Description
Technical field
The present invention relates to Road maintenance, repairing technique field, particularly composite cold feed supplement preparation method for a kind of asphalt pavement pit repairing.
Background technology
Hole groove is one of common typical disease of bituminous pavement, can have a strong impact on the planeness on road surface and the comfortableness of driving.Process timely if can not get, under the comprehensive action of traffic loading, weather, water etc., destroy and continue development, consider from security standpoint, can cause great threat to driver and crew's personnel safety; Consider from economic angle, the continuation development of hole groove also makes being multiplied of maintenance costs.
Pit repairing is mainly repairing and the reinforcement for diseases such as hole groove, local check crack, be full of cracks, but also can be to local subsidence, gather around bag and slumping crack is repaired.Carry out at present pit repairing and mainly contain two kinds of techniques: cold-patch and vulcanizing.Cold-patch and the performance of vulcanizing and feature contrast are as shown in table 1
Table 1 cold-patch and the performance of vulcanizing and feature contrast
It is very outstanding that cold-patch material is vulcanized material advantage relatively, but existing cold-patch and the maximum weak point of vulcanizing material be exactly poor with former road surface consistency after forming materials, later strength is little, the life-span is not long.Therefore the present invention propose invention a kind of good with former road surface consistency, later strength is suitable with bituminous pavement, the compound cold-patch material of pit repairing that the life-span is grown.
The main forms that hole groove destroys is divided into following three kinds:
Upper layer produces hole groove.Cohesive force because asphalt uplayer compound local porosity is large, between pitch and building stones is not strong, road table water enters and is trapped in upper layer asphalt, under traffic load especially heavy load constantly acts on, the hydrodynamic pressure producing makes the pitch of upper layer get off from building stones surfacial spalling, and bituminous pavement just can produce local loose destruction.The building stones that are scattered are thrown away by wheel, and road surface forms hole groove from top to bottom, and the degree of depth of this class hole groove is generally 2～5cm, and in Chinese Protective Measures of Bitumen Pavement Initial Damage, all kinds of holes groove produces the earliest, is also to produce the maximum class of quantity.
Upper layer and middle surface layer produce hole groove simultaneously.When bituminous pavement upper layer and middle surface layer are all the half open gradation asphalts that voidage is larger, and when the bottom surface layer dense bitumen compound that to be voidage less, the free water of road table is more easily infiltrated and is trapped in upper layer and middle surface layer.Asphalt stripping during the effect of driving load makes, in upper layer, asphalt loses cohesive strength, causes road surface produce check crack, deformation (local falling into enemy hands) and push laterally, and finally occurs that pellet separates.The pellet effect of being driven a vehicle takes away, the final hole groove that forms, and the degree of depth after this type of hole groove is completed into is generally 8～10cm.
Between bottom surface layer and basic unit, produce hole groove.This type of disease easily occurs in the frost boiling very serious road surface of phenomenon, and under heavy-duty vehicle effect, the pressure that free water produces washes away base mixture top layer fines, forms greyish white mill base.Under the repeated action of hydrodynamic pressure and pore water pressure, make the base-material particle appearance in whole surface layer loose, and reflex to surface layer, form vicious cycle, finally can cause cheating the appearance of groove.The degree of depth of this type of hole groove is generally greater than 10cm.
Summary of the invention
For the defect existing in prior art, the object of this invention is to provide a kind of good with former road surface consistency, later strength is suitable with bituminous pavement, the compound cold-patch material of asphalt pavement pit repairing that life-span is grown, this kind of technological deficiency that material can overcome existing hole groove cold-patch, vulcanize material.
The present invention adopts following technical scheme:
A kind of for the compound cold-patch material of asphalt pavement pit repairing, be prepared from according to the ratio of weight and number of 1: 1 by A component and B component; Described A component and B component are made up of following raw materials by weight portion:
A component:

Surplus is water.
On the basis of such scheme, described pitch is any one in heavy-duty road bitumen A H-30～AH-90.
On the basis of such scheme, described cats product is one or more the mixture in alkyl polyamine class, quaternary ammonium salt, alkyl imidazoline salt, alkyl pyridine salt, amide group amine or lignin.
On the basis of such scheme, described water reducer is one or more the mixture in polyocarboxy acid type, naphthalene type, aliphatics type or amino-type.
On the basis of such scheme, described defoamer is one or more the mixture in silicone based, mineral oils, polyethers or aliphatic alcohols.
On the basis of such scheme, described binding agent is one or more the mixture in water-borne acrylic resin, aqueous epoxy resins or SBR latex.
On the basis of such scheme, described swelling agent is one or more the mixture in calcium sulphoaluminate class, calcium oxide-calcium sulphoaluminate class, calcium oxide or aluminium powder.
On the basis of such scheme, described pH adjusting agent is one or more the mixture in hydrochloric acid, phosphoric acid or acetic acid.
On the basis of such scheme, described cement is one or more the mixture in cement PO32.5, PO42.5, PO42.5R or PO52.5.
On the basis of such scheme, described sand is that particle diameter is the quartz sand of 0.15-0.25mm.
Prepare the above-mentioned method for the compound cold-patch material of asphalt pavement pit repairing, concrete preparation method is as follows:
1) preparation of A component:
Take according to quantity each component in A component, by cats product, water and pH adjusting agent, mix, by mixeding liquid temperature control temperature at 45-60 DEG C, then asphalt heating is arrived to 130-150 DEG C, and after adopting emulsified bitumen colloidal mill (3000-10000rpm) processing 2-2.5min with above-mentioned mixed solution, obtain cationic emulsified bitumen, cooling after and water reducer, defoamer, binding agent and water and cement, sand and swelling agent in mortar mixer, stir 5min and obtain A component;
2) preparation of B component:
Take according to quantity each component in B component, and each component is stirred in stirrer;
3), while construction, on-the-spot A component and B component A and the B of evenly mixing mixes according to the ratio of weight and number of 1: 1, fills out immediately and cheats construction, fills out compacting behind hole.
A kind of as above for the compound cold-patch material of asphalt pavement pit repairing, described compound cold-patch material is for Reparation of Bituminous Pavement hole groove, the degree of depth≤9cm of hole groove; As hole groove depth≤9cm, just upper layer and the middle surface layer on road surface are damaged, and the destruction of base layer structure does not occur.
The invention has the beneficial effects as follows:
Utilize the liquid fluidity of emulsification asphalt cement mortar, mix large particle diameter aggregate, after curing molding, form a kind of novel compound pit repairing material, this material can embody the malleable of pitch, can embody again the rigidity characteristics of cement material, the own intensity of the intensity after this kind of pit repairing forming materials and road surface is suitable, and the adhesive property that can improve material that adds of binding agent makes this material and former road surface have good consistency.
