The utility model belongs to technical field of highway maintenance technology, is related to a kind of road surface pressing belt.The pressing belt includes upper protecting film, upper coating, polyester layer, lower coating, tack coat and the lower protecting film set gradually from top to bottom.Compared with prior art, the advantage of road surface pressing belt described in the utility model is：Four layers of waterproof construction are set, i.e., upper coating, polyester layer, lower coating and tack coat play good waterproof action；Upper protecting film and lower protecting film use silicone oil paper, can isolate coating and tack coat, pressing belt is saved space, and keep the adhesiveness of coating and tack coat with rolling and storage；Tack coat has bonds well performance, pressing belt is brought into close contact with highway surface layer, can effectively prevent from forming gap between pressing belt and surface layer and intaking；Coating uses modified waste rubber powder pitch, possesses good low temperature ductility and cracking resistance, can effectively prevent fracture propagation, reduces road surface breakage, prolonging service life of pavement.
Description
Technical field
The utility model belongs to technical field of highway maintenance technology, it particularly relates to arrive a kind of road surface pressing belt.
Technical background
After a certain period of use time, cracking occurs for basic unit causes surface layer formation reflection crack to highway.Crack is bituminous paving
The most common disease of earlier period damage, crack extension causes pavement structure to destroy, and shortens Road Service Life, therefore, crack occurs
It should be repaired in time.At present, crack repairing is generally carried out using joint filling or Slit-pouring Technology.Fracture is not expanded filling technology
Groove, directly fills in crack using joint sealing material, but using effect is poor；Slit-pouring Technology carries out expansion groove first, then using fluid sealant
Crack is irrigated, using effect is relatively preferable, still, its energy consumption is big, cost is high, inefficiency, be difficult to meet Rapid-Repair
It is required that, and pitch heating produces pernicious gas and workmen can be caused damage, and easily brings after slotting in addition and gnaws side, latasuture
Etc. secondary damage.It is, thus, sought for more practical asphalt pavement crack treatment technology.
Pressing belt (also referred to as pressing belt) is a kind of new crack patching material.Pavement crack repair is carried out using pressing belt,
Slotted without road pavement crack, only need counterincision seam surface simply to be cleaned, by the direct paving of pressing belt in pavement crack
On, dead-end fracture is extruded by external force.During operation, operating efficiency is high, cost is low, and will not produce the secondary damage caused by expanding groove
It is bad.It together with pressing belt is fully bonded to road surface, can effectively prevent fracture propagation and rainwater to invade, reduce road surface breakage, extension
Service life of road surface.At present, the problem of pressing belt generally existing low temperature ductility is poor, so that cause the phenomenons such as cracking to occur,
Especially it is particularly acute in northern area.Research shows that material property deficiency causes the generation of these phenomenons.
The content of the invention
To solve problem above, the utility model provides a kind of simple in construction, easy construction, the good road surface of low temperature ductility
Pressing belt.
A kind of road surface pressing belt described in the utility model, the pressing belt includes the upper protection set gradually from top to bottom
Film 1, upper coating 2, polyester layer 3, lower coating 4, tack coat 5 and lower protecting film 6.
A kind of road surface pressing belt described in the utility model, the upper protecting film 1 and lower protecting film 6 use silicone oil paper, can
To isolate upper coating 2 and tack coat 5, make pressing belt can be with rolling and storage.
A kind of road surface pressing belt described in the utility model, the upper thickness of coating 2 is 0.4-0.5mm, the thickness of lower coating 4
Spend for 0.9-1.1mm.
A kind of road surface pressing belt described in the utility model, the upper coating 2 and lower coating 4 are dripped using modified waste rubber powder
It is blue or green.
Component needed for prepared by modified waste rubber powder pitch is as follows：100 parts of pitch, 25-30 parts of shoddy, 2-3 parts of sodium hypochlorite,
3-5 parts of tackifier, 3-5 parts of plasticizer, 3-5 parts of miberal powder；The tack coat 5 contains modified furfuryl alcohol resin；Described tackifier are
Rosin glycerin ester；Described plasticizer is dioctyl phthalate；Described pressing belt preparation method is：Claim according to the above ratio
Material requested is taken, shoddy and sodium hypochlorite are sufficiently mixed and activate 16h after 40 DEG C；Pitch is heated to 175 DEG C -180 DEG C, will
Rubber powder, tackifier, plasticizer, miberal powder after activation pour into progress high temperature mixing in pitch；Modified waste rubber powder pitch cools
After be applied to the two sides of polyester layer 3, form upper coating 2 and lower coating 4 respectively, protecting film 1 pasted in the another side of upper coating,
The another side of lower coating smears tack coat 5, protecting film 6 under being pasted on tack coat 5；Progress is completed after prolonging pressure, cutting, winding
Make.
Compared with prior art, the advantage of road surface pressing belt described in the utility model is：Four layers of waterproof construction are set, i.e.,
Upper coating, polyester layer, lower coating and tack coat, play good waterproof action；Upper protecting film and lower protecting film use silicone oil paper,
Coating and tack coat can be isolated, pressing belt is saved space, and keep the adhesion of coating and tack coat with rolling and storage
Property；Tack coat has bonds well performance, pressing belt is brought into close contact with highway surface layer, can effectively prevent pressing belt and surface layer
Between formed gap and intake；Coating uses modified waste rubber powder pitch, possesses good low temperature ductility and cracking resistance, can
Effectively prevention fracture propagation, reduces road surface breakage, prolonging service life of pavement.
