Description
[technical field]
The present invention relates to a kind of emulsified asphalt slurry seal, especially a kind of mixed the technology that polymer fiber strengthens emulsified asphalt slurry seal.
[background technology]
Flexible pavement because be in wind throughout the year, drench with rain, the erosion of natural climates such as Exposure to Sunlight, freeze thawing, make pitch and mineral aggregate in the ground surface material constantly produce the variation of physics and chemistry, and reduce the ability of its acclimatization variation gradually.Again owing to exercise the effect of vehicle on the road surface, can cause flexible pavement constantly to ftracture, and along with the appearance in crack, can cause the permeable of road surface, also will cause the deliquescing of basic unit and the appearance of surface imperfection groove, thereby the road surface is degenerated, will reduce the running velocity of vehicle like this, increase the wearing and tearing and the oil consumption of vehicle.Therefore, flexible pavement is carried out the important step that preventive maintenance is protection flexible pavement, prolongation road life, raising conevying efficiency, reduction cost of transportation as early as possible.
Emulsified asphalt slurry seal is a kind of road surface preventive maintenance technology that develops rapidly in recent years, is to make aggregate with the grating aggregate chips or the sand of particulate formula, is binding material with the mulseal, paves into pitch table place thin layer behind the filled cold mixing.Emulsified asphalt slurry seal has that speed of application is fast, compactness is high, adhesion is strong, uses manpower and material resources sparingly, pollution-free, prolong construction seasons, advantage such as good in economic efficiency, but increase along with making emulsified asphalt slurry seal practice in recent years, recognize that emulsified asphalt slurry seal relies on pitch as binder merely, the making aftershaping time is long, early strength is low, close traffic maintenance difficulty, high temperature season is easily softening, the opposing permanent deformation is low, poor durability can not satisfy big traffic, heavy traffic and the big demand of common road flexible pavement distortion.
In order further to improve the emulsified asphalt slurry seal pavement performance, make emulsified asphalt slurry seal can be applied to the high-grade highway of big traffic, heavy traffic, by using technology such as modified bitumen emulsifier, interpolation new material, impel the emulsified asphalt slurry seal technology to be widely used in recent years.
[summary of the invention]
The purpose of this invention is to provide that a kind of moulding is fast, intensity is high, be easy to maintenance, high temperature season be difficult for softening, can resist permanent deformation, can satisfy big traffic, the emulsified asphalt slurry seal technology of heavy traffic and common road flexible pavement demand.
A kind of profiled-cross-section hollow polymer fiber strengthens emulsified asphalt slurry seal, it is fibrous by the emulsified asphalt slurry seal of routine and profiled-cross-section single hole or porous polymer, wherein, the content of profiled-cross-section single hole or porous polymeric fibres is 0.1～1.0% of bitumen slurries compound gross weight.
Polymer fiber can be polyester fiber, polyacrylonitrile fibre, Fypro, or by these fibrous assorted fibres.
" profiled-cross-section " of polymer fiber is meant that the cross section of fiber is any regular or irregular geometry, for example cross, trilobal, groined type, star, quincunx etc." hollow " is meant that this fiber is not solid, but the structure in one or more holes is arranged vertically.
The profiled-cross-section hollow polymer fiber strengthens the preparation method of emulsified asphalt slurry seal compound: will prepare earlier conventional emulsified asphalt slurry seal required gather materials and fiber evenly mixes and stirs, and then adding mulseal, water, filler and additive, stir mixing and stirring in the storehouse of slurry seal mixer, promptly obtain the compound that odd-shaped cross section hollow polymer fiber of the present invention strengthens emulsified asphalt slurry seal.
The invention has the beneficial effects as follows: 1) profiled-cross-section hollow polymer fiber adsorptive pitch in a large number, improve the affinity and the even Combination of fiber and bituminous concrete, make profiled-cross-section hollow polymer fiber of the present invention strengthen emulsified asphalt slurry seal and have the anti-rut of high temperature, low temperature freedom from cracking preferably, and excellent waterproof, anti-water damage property; 2) the profiled-cross-section hollow polymer fiber can absorb the stress that produces because of contraction in warm compression process, prevent the generation and the development in crack, make profiled-cross-section hollow polymer fiber of the present invention strengthen emulsified asphalt slurry seal and have good antiskid, wear-resisting, shock resistance, cracking resistance and resistance to freezing and thawing; 3) implementation method is simple, can utilize original preparation equipment directly to prepare, and needn't invest new equipment; 4) profiled-cross-section hollow polymer fiber enhancing emulsified asphalt slurry seal of the present invention can be applicable to various standard highways.
[specific embodiment]
Preparing the equipment that profiled-cross-section hollow polymer fiber of the present invention strengthens emulsified asphalt slurry seal, can be common slurry seal equipment.
Beneficial effect of the present invention depends primarily on the good oil absorbency that the profiled-cross-section hollow polymer fiber is had.Following table is that the performance of profiled-cross-section porous polyester fiber and other several fibers compares:
The performance of several fibers relatively
As can be seen from the table, the more common polyester fiber of oil absorbency of single hole polyester fiber and profiled-cross-section porous polyester fiber is significantly increased.
