Abstract
The invention discloses an ultra-thin asphalt sand seaming method, comprising the following steps of: spraying viscous oil asphalt at the part which is 2.5-3m from a seam in a molding area; paving a layer of geogrid which exceeds the seam about 0.5-1m on viscous oil; paving ultras-asphalt sand mixture on the geogrid; carrying out joint-cutting treatment after molding; spraying the viscous oil asphalt at the part which is 2.5-3m from the seam on the section on which the asphalt is not paved before preparation of construction of a new construction section; then adding a layer of geogrid, paving the asphalt sand mixture on the geogrid; and grinding and molding. The ultra-thin asphalt sand seaming method disclosed by the invention is simple and convenient, and strong in operability; compaction of the seam on the asphalt sand pavement is achieved; the problem that a crack easily generates is solved; the quality of the asphalt sand pavement is significantly improved.
Description
Technical field
The invention belongs to building engineering construction method, particularly a kind of ultrathin sand asphalt seaming method.
Background technology
Sand asphalt compound fully mixes mixing in this state by the sand material of various particle diameter and a certain proportion of pitch to form, the advantage such as the comfortable and noise of sand asphalt surface fine, attractive in appearance, good waterproof performance, driving is little, the asphalt sand pavement of making in good basic unit has good practicality; Shortage crushed stone material or rubble exploitation and cost of transportation expensive, but the abundant and exploitation of natural sand material, cost of transportation lower ground district, build the good approach that asphalt sand pavement is development flexible pavement; Than other hot asphalt mixture surface layers of making on the road of applicable making sand asphalt surface layer, can saving construction cost, reduce costs.
Asphalt sand pavement construction technology is substantially identical with the construction technology of domestic flexible pavement, during general domestic process flexible pavement seam, if when can not adopt hot seam, all add at the bitumen layer place that constructed baffled or cut neat, when the adjacent road section surface of making, be coated with at seam crossing and spill a small amount of adhesion coating pitch, overlap laying 5-10CM is answered when paving, with manually the compound shovel spreading face in first half that paves being walked after paving, first walk on compacting road surface when rolling, roll laying 10-15CM, then compacting newly spreads part, extend through compacting road surface 10-15CM again, fully by tight for seam compacting, general road roller vertically rolls seam crossing, but because sand asphalt grating particle is little, thickness is generally at 2-4CM, if shaping road surface is long for interval time with pavement construction of newly constructing, molded road surface rigidity is formed, and the asphalt sand pavement newly paved is because particle is little, thickness is very thin, adopts above-mentioned way to roll, very easily cause pushing phenomenon, cause asphalt sand pavement seam crossing to be repeatedly difficult to compacting, quality is not easy qualified, and the seam crossing after namely shaping very easily produces crack.
Summary of the invention
Technical problem to be solved by this invention proposes a kind of ultrathin sand asphalt seaming method, and convenient and simple, strong operability, realizes the compacting of asphalt sand pavement seam crossing, avoids the generation in crack, can significantly improve asphalt sand pavement quality.
For achieving the above object, a kind of ultrathin sand asphalt seaming method of the present invention, its technical scheme is as follows:
The first step: spray viscous oil pitch close to seam crossing 2.5 ~ 3 meters of in shaping area;
Second step: overlay the geo-grid of one deck slightly above seam crossing about 0.5 ~ 1 meter in viscous oil;
3rd step: pave ultra-albanite sand compound in geo-grid;
4th step: wait shaping after carry out joint-cutting process;
5th step: wait new construction paragraph to prepare construction front in the sand asphalt section that do not pave, viscous oil pitch is sprayed at distance seam crossing 2.5 ~ 3 meters of again, overlays one deck geo-grid more thereon, geo-grid is carried out stand sand asphalt compound;
6th step: oppositely roll, namely never shaping area starts to roll to shaping area, and road roller speeds control, at 0.5 meter per second, carries out roller-compaction.
The ultrathin sand asphalt seaming method of described one, when carrying out roller-compaction, road roller becomes miter angle with seam crossing, not easily produces passing.
The ultrathin sand asphalt seaming method of one of the present invention, convenient and simple, strong operability, achieves the compacting of asphalt sand pavement seam crossing, solves the problem very easily producing crack, significantly improve asphalt sand pavement quality.
Accompanying drawing explanation
Fig. 1 is constructing structure schematic diagram of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of ultrathin sand asphalt seaming method, its technical scheme is as follows:
The first step: spray viscous oil pitch close to seam crossing 2.5 ~ 3 meters of in shaping area 1;
Second step: overlay the geo-grid of one deck slightly above seam crossing 4 about 0.5 ~ 1 meter in viscous oil;
3rd step: pave ultra-albanite sand compound in geo-grid;
4th step: wait shaping after carry out joint-cutting process;
5th step: wait new construction paragraph to prepare construction front in the sand asphalt section that do not pave, viscous oil pitch is sprayed at distance seam crossing 2.5 ~ 3 meters of again, overlays one deck geo-grid more thereon, geo-grid is carried out stand sand asphalt compound;
6th step: oppositely roll, namely never shaping area 2 starts to roll to shaping area, and road roller 3 speeds control, at 0.5 meter per second, carries out roller-compaction.
The ultrathin sand asphalt seaming method of described one, when carrying out roller-compaction, road roller becomes miter angle with seam crossing, not easily produces passing.
The ultrathin sand asphalt seaming method of one of the present invention, convenient and simple, strong operability, achieves the compacting of asphalt sand pavement seam crossing, solves the problem very easily producing crack, significantly improve asphalt sand pavement quality.
