Abstract
Asphalt pavement rut Treatment Methods under the conditions of not suspended the invention discloses one kind, using rigidity plus flexible through thickness recovery scenario, first the bituminous concrete through thickness in rut disease region is cut off, and basic unit's cement concrete surface is carried out into dabbing treatment, then cutting optimal pours rigid material for quickly repairing, and upper layer making heat mixes modified asphalt mixture to former grade elevation.The method of the present invention not only reduces bituminous concrete thickness, and modified asphalt mixture has excellent combination property, can effectively, quickly solve the problems, such as asphalt pavement rut, and the airfield pavement effect thicker to asphalt concrete layer is particularly evident.
Description
Technical field
The invention belongs to asphalt concrete pavement recovery technique field, bituminous concrete road under the conditions of being related to one kind not suspend
Face rut Treatment Methods.
Background technology
At present, civil airport asphalt pavement rut disease never has and is controlled very well.In movement area asphalt pavement, fly
, easily there is rut, influence road face operation safety in the slow region of machine sliding speed, aircraft holding fix.
The processing method of common airfield pavement rut mainly has two kinds：The first is treatment, that is, exclude top layer 5~
7 centimetres, then overlay to Yuan Dao faces absolute altitude；This kind of method treatment thoroughly, does not easily continue rut occur in very short time road face.The
Two kinds is through thickness treatment, but because airfield runway can be generally less than 8 hours the engineering time, causes it to divide by standard requirement
Layer construction, construction quality cannot often ensure, it is impossible to fundamentally solve the problems, such as rut.It is therefore proposed that one kind is more effectively, soon
The asphalt pavement rut Treatment Methods of speed are into the task of top priority.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, there is provided one kind do not suspend under the conditions of at asphalt pavement rut
Control method, using rigidity plus flexible through thickness recovery scenario, reduce asphalt pavement thickness degree, can it is fundamentally quick, have
Effect ground solves the problems, such as rut, is particularly well-suited to asphalt pavement thicker, the serious Airport Asphalt of rut problem of layer.
The main technique of rut Treatment Methods proposed by the present invention comprises the following steps：
Through thickness is first carried out to the asphalt concrete pavement in rut disease region and abolishes cleaning, form bar shaped pit；Then
Rigid material for quickly repairing is first poured in bar shaped pit, pouring preceding substrate need not sprinkle water wetting, pour, vibrate, plucking it is complete
After into 1 hour again thereon making hot-mix asphalt mixture to former grade elevation.
Concrete construction method can be as follows：
1st, cleaning is abolished in rut region
Through thickness is carried out to asphalt concrete pavement to abolish, i.e., first use and cut by the way of " sawing+pick crusher machine "
Cutting mill perpendicular cuts go out repairing area, and depth of cut is asphalt concrete pavement thickness；Then using pick crusher machine and remove
Totally；Dabbing treatment is finally carried out to basic unit's cement concrete surface using dabbing machine, then is cleaned out and to be formed bar shaped pit.
2nd, rigid material for quickly repairing is poured
Rigid material for quickly repairing is directly poured in bar shaped pit, pouring preceding substrate need not sprinkle water moistening, pour, shake
Smash, making upper layer hot-mixed asphaltic concrete by 1 hour after the completion of plucking.
Existing material for quickly repairing mainly have phosphate cement class, sulphate aluminium cement class, fluoroaluminate cement class and
Organic polymer class；Wherein, sulphate aluminium cement class and fluoroaluminate cement class adhesive property are poor, it is impossible to be combined into basic unit whole
Body, organic polymer class is (such as：Epoxy resin) there are excellent adhesion strength, but its non-refractory, elastic modelling quantity, thermal coefficient of expansion
Differed greatly with base material, it is easily aging.Rigid material for quickly repairing of the present invention is phosphate cement concrete, its morning
Phase intensity is high, good with basic unit bond effect.
3rd, making heat mixes modified asphalt mixture
Sticking layer oil is spilt in cement concrete surface, pave modified asphalt mixture；Pave to designed elevation, first laterally grind
Pressure, longitudinal direction fully compacting, makes it be connected smooth-going with former road surface afterwards.
Described modified asphalt mixture is close by the modifying agent such as high-modulus asphalt, rut agent, the skeleton that constitutes such as gather materials
Full mold Modified Bitumen SMA Mixture, it has excellent high-temperature stability (anti-rut ability), low temperature anti-cracking performance, water steady
Qualitative energy, antiskid performance and anti-fatigue ability；Thickness is 5~7 centimetres after described modified asphalt concrete roller-compaction.
The beneficial effects of the invention are as follows：The method of the present invention not only reduces bituminous concrete thickness, and entirely constructs
Process is simple, efficient, quick, can effectively, quickly solve the problems, such as asphalt pavement rut, the airport thicker to asphalt concrete layer
Road face effect is particularly evident, it is ensured that rut disease is punished under the conditions of not suspending；And bonded by force using with excellent
The material for quickly repairing phosphate cement concrete and framework compact type Modified Bitumen SMA Mixture of degree and early strength, can make
It is combined into an entirety with substrate concrete, so as to effectively solve rut disease.
