Abstract
The utility model discloses a super-sticky seal coat for an asphalt pavement. The super-sticky seal coat comprises a super-sticky cold-mixing material wearing layer arranged on the original pavement, wherein a high-performance modified emulsified asphalt bonding layer is arranged between the pavement and the super-sticky cold-mixing material wearing layer. When the super-sticky seal coat for the asphalt pavement is used, the high-performance modified emulsified asphalt bonding layer and the super-sticky cold-mixing material wearing layer are simultaneously paved on the original pavement. The super-sticky seal coat for the asphalt pavement has the characteristics of super sticking, high water prevention, high skidding resistance, crack resistance, low carbon, energy saving and environmental friendliness.
Description
Technical field
The utility model belongs to the asphalt pavement conserving technical field, is specifically related to the ultra seal layer of a kind of flexible pavement.
Background technology
Bituminous pavement preventive maintenance technology kind is more, to pavement disease type difference different maintenance processes and technology is arranged.Wherein little table place technology had obtained using widely as a kind of preventive maintenance technology that improves former pavement skid resistance ability, anti-water damage ability, prolongation pavement life, the appearance of a street attractive in appearance in recent years.Little table place technology is the modified emulsifying asphalt slurry mixture that on original road surface, directly paves, and what cementitious matter adopted is the SBR modified emulsifying asphalt.The defective of little table place technology is relatively poor with former road surface bond effect, is prone to come off, and the difference noise is big, and the function of surface decay is fast, and cracking resistance does not use birthday noodle shorter.In addition; Though ultra-thin wearing layer technology of the prior art can overcome the part defective of little table place technology; But because its wearing layer employing is hot-mix asphalt mixture, the structure bed thickness is so the carbon emission amount is big, cost is high; And needing the large-scale hot-mix asphalt mixture mix equipment of configuration to construct, economic benefit and social benefit are all undesirable.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the order of the utility model is to provide a kind of flexible pavement ultra seal layer, has the characteristics of ultra bonding, high waterproof, high antiskid, low noise, cracking resistance, low-carbon (LC), energy-conserving and environment-protective.
To achieve these goals; The technical scheme that the utility model adopts is: the ultra sticking abrasion seal of a kind of flexible pavement; Include the road surface, on the road surface, be provided with ultra sticking cold mixing material wearing layer, between road surface and ultra sticking cold mixing material wearing layer, be provided with high-performance modified mulseal tack coat.The road surface is connected with high-performance modified mulseal tack coat.
Said ultra sticking cold mixing material wearing layer comprise by gather materials, cement, water, composite modified emulsification asphalt, fiber and liquid additive cold mixing form, its proportion of composing is for gathering materials: cement: water: composite modified emulsification asphalt: fiber: liquid additive=100:0～3:4～8:8～15:0～0.50:0～1.
The thickness of said ultra sticking cold mixing material wearing layer is 10mm～20mm;
Said gathering materials is that rubble, particle diameter are 0.075mm～12mm.
Said composite modified emulsification asphalt is SBS and SBR composite modified emulsification asphalt, and is cationic, and its solid content is 60%～70%.
Said fiber is a glass fiber, and specification is 2000 g/km～3000 g/km, length 8mm～20mm.
The material of said high-performance modified mulseal tack coat is the SBS modified emulsifying asphalt, and its solid content is 55%～70%, and spilling the cloth amount is 0.2 kg/m
2～0.25kg/m
2
The utlity model has following advantage:
1) adopts SBS and SBR composite modified emulsification asphalt cementitious materials, have plurality of advantages such as high-temperature stability high and low temperature crack resistance is good, water stability height, than SBR modified emulsifying asphalt high-temperature behavior, good endurance as ultra sticking cold mixing material wearing layer; Aggregate grading adopts gap grading, and excellent in addition cementitious matter performance has reduced road surface driving noise greatly.
2) add fiber in the ultra sticking cold mixing material, improved whole adhesion strength, shear strength and the anti-fatigue performance of compound, better than micro-surfacing mixture performance.
3) adopt high-performance modified mulseal as tack coat; Crack and the part loose structure little to former road surface have repair function; Improve the adhesion strength and the water resistance of wearing layer and original flexible pavement greatly, reduced and come off, improved crack resistance; Slow down the rate of decay of function of surface, prolonged service life of road surface.
4) the wearing layer compound adopts the cold mixing technology, and cementitious materials is mulseal in addition, all need not at high temperature to spray and mix, reduces more than 90% with ultra-thin wearing layer compared with techniques carbon emission ratio, and comprehensive energy consumption reduces more than 80%, and effects of energy conservation and environmental protection is obvious.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the structural principle and the operating principle of utility model are done further explain.
With reference to Fig. 1, the ultra sticking abrasion seal of a kind of flexible pavement includes road surface 1, on road surface 1, is provided with ultra sticking cold mixing material wearing layer 3, between road surface 1 and ultra sticking cold mixing material wearing layer 3, is provided with high-performance modified mulseal tack coat 2.
Said ultra sticking cold mixing material wearing layer 3 be by gather materials, cement, water, composite modified emulsification asphalt, fiber and liquid additive cold mixing obtain the moulding that paves of ultra sticking cold mixing material, its proportion of composing is for gathering materials: cement: water: composite modified emulsification asphalt: fiber: liquid additive=100:0～3:4～8:8～15:0～0.5:0～1.
The thickness of said ultra sticking cold mixing material wearing layer is 10mm～20mm;
Said gathering materials is that rubble, particle diameter are 0.075mm～12mm.
Said composite modified emulsification asphalt is SBS and SBR composite modified emulsification asphalt, and is cationic, and its solid content is 60%～70%.
Said fiber is a glass fiber, and specification is 2000 g/km～3000 g/km, length 8mm～20mm.
The material of said high-performance modified mulseal tack coat is the SBS modified emulsifying asphalt, and its solid content is 55%～70%, and spilling the cloth amount is 0.2 kg/m
2～0.25kg/m
2
The operating principle of the utility model is:
High-performance modified mulseal tack coat 2 and ultra sticking cold mixing material wearing layer 3 simultaneously pave on protobitumen road surface 1; High-performance modified mulseal tack coat has been repaired part crack, former road surface and former road surface and ultra sticking cold mixing material wearing layer secure bond has been in the same place; Form whole; Improve high temperature performance, water stability and the anti-fatigue performance of flexible pavement, prolonged pavement life.
