Description
Technical field
Pavement structure and construction technology are the utility model is related to, specially a kind of ultra-thin bituminous skidding resistant surface road surface of durability
Structure.
Background technology
In recent years, sharply increasing due to overload, heavy-duty vehicle and the magnitude of traffic flow, though most of highways that early stage builds
Right pavement structure is complete, but the performance such as skid resistance of pavement, flatness, comfortableness has substantially reduced, and some can not even expire
Sufficient requirement, there is larger potential safety hazard.
Therefore, its function of surface is recovered using the technology for overlaying one layer of Asphalt Concrete Overlay.
As the important component of Asphalt Concrete Overlay maintenance technology, the effect of interlaminar bonding material is protobitumen
Together with mixture pavement surface layer is securely bonded to Asphalt Concrete Overlay, it is allowed under Vehicle Load between each surface layer
Mutual breaks down will not occur, and vehicular load can be delivered to next surface layer.
One of an important factor for quality of binding material bond effect is influence service life of road surface, and bituminous concrete
One of key of cover success or failure.
But existing Asphalt Concrete Overlay maintenance technology is present that paving thickness is big, poor durability, service life is shorter,
Drainage and antiskid poor performance, interlaminar bonding scarce capacity, easily produce cutting slippage and destroy, vehicle traveling noise is larger.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model be propose it is a kind of have be compacted into
The durability that type thickness of thin, drainage are good, skid resistance is good, planarization is good, good endurance, cost economy, traffic noise are low is ultra-thin
Bituminous skidding resistant surface pavement structure.
The ultra-thin bituminous skidding resistant surface pavement structure of durability of above-mentioned technical problem is can solve the problem that, its technical scheme includes mixed
Solidifying soil surface basic unit or Asphalt Pavement Base, except that also including being coated on concrete road surface basic unit or Asphalt Pavement Base
The ultra-thin pitch of the upper not viscous wheel interlayer adhesion coating for being used to prevent cutting slippage from destroying and compacting on not viscous wheel interlayer adhesion coating resists
Sliding top layer, the compacted depth of the ultra-thin bituminous skidding resistant surface is 15mm~25mm.
The ultra-thin bituminous skidding resistant surface is preferably suppressed using open gradation hot-mix asphalt mixture, ultra-thin bituminous skidding resistant surface
The maximum particle diameter gathered materials is not less than 6% no more than 9.5mm, bitumen aggregate ratio.
The not viscous wheel interlayer adhesion coating is preferably coated with using hot melt modified pitch, the coating dosage of not viscous wheel interlayer adhesion coating
Using 0.1kg/m2~1kg/m2, wheel firm time is not glued and is limited to less than 3 minutes, you can cannot not reach viscously subsequent construction vehicle wheel
The effect of tire.
The beneficial effects of the utility model：
1st, antiskid performance of the present utility model is good.
2nd, excellent in durability of the present utility model.
3rd, evenness of road surface of the present utility model is good.
4th, the utility model can effectively reduce traffic noise.
5th, compaction moulding thickness of thin of the present utility model, material can be saved compared to traditional wearing course, had preferably economical
Property.

Hot melt modified pitch, the coating dosage of the hot melt modified pitch use 0.1kg/m2~1kg/m2, not viscous wheel firm time
Less than 3 minutes, as shown in Figure 1.
The ultra-thin bituminous skidding resistant surface 3 is using open gradation hot-mix asphalt mixture spreading on not viscous wheel interlayer adhesion coating 2
And compaction moulding is 15mm~25mm thickness, the maximum particle diameter that ultra-thin bituminous skidding resistant surface 3 gathers materials is no more than 9.5mm, oilstone
Than not less than 6%, as shown in Figure 1.
The construction procedure of the ultra-thin bituminous skidding resistant surface pavement structure of the utility model durability is：
1st, survey the damage status of concrete road surface basic unit 1 or Asphalt Pavement Base and carry out pavement patching, after repairing
Road surface clean up and remove foreign matter.
2nd, heat molten type modified pitch is coated with the concrete road surface basic unit 1 or Asphalt Pavement Base repaired and cleared up and is waited
Wheel interlayer adhesion coating 2 cannot not be made viscously after hardening in no more than 3 minutes, the coating dosage of the hot melt modified pitch is 0.1kg/m2
~1kg/m2。
3rd, it is ultra-thin pitch antiskid to let grading hot-mix asphalt mixture and compaction moulding go in the not viscous upper berth of wheel interlayer adhesion coating 2
