Description

Town road drains temperature adjustment pavement construction engineering method
Technical field
The invention belongs to municipal road construction technical fields, drain temperature adjustment pavement construction more particularly, to a kind of town road Engineering method.
Background technique
Currently, people's trip quality requirement constantly upgrades, and transport development is also cured with the fast development of economic society Add the theory for highlighting " environmental-friendly ".In field of road, the use function on road surface how is improved, how to be provided to society high Safe, more comfortable, more environmentally friendly road surface properties, it has also become the fresh target that traffic department of China is pursued under the new period.It is existing Asphalt roads summer its surface temperature often as high as 60 DEG C or more, under extreme weather be even up to 80 DEG C or more, Pitch is seriously affected so that the high-temperature stability of bituminous pavement meets a severe test more than the softening point temperature of road asphalt The service performance and traffic safety on road surface;And in heavy rain season, bituminous pavement meets with rain damage, since drainage performance is bad, It is often possible to cause accumulation of rainwater, largely effects on the passage of road.
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 draining temperature adjustment road surface Construction, it has the characteristics that pavement temperature and fast and effectively venting ponding can be automatically adjusted.
To achieve the goals above, the technical scheme adopted by the invention is that: apply on a kind of town road draining temperature adjustment road surface Work engineering method, it is characterised in that: including base road surface, the base road surface is from top to bottom by pitch temperature-control coating, asphalt tack coat, mixed Solidifying soil layer and cement stabilized macadam layer composition, processing step are as follows:
A, road surface to be onstructed is cleared up;
B, cement, rubble and water are subjected to mixing mixing by match ratio, shape on road surface to be onstructed is laid on after mixing At cement stabilized macadam layer;
C, cement stabilized macadam layer is compacted, and configures concrete according to the ratio, be laid on water at by concrete after configuring Concrete layer is formed on mud metalling;
D, it is laid with modified emulsifying asphalt on concrete layer, forms it into asphalt tack coat;
E, paraffin particles are mixed in asphalt material, temperature adjustment mixture is obtained by mixing, temperature adjustment mixture is laid on Pitch temperature-control coating is formed it on asphalt tack coat and with road roller compacting;
F, gutter is excavated in road surface two sides, the direction in gutter is parallel with road surface direction;
G, drain cover is disposed on gutter, drain cover upper level is lower than the height of pitch temperature-control coating.
The invention has the advantages that compared with the prior art: the present invention carries out solid-liquid by built-in paraffin particles Phase transformation, which is converted, adjusts the temperature on road surface, mitigates the temperature on hot weather road surface, improves the service performance on road surface and promotes traffic Safety;The gutter of both sides of the road setting can fast and effectively on venting road ponding, prevent excessive rainfall from gathering.
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 drains temperature adjustment pavement construction engineering method comprising base road surface, the base road surface from It is made of under pitch temperature-control coating, asphalt tack coat, concrete layer and cement stabilized macadam layer, processing step is as follows:
A, road surface to be onstructed is cleared up;Before construction, there are some impurity particles, house refuse and it can dash forward on base road surface These impurity are cleaned and are flattened by towering point block.
B, cement, rubble and water are subjected to mixing mixing by match ratio, are surely matched with specific mass according to 5% water, after mixing It is laid on formation cement stabilized macadam layer on road surface to be onstructed;The thickness of cement stabilized macadam layer is generally 150mm, and the partial size of rubble Generally between 10mm~20mm.
C, vibrating compacting is carried out to cement stabilized macadam layer by oscillating column pump, and configures concrete according to the ratio, will mixed after configuring Solidifying soil is laid on cement stabilized macadam layer and forms concrete layer, should the leveling of the side Bian Pu when being laid with concrete layer.
D, it is laid with modified emulsifying asphalt on concrete layer, forms it into asphalt tack coat, the laying of asphalt tack coat is adopted With the mode of sprinkling, when sprinkling, should uniformly spray, and at least repeat 2 to 3 times, and the thickness of sprinkling should control on the left side 0.5mm It is right.
E, paraffin particles are mixed in asphalt material, temperature adjustment mixture is obtained by mixing, temperature adjustment mixture is laid on Pitch temperature-control coating is formed it on asphalt tack coat and with road roller compacting, paraffin particles can absorb temperature at high temperature and change For liquid, the temperature of bituminous pavement is reduced with this, and it then passes through heat release and is returned to solid-state when temperature is restored to room temperature, this Sample can mitigate the surface temperature of hot weather bituminous pavement significantly.
F, gutter is excavated in road surface two sides, the direction in gutter is parallel with road surface direction, and the depth in gutter can root It is adjusted according to surface conditions, it is internal that there is drainage pipeline.
G, drain cover is disposed on gutter, drain cover upper level is lower than the height of pitch temperature-control coating;Draining Operculum colpi should be spaced setting, and compartment is away from generally 5m or so, and in this way by the guidance of drain cover, rainwater can be discharged into draining On drainage pipeline in ditch and water conservancy diversion is carried out, to prevent it from excessively gathering.
