Description
Technical field
The invention belongs to the LB mending technique field, be specifically related to a kind of road surface affixing kerfs belt and preparation thereof, constructional method.
Background technology
The crack be the most common in all kinds of breakages of bituminous pavement, the most easily occur, one of disease that very early time produces, it almost is accompanied by the whole usage period of bituminous pavement, and increases the weight of along with the growth in road age.The crack appears in the road surface not only affects the comfortableness that the appearance of a street is attractive in appearance and drive a vehicle, and easily expansion causes the structure deteriorate on road surface and shortens the work-ing life on road surface.The crack appears in bituminous pavement should in time fill out the envelope repairing, otherwise rainwater and other foreign material will enter the Sub structure and roadbed along the crack, causes the road surface supporting capacity to descend, and accelerates part, road surface or in flakes damage.
The crack treatment of bituminous pavement adopts joint filling or the cementation of fissures to carry out crack repairing usually at present.Filling technology not fracture expands groove, directly adopts seam sealer to fill in the crack, and speed also can not damage original road surface, but result of use is generally relatively poor.Slit-pouring Technology at first road pavement crack is slotted and is expanded seam, then adopts seal gum perfusion crack, and result of use is relatively better.But also there is certain limitation in Slit-pouring Technology, at first is that the working efficiency of notch and fill slot is very low, is difficult to satisfy the requirement of repairing road surface at quick speed; Next is to slot easily to bring 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.
Because the notch and fill slot operating efficiency is low, cause measure expense cost in the construction process far above the priming cost of construction itself.Add heat request in large, the cementation of fissures process of dust in, the fluting purge large to traffic impact simultaneously high, therefore need to seek more fast and convenient bituminous pavement treatment technology.
The at present domestic product innovation that the crack fast processing occurred partly can carrying out comprises affixing kerfs belt, anti-splitting paster etc.
The technology that adopts affixing kerfs 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 the fracture surface simply to clean and get final product, have very high working 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, becomes a kind of novel crack fast repairing material of rising in recent years
At present, domestic affixing kerfs belt product category is various, but ubiquity cohesiveness is strong, low temperature cracking resistance can not enough problem, thus cause come off, the phenomenon such as cracking, especially particularly serious in these phenomenons of northern area.Studies show that the appearance of these problems outside the Pass having with construction technology, mainly is that the deficiency of the performance of material own causes.
Therefore it is reasonable to research and develop a kind of prescription, cohesiveness is strong, repairing quality good, and low temperature cracking resistance is good, and is durable in use, and the road surface affixing kerfs belt that is easy to construct is for working as the required of generation.
Summary of the invention
