Description
Technical field
The present invention relates to technical field of road construction, specially a kind of road construction method.
Background technique
Road construction frequently with ground surface material be cement, sandy soil etc. and water mixture, be 5 DEG C below low in temperature
Generally stop ground surface material construction under the conditions of temperature, because the water in ground surface material and sandy soil material are easy condensation in this case,
Although increasing the compression strength and stretch capability of ground surface material to a certain extent, once temperature recovery, therein
Condensation is dissipated, so that the intensity of ground surface material is substantially reduced.
With the development of economy, construction project rapidly increases, but the various severe geological conditions in process of construction
It not can avoid, urban operating mechanism or road are built on soft soil foundation, soft base is not punished or dealt with improperly, frequently can lead to
Basic unstability or Excessive Settlement cause building facility to destroy or be unable to normal use.
Existing asphalt road or bituminous concrete road are handing over fork in the road etc. more crowded through use after a period of time
Section, temperature is excessively high so that pitch softens, and in long-time excess load in use, especially in the case where weak subgrade, is easy
Pavement crack is caused, accelerates the damage on road surface, influences road life, so it is above-mentioned to solve to propose a kind of road construction method
The problem of proposed.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of road construction method, have the advantages that long service life,
Existing asphalt road or bituminous concrete road are solved through use after a period of time, in friendship fork in the road etc. than more crowded
Section, temperature is excessively high so that pitch softens, and in long-time excess load in use, especially in the case where weak subgrade, is easy to make
At pavement crack, the problem of accelerating the damage on road surface, influence road life.
(2) technical solution
To realize that above-mentioned long service life purpose, the present invention provide the following technical solutions：A kind of road construction method, including

(6) it road test and records.
Preferably, in the step (1), preparation includes mix asphalt concrete, thickness collection used in bituminous concrete
Material, filler and pitch, kerbstone, Lu Gou, inspection shaft and other structures object contact surface on should be uniformly coated with a thin layer drip
Blueness will check two sides kerbstone fine status, and position elevation, which is not inconsistent requirement, to be corrected, and must replace in time if any disturbance or damage,
Especially it is noted that situation is tamped at the back side, guarantees in decking and rolling, be not extruded, move, and while forming roadbed, if
Gutter is set.
Preferably, in the step (2), when being laid with bed course, bed course use thin sand, thin sand by 51% it is broken
Stone, 25% clinker, 24% rendzinas are constituted, and the particle size of rubble is the rubble of 2-10mm, and the partial size of clinker is 3-
6mm, the thickness of bed course is not less than 5cm, and is compacted using road roller, need to also be on road shoulder and road surface after being compacted road surface
Sealing material is filled at gap and at construction joint, the height of sealing material is lower than the height on road surface, and sealing material has and gap
The property that side is securely connected.
Preferably, in the step (3), when the hot-mix asphalt mixture mixed is without making immediately, heat preservation can be put into
The storage of finished product storage bin, storage time must not exceed 72h, and when storage bin is without heat-preserving equipment, the storing time of permission should be to meet
Subject to paving material requires, the transport of green mixture is transported using dumper, when from mixing equipment to dumper blowing, for reduction
The segregation phenomenon that thickness is gathered materials often unloads a pipeful of mixture and moves automobile position, when haul, the covering of self-unloading vehicle tarpaulin.
Preferably, in the step (4), on bed course be laid with one layer of rubber asphalt, will be laid with rubber asphalt after described in
Bed course be compacted using road roller, it is 2Kg/m that the laying amount of rubber asphalt, which is no less than, is uniformly spread on the pitch of compacting
If the emulsified asphalt of one layer of melting, when paving, asphalt must slowly, pave uniformly and uninterruptedly, must not be with
Meaning conversion rate stops over, and the height of the mixture in paver screw feed appliance keeps being not less than the three of feed appliance height
/ bis-, and guarantee not isolate on paver full duration section.
Preferably, in the step (5), the transverse joint between upper layer and lower layer should be staggered 60cm or more, and in machinery
The place that cannot be paved and rebuild can use Manual and trimming after obtaining supervising engineer and agreeing to, and complete cleaning work.
Preferably, in the step (6) in the paving process of test section, analysis is conscientiously made a record, is actively received
The construction quality of supervising engineer or the supervision of engineering quality supervision department, checkout facility section, determines related achievement, making terminates
Afterwards, just every content of the test proposes test summary report in time, reports supervising engineer to examine, as manufacture bases.
(3) beneficial effect
Compared with prior art, the present invention provides a kind of road construction methods, have following beneficial effect：
Roof insulating heating and thermal insulation, ground surface material stirring and construction are installed in the section for needing to construct by the road construction method
It is carried out all in roof insulating, guarantee rolls temperature, the porosity and infiltration coefficient of ground surface material is reduced, to mitigate ground surface material
Compacting difficulty, be laid on road after construction with plastic foil, then cover insulating layer, road surface material dry not yet can be made
Material heat preservation improves intensity, while it also has resistance a possibility that ensureing Forming Quality, reduce the drying shrinkage and cracking of asphalt roads
Performance is fired, and effectively reduces the waste rate of material, has saved cost, is very suitable to road surface and the weak subgrade of high quality
Pavement usage can greatly improve the service life on road surface.
