Description
Technical field
The invention belongs to technical field of highway traffic, is related to a kind of road and reinforces Treating technology, and in particular to a kind of pitch
Base grouting material and its construction method for reinforcing road.
Background technology
In recent years, advancing by leaps and bounds with communication, paved road mileage are continuously increased, and the volume of traffic rapidly increases, road
Face early disease also increasingly causes the common concern of professional.Bituminous paving and cement concrete pavement are most common two
Kind pavement structure form.After road is open to traffic, various disease forms are will appear from.The most common disease of asphalt concrete pavement
Have：Crack, pit, loose, bellding, passage etc., the common disease of cement concrete pavement has：Crushing shell, crack, plate angle are broken
Split, faulting of slab ends, purt mud etc..
It is trapped in after penetrating into superficial layer due to water on the bottom of superficial layer and the interface of lower floor, therefore in driving lotus for a long time
Under load effect, asphalt membrane starts to peel off from the bottom of surface layer and gradually extend up, with the stripping of pitch on a large amount of rubbles in bottom
Fall, bituminous concrete also just loses intensity so as to produce check crack and deformation.Under Driving Loading, especially in rainfall
Local check crack after neutralization rain on runway can be gradually loose, and loose building stones are thrown away to form pit-hole by wheel.Because pitch mixes
The inhomogeneities of soil is coagulated, pit-hole is always first produced in bituminous concrete voidage larger part, elapsed over time, it will cause road
Face large area is damaged.When water penetrates asphalt surface course and is trapped in semi-rigid type base top surface, under the effect of a large amount of high speed travelings, from
Mortar is formed by the fines that water produces very big pressure and washes away base mixture top layer, mortar presses purt by driving again, by each
The crack (longitudinal and transverse, diagonal crack and check crack) that kind shape differs forms purt slurry to road surfaces., can in the case where mortar quantity is big
Even more serious crack can be quickly formed, in the case where quantity is small, road surface can be made to form check crack or deformation.Road surface somewhere is once
There is mortar purt to go out, check crack and deformation will soon be produced at this, subsequent precipitation is easier to penetrate, and forms vicious circle,
Ultimately result in road surface heavy damage.
The purt mud occurred for punishment road surface and disease of coming to nothing, while avoid opening road greatly big digging, save maintenance cost, note
Slurry punishment is developed rapidly as a kind of fast repairing method.The main nothing using cement mortar as representative of existing injecting paste material
Machine class, and the organic injecting paste material using high polymer and asphaltic base as representative.Cement mortar injecting paste material exist hardening time it is long,
The stability of the slurries such as gain in strength is slow, free settling bleed is poor, it is impossible to effectively pours into slight crack, and uses a period of time
Afterwards, cement mortar is also easy in the case where the dynamic water of Driving Loading washes away, and produces purt slurry.High polymer grouting is organic using bi-component
Material, injection road structure inside produces intensity, but the control of its ratio is strict, it may have certain dilatancy, grouting amount control
It is improper to influence the use of road surface later stage, and cost is higher.
The content of the invention
In order to overcome shortcoming and deficiency existing for prior art, it is an object of the invention to provide a kind of asphaltic base slip casting material

A kind of construction method that road is reinforced using the pitch base grouting material, is comprised the following steps：
(1) determine road structure come to nothing and leakiness region；
(2) road structure come to nothing and leakiness region drills through injected hole and plasma discharge hole；
(3) the pitch base grouting material is injected into injected hole, until asphalt-based material has been observed in plasma discharge hole, is stopped
Slip casting；
(4) treat that asphalt-based material is cooled to normal temperature, construction terminates, open to traffic.
Further, in step (1), determined by the way of including GPR or flexure road come to nothing and leakiness
Region.
Further, in step (2), the diameter in the injected hole and plasma discharge hole is 0.5cm~2cm, and plasma discharge hole presses four
Side shape arrangement, injected hole are located at the quadrilateral middle of plasma discharge hole composition, and the spacing in plasma discharge hole is 1~3m.
Further, in step (3), the injection speed control is in 200~300ml/min.
Further, in step (4), the time that the asphalt-based material is cooled to normal temperature is 30min.
Compared with prior art, the invention has the advantages that and beneficial effect：
