete layer and super sticky 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, and described super sticky wearing layer is the super sticky Cold-mix layer that one deck is mixed into fiber.
Further, the coverage scale of described crushed stone sealing is 60%.
Further, the particle diameter of described macadam medium stone is 5 ~ 10mm.
Further, described modified asphalt layer is high-viscosity high-elasticity SBS modified bitumen or rubber asphalt, 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 super sticky wearing layer is 0.8 ~ 1.0cm.
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, super sticky wearing layer is as surface course, not only can extend the application life on road surface, can also improve the abrasion performance on road surface, skid resistance, water proofing property and safety.
Generally speaking, the utility model combines the advantage of crushed stone sealing, high-elastic modified asphalt concrete and super sticky 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 safety, durability, skid resistance, water proofing property 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.
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, the super sticky wearing layer of 4-.
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, cement bridge floor thin layer paving structure described in the utility model, comprise crushed stone sealing 2, asphalt concrete layer 3 and super sticky 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 super sticky wearing layer is 0.8 ~ 1.0cm.Crushed stone sealing 2 comprises modified asphalt layer 21 and macadam 22 from the bottom to top.The coverage scale that crushed stone sealing 2 is layered on road surface is 60%, and the particle diameter of macadam 22 medium stone 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, and super sticky wearing layer 4 is mixed into the super sticky Cold-mix layer of fiber for one deck.
Preferably, modified asphalt layer 21 is high-viscosity high-elasticity SBS modified bitumen or rubber asphalt.
The laying step of energy-saving cement bridge floor thin layer paving structure described in the utility model is as follows:
1, carries out prospecting to original road surface before construction to assess, select the material of modified bitumen and consumption as the binding material of crushed stone sealing 2 as requested;
2, close traffic, cleans original road surface;
3, first spreading one deck heated bitumen sticking layer oil, then spreading one deck particle diameter is the rubble of 5 ~ 10mm, the coverage scale of rubble is 60%;
4, with paver placement thickness be the AC-10 bituminous mixture stress absorbing layer of 2 ~ 3cm, use road roller to carry out several by designing requirement immediately and roll, the planarization on guarantee road surface and compactness;
5, use the super sticky wearing layer paver vehicle a layer thickness that paves to be the super sticky wearing layer 4 of about 0.8 ~ 1.0cm, and roll accordingly;
6, open to traffic.
For a person skilled in the art, according to above technical scheme and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
