Abstract
The invention discloses a kind of town roads to cross bituminous grout concrete pavement construction engineering method, is made of base course, sand stone layer, water layer, Bituminous Concrete Permeable Pavement layer and phase-change microcapsule excessively, construction procedure is as follows: a, the impurity for clearing up roadbed layer surface；B, it is laid with sand stone layer after the completion of base course is cleared up and is compacted；C, water layer was laid in sand stone layer；D, pitch and concrete are subjected to mixing proportion, obtain the mixture with certain coefficient of permeability, then phase-change microcapsule is incorporated into bituminous concrete mixture, and carries out mixing；E, the resulting mixed material of step d was laid on water layer, and obtained Bituminous Concrete Permeable Pavement layer；F, sprinkling maintenance.Advantage is: water penetration of the present invention is preferable and can alleviate bituminous pavement high temperature.
Description
Technical field
The invention belongs to town road technical fields, cross bituminous grout concrete road surface more particularly, to a kind of town road and apply
Work engineering method.
Background technique
Currently, asphalt concrete pavement has been widely used on each provincial, and municipal level road with the development of the city,
Mainly have the characteristics that allow evenness of road surface to lack dirt, durable；Its water penetration of existing asphalt concrete pavement is poor, in this way
So that road often generates serious waterlogging in rainy season, Public Traveling safety and efficiency are influenced；In addition, since asphalt material is to the sun
The absorption of energy, bituminous pavement surface temperature can be higher in summer, this makes the high-temperature stability of bituminous pavement by tight
High test seriously affects the service performance and traffic safety of bituminous pavement.
Summary of the invention
The purpose of the present invention is in view of the deficiency of the prior art, provide a kind of town road to cross bituminous grout coagulation
Soil surface construction, it has the characteristics that water penetration is preferable and can alleviate bituminous pavement high temperature.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of town road crosses bituminous grout concrete
Pavement construction engineering method is made of base course, sand stone layer, water layer, Bituminous Concrete Permeable Pavement layer and phase-change microcapsule excessively, applies
Steps are as follows for work:
A, the impurity of roadbed layer surface is cleared up；
B, it is laid with sand stone layer after the completion of base course is cleared up, sand stone layer is collectively formed by rubble or gravel, and uses road roller
Compacting；
C, it was laid with water layer in sand stone layer, crosses water layer and is made of natural coarse sand or fine aggregate, to material before laying
Material is matched, and the coefficient of permeability of 1.5~2mm/s is reached；
D, pitch and concrete are subjected to mixing proportion, the mixture with certain coefficient of permeability are obtained, then by phase transformation
Microcapsules are incorporated into bituminous concrete mixture, and carry out mixing；
E, the resulting mixed material of step d was laid on water layer, and obtained Bituminous Concrete Permeable Pavement layer；
F, sprinkling maintenance.
The phase-change microcapsule is paraffin microcapsule.
The outer diameter crossed water space and be less than phase-change microcapsule crossed on water layer.
It can effectively be restored the invention has the advantages that compared with the prior art: the present invention, recharge of groundwater, dimension
Belowground ecosystem balance is held, prevents urban waterlogging and road surface from collapsing；The suction that phase-change microcapsule can be converted by solid-liquid phase change
Heat-exothermic process adjusts the temperature on road surface, mitigates the temperature on hot weather road surface, improves the service performance on road surface and promoted and handed over
Logical safety.
Specific embodiment
As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.
Embodiment: a kind of town road crosses bituminous grout concrete pavement construction engineering method, by base course, sand stone layer, crosses water
Layer, Bituminous Concrete Permeable Pavement layer and phase-change microcapsule composition, construction procedure are as follows:
A, the impurity of cleaning roadbed layer surface, the section basal plane that base course is generally old pavement to be rebuilt or newly opens up,
It generally all has more impurity particle, these sundries impact construction in order to prevent, are generally all carried out clearly with tool
Reason, base course generally tamp plain soil layer, and with preferable water penetration, the rainwater for collecting in this layer can be fed directly to underground
Water layer.
B, it is laid with sand stone layer after the completion of base course is cleared up, sand stone layer is collectively formed by rubble or gravel, and uses road roller
Compacting；Sand stone layer also has more lower water space after compaction, flows down convenient for rainwater due to being made up of rubble or gravel
To base course.
C, it was laid with water layer in sand stone layer, crosses water layer and is made of natural coarse sand or fine aggregate, to material before laying
Material is matched, and the coefficient of permeability of 1.5~2mm/s is reached.
D, pitch and concrete are subjected to mixing proportion, the mixture with certain coefficient of permeability are obtained, then by phase transformation
Microcapsules are incorporated into bituminous concrete mixture, and carry out mixing；Phase-change microcapsule is paraffin microcapsule, can be passed through
Heat absorption-exothermic process of solid-liquid phase change conversion adjusts the temperature on road surface, mitigates the temperature on hot weather road surface, improves road surface
Service performance and promoted traffic safety；The outer diameter of phase-change microcapsule, which was greater than in water layer, crosses water space, can place in this way
Mutually become microcapsule permeable to arrive in water layer.
E, the resulting mixed material of step d was laid on water layer, and obtained Bituminous Concrete Permeable Pavement layer.
F, sprinkling maintenance.
Claims (3)
