It is internal;Under serious conditions, patch can be caused to stitch if water ratio limit power is insufficiently resistant to the long term of Tire Friction, in the short time
The sliding of band falls off, and loses its water-proof function.Meanwhile there is finished product affixing kerfs belt fixed width and larger thickness, road table to split
When seam moves towards irregular, stickup overlap joint processing is cumbersome, the phenomenon that part waterproof is omitted inevitably occurs;Also have using the expansion slot cementation of fissures
Method of squeegeeing, but be easy to cause and gnaw side isostructuralism damage hidden danger, and source consumption is big;In addition, heat construction material is squeegeeed
It will produce toxic and harmful gas in work progress, the health of construction personnel damaged, while also polluting the environment, and
And high labor cost, equipment investment is big, leads to problems such as construction cost higher.
Therefore, it is necessary to a kind of novel room temperature constructions to squeegee with waterproof paster, and overlap joint is convenient, strong with road surface cohesion, can
The telescopic deformation in gap is adapted to, leakproofness and good water-proof effect, durability are strong.
