Abstract
The utility model relates to a double -deck synchronous surface dressing stress absorption structure glues the oil reservoir and lays on the cement concrete board, glues the upper surface of oil reservoir and has laid first hot SBS modified asphalt layer, and first single seed footpath metalling has been laid to the upper surface on first hot SBS modified asphalt layer, and the hot SBS modified asphalt layer of second has been laid to the upper surface of first single seed footpath metalling, and second single seed footpath metalling has been laid to the upper surface on the hot SBS modified asphalt layer of second. This double -deck synchronous surface dressing stress absorption structure is through setting up double -deck synchronous surface dressing stress absorbing layer, and because of its high viscosity modified asphalt who has the high dose, double -deck rubble closely inlays crowdedly from top to bottom each other, and has some macrovoids between double -deck rubble, and when cement concrete board seam crossing took place the shrink with vertical deformation, this stress absorbing layer can eliminate the stress concentration of seam crossing effectively to production and the development eliminating or slow down reflective cracking.
Description
Technical field
The utility model belongs to technical field of building construction, particularly relates to a kind of double-deck synchronous surface dressing stress absorption structure.
Background technology
From last century early eighties, domesticly build a large amount of cement concrete pavement highways.At present, because transport development needs, a large amount of cement concrete pavement can not meet economic development to road passage capability and the higher requirement of ride quality demand, thus namely " morning-night " engineering is increasing to cause Cement Concrete Pavement bituminous concrete." morning-night " project durability and functional performance by reflection crack generation and influence on development significantly, but this problem is resolved so far not yet.This type of reflection crack is produced by the acting in conjunction of temperature and load, the vertical shearing stress produced under stretcher strain and load action because of the tensile stress under variations in temperature causes vertical deformation, produce stress at cement board seam crossing concentrate and to skin coat transmission, thus skin coat ruptured.Therefore, how science, the technology that reasonably prevents or slow down reflection crack to produce still need to improve.
Utility model content
The utility model provides the double-deck synchronous surface dressing stress absorption structure that a kind of structure is simple, easy to install, increase work efficiency for solving in highway technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution highway technology is:
This double-deck synchronous surface dressing stress absorption structure comprises: viscous oil layer, the first hot SBS modified asphalt layer, the first simple grain footpath macadam, the second hot SBS modified asphalt layer, the second simple grain footpath macadam;
Viscous oil layer is laid on cement concrete slab, the upper surface of viscous oil layer is equipped with the first hot SBS modified asphalt layer, the upper surface of the first hot SBS modified asphalt layer is equipped with the first simple grain footpath macadam, the upper surface of the first simple grain footpath macadam is equipped with the second hot SBS modified asphalt layer, and the upper surface of the second hot SBS modified asphalt layer is equipped with the second simple grain footpath macadam.
The utility model can also adopt following technical measures:
The diameter of the first described simple grain footpath macadam medium stone is 19-31.5mm.
The diameter of the second described simple grain footpath macadam medium stone is 13.2-19mm.
The advantage that the utility model has and good effect are: this double-deck synchronous surface dressing stress absorption structure is by arranging double-deck synchronous surface dressing stress absorbing layer, because it has the high-viscosity modified asphalt of high dose, double-deck rubble is mutual closely embedded squeezing up and down, and between double-deck rubble, there is some macrovoids, when cement concrete slab seam crossing shrinks with vertical deformation, the stress that this stress absorbing layer can eliminate seam crossing is effectively concentrated, thus eliminates or slow down the producing and developing of reflection crack.
Accompanying drawing explanation

In figure: 1, viscous oil layer; 2, the first hot SBS modified asphalt layer; 3, the first simple grain footpath macadam; 4, the second hot SBS modified asphalt layer; 5, the second simple grain footpath macadam.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to shown in Fig. 1: this double-deck synchronous surface dressing stress absorption structure comprises: viscous oil layer 1, first hot SBS modified asphalt layer 2, first simple grain footpath macadam 3, second hot SBS modified asphalt layer 4, second simple grain footpath macadam 5;
Viscous oil layer 1 is laid on cement concrete slab, the upper surface of viscous oil layer 1 is equipped with the first hot SBS modified asphalt layer 2, the upper surface of the first hot SBS modified asphalt layer 2 is equipped with the first simple grain footpath macadam 3, the upper surface that the upper surface of the first simple grain footpath macadam 3 is equipped with the hot SBS modified asphalt layer 4 of the second hot SBS modified asphalt layer 4, second is equipped with the second simple grain footpath macadam 5.
The diameter of the first described simple grain footpath macadam 3 medium stone is 19-31.5mm.
The diameter of the second described simple grain footpath macadam 5 medium stone is 13.2-19mm.
By slip casting, change first spread one deck sticking layer oil on cement concrete slab that plate etc. handles well, adopt the hot SBS modified asphalt layer 2 of synchronous macadam seal paver spread first, temperature is 160 ~ 175 DEG C, consumption is 2.0kg/m2, and synchronous evenly spreading stone sizes is the first simple grain footpath macadam 3 of 19-31.5mm, rubble completely paving rate is 70-80%, then carries out 4 times with light-duty pneumatic-tired rollers and roll, and rubble and pitch is bondd stable.
After first floor spreading is stable, and then adopt the hot SBS modified asphalt layer 4 of synchronous macadam seal paver spread second, temperature is 160 ~ 175 DEG C, and consumption is 1.0kg/m
2, and synchronous evenly spreading stone sizes is the second simple grain footpath macadam 5 of 13.2-19mm, and rubble completely paving rate is 70-80%, then carries out 4 times with light-duty pneumatic-tired rollers and roll, make levels rubble mutually closely embedded squeezing stablize.By arranging double-deck synchronous surface dressing stress absorbing layer, because it has the high-viscosity modified asphalt of high dose, double-deck rubble is mutual closely embedded squeezing up and down, and between double-deck rubble, there is some macrovoids, when cement concrete slab seam crossing shrinks with vertical deformation, the stress that this stress absorbing layer can eliminate seam crossing is effectively concentrated, thus eliminates or slow down the producing and developing of reflection crack.
The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
