Description
Technical field
The invention belongs to the asphalt pavement conserving technical field, relate in particular to pressing belt and its preparation method that a kind of asphalt pavement crack is repaired usefulness fast.
Background technology
The crack is one of main disease of flexible pavement, adopts various technological means sealing pavement cracks, and it is inner that anti-sealing infiltrates road structure, extensively thought to slow down the effective means that pavement disease occurs, prolongs service life of road surface in the world.Usually adopting the joint filling or the cementation of fissures to carry out the crack repairs.Filling technology does not expand groove to the crack, directly adopts joint sealing material to fill in the crack, and result of use is relatively poor usually.Slit-pouring Technology is at first slotted and is expanded seam, adopts fluid sealant perfusion crack then, and result of use is better relatively.But also there is certain limitation in Slit-pouring Technology, at first is that the operating efficiency of the fluting cementation of fissures is very low, is difficult to satisfy the requirement of repairing road surface at quick speed; Next is to slot to bring easily afterwards to gnaw limit, the sick evil of latasuture grade, and the highway section aging more serious on the road surface is all the more so.
Pressing belt (also claiming affixing kerfs belt, joint filling band) is a kind of novel crack patching material.The operating principle of pressing belt is through external force extruding strip material dead-end fracture.The technology that adopts pressing belt to carry out the pavement crack repairing is called the tooled joint technology; This technology does not need the road pavement crack to slot; Only need simply clean fracture faces and get final product, and have very high operating efficiency, and can not produce the secondary disease that fluting causes.Therefore, the tooled joint technology has remedied the deficiency of Slit-pouring Technology preferably, and pressing belt becomes a kind of novel crack fast repairing material of rising in recent years.
At present, the domestic manufacturer who has some provides the pressing belt product.But the quality of these pressing belt products is uneven, and this has restricted the application of this material in transportation industry to a great extent.Pressing belt has at the main failure phenomenon that use possibly occur: come off and ftracture.Coming off possibly be material in summer because high-temperature behavior is not enough, and rubber modified asphalt class encapsulant is clamminess, and is taken away by tire; Also possibly be material embrittlement hardening in the winter time, lose the adhesive property surperficial, taken away by tire with flexible pavement.Cracking is material embrittlement hardening in the winter time, the low temperature poor ductility of material, in the process of expansion of crack by drawing crack.With regard to present domestic material commonly used, the cryogenic property deficiency is the main cause of material failure.
Therefore, this area also needs the pressing belt that a kind of low temperature bonding performance is good, low temperature ductility is good, crash rate is low.
Summary of the invention
The purpose of this invention is to provide the asphalt pavement crack that a kind of low temperature bonding performance is good, low temperature ductility is good, crash rate is low and repair the pressing belt of usefulness.
The present invention provides a kind of asphalt pavement crack pressing belt, and it is made up of first separation layer, self-adhesive layer, composite layer and second separation layer in order.Wherein, said composite layer is by the moulding of bituminous seal material soaking fibrous material.Wherein, Said bituminous seal material is composed of the following components by weight percentage: said bituminous seal material is composed of the following components by weight percentage: 100 parts of modified bitumens, rubber powder 20-40 part, softening agent 5-20 part; Plasticizing agent 2-10 part; Film forming agent 2-10 part, tackifier 8-20 part, mineral filler 5-15 part.
The composite layer of asphalt pavement crack pressing belt of the present invention contains the fibrous material of bituminous seal material soaking, and said fibrous material provides skeleton to pressing belt, gives pressing belt shape, ductility and thickness.The fibrous material that can be used for the asphalt pavement repairing purposes comprises wood fibre and synthetic fibers.Wood fibre is the organic wadding fibrous material that natural reproducible timber obtains through chemical treatment, Mechanical Method processing.Wood fibre to prevent coating cracking, improve water retention, improve the stability of producing and construction conformance, gain in strength, strengthen the adhesive power on surface etc. is had good effect.Synthetic fibers comprise polyester fiber, polypropylene fibre and polyacrylonitrile fibre fibrous material etc.The fibrous material that uses in the present invention comprises synthetic fibers.
The linear polymer that synthetic fibers are synthetic with manual work, have suitable molecular weight and have solvable (or fusible) property, the chemical fibre that makes through spinning technique and post processing.The line style organic high molecular compound that can form synthetic fibers comprises polypropylene, polyester, polyamide etc.
Fypro is also claimed nylon or polyamide fibre, is to be raw material with the polyamide, promptly contain on the molecular backbone recurring amide radical group-[NHCO]-the thermoplastic resin general name.Comprise fatty polyamide, aliphatic-aromatic polyamide and aromatic polyamide.Nearly tens kinds of Fypro kinds commonly used, wherein the application with polyamide-6, polyamide-66 and polyamide-610 is the most extensive.The link configuration of polyamide-6, polyamide-66 and polyamide-610 is respectively [NH (CH
2)
5CO], [NH (CH
2)
6NHCO (CH
2)
4CO] and [NH (CH
2)
6NHCO (CH
2)
8CO].Polyamide-6 and polyamide-66 is mainly used in the spinning synthetic fibers, is called polyamide fibre-6 and nylon-66.
Polyester fiber is also referred to as terylene, is to be the general designation of the obtained fiber of raw material by multiple dihydroxylic alcohols and aromatic binary carboxylic acid or its ester through the polyester that polycondensation generates.Common kind has: dacron fibre, poly fiber, polytrimethylene terephthalate fiber; Poly terephthalic acid-1,4-hexamethylene dimethyl ester fiber gathers-2; 6-naphthalene diacid second two ester fibers; And the dacron fibre of multiple modification (as: CDP, ECDP, EDDP) etc.The most frequently used is dacron fibre.
