Description
Technical field
The invention belongs to pavement recycling technical field, more particularly to a kind of cement concrete pavement regeneration repairing side
Method.
Background technology
Conventional cement concrete road surface crushes serious plate, is typically handled by the way of plate is renewed, that is, cuts original
Come after the concrete on road surface, the concrete paved with raw sheet same thickness.By changing the cement pavement of plate processing, substrate is excavated
Discontinuity at processing influence and new-old concrete pavement joint, can typically be destroyed again using 2~3 years rear boards.And
And, necessary close traffic in plate processing procedure is changed, curing cycle is longer, has influence on road surface running vehicle safety；Cost is higher, every square
250 yuan or so of rice；And old pavement material is mostly discarded, waste serious, do not meet national " building waste MAT'L recycling "
Proposal.
Cement concrete pavement regeneration, exactly makes full use of Deteriorated concrete pavement surface layer as main surface material,
Part new fine aggregate (medium coarse sand), water are suitably added, completes crush, mix and stir, paving and compaction moulding at the construction field (site), again shape
Into a kind of new maintenance technology with certain bearing capacity structure sheaf.This method is by making full use of Deteriorated concrete pavement surface layer
Material, selects appropriate mixture proportion with fine aggregate, can obtain the pretty good regeneration blended stock of quality.Changed with cement pavement
Plate is compared, and regeneration maintenance technology can obtain considerable economic benefit and notable with saving construction cost 40% or so
Social benefit.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of cement concrete pavement regeneration method for repairing and mending, the method is filled
Divide and utilize Old cement concrete waste and scrap, and pavement structure construction is convenient, the maintenance close traffic time is short.
In order to solve the above technical problems, the present invention uses following technical scheme：Cement concrete pavement regeneration is repaired
Method, by pavement structure from bottom to top include carry out successively roadbed treatment, sand bedding course construction, stabilization gravel subbase construction,
Graded broken stone base is constructed and bitumen macadam seal coat construction, bitumen macadam seal coat using the construction of two layers method, graded broken stone base and
Stabilization gravel underlayment is made using broken cement panel material.
Above-mentioned cement concrete pavement regeneration method for repairing and mending, comprises the following steps：
<1>Preparation of construction,<2>Roadbed treatment,<3>Sand bedding course construction,<4>Stabilization gravel subbase construction,<5>Level is with broken
Stone base layer construction,<6>Roller-compaction,<7>Health,<8>Bitumen macadam seal coat is constructed.
Step<1>Carried out by following operation：The serious plate of selection pavement breaking is crushed, and old concrete plate is broken into
Old concrete block within 30cm is standby.
Step<2>Carried out by following operation：Soft foundation change to fill out or ted Subgrade Compaction after processing, processing
95% should be not less than.
Step<3>Carried out by following operation：Uniform on the ground handled well to dispense the thick sand bedding courses of 1cm, sand bedding course should be selected
With the river sand that specification is middle sand.
Step<4>Carried out by following operation：15~25cm stone is selected uniformly to be placed on basal surface, it is big face-down, it is small
Up, firm stable between stone, dispenses thickness about 2cm river sands and fills up stone gap.
Step<5>Carried out by following operation：More than 20cm cement block machines are rolled into nominal maximum aggregate size 5cm rubble, with
River sand is more uniform than mix according to 7: 3 quality in thick, paves on granular sub-base face, and graded broken stone base thickness is 5~
10cm。
Step<6>Carried out by following operation：Road roller watering rolls the open to traffic after stable.
Step<7>Carried out by following operation：Water drenching daily 3 to 5 times, treats open to traffic stable shaping in 3~5 days.
Step<8>Carried out by following operation：Surface is cleaned, exposes stone, tar seal is carried out, is applied using two layers of layer spread method
Work, every layer of equivalent heated bitumen about 4~5kg/m2, crushed stone spreading amount is 70% or so of full paving product, per 2~3cm of thickness degree.
Maintenance, which is repaired, for existing road surface produces the problem of Old cement concrete waste and scrap wastes serious, inventor
A kind of cement concrete pavement regeneration method for repairing and mending is established, includes the roadbed carried out successively from bottom to top by pavement structure
Processing, sand bedding course construction, the construction of stabilization gravel subbase construction, graded broken stone base and bitumen macadam seal coat construction, pitch are broken
Stone sealing is made using two layers of method construction, graded broken stone base and stabilization gravel underlayment using broken cement panel material.Will
Invention is applied to Road network analysis, can make full use of Old cement concrete waste and scrap (regeneration rate reaches 70%), have
Effect solves the problem of building waste reclaims difficult；The convenient, the reliable in quality moreover, method is constructed, is obtained with certain bearing capacity
Pavement structure, can meet driving and require, greatly improve service life of road surface completely；Meanwhile, the construction and maintenance close traffic time
It is short, it is possible to reduce traffic accident occurrence frequency.In a word, the invention provides a kind of road construction green construction technology, water is met
Cement concrete maintenance of surface technical requirements and country widely popularize the objective of " resources conservation, building waste are recycled ", fit
Cement concrete pavement for grade to be relatively low, in the less demanding Road network analysis of road-ability, is the waste and old material of cement pavement
Expect that regeneration provides technical conditions, be a kind of convenient, saving, safety, the cement concrete pavement maintenance process of high-quality.
