Self Adhesion Bituminous Tape to Repair Asphalt Road Crack
1. Description
ZT-Crack Tape is a self-adhesive, cold-coated, polymer-modified high-viscosity bituminous tape. It is a new type of highway maintenance material which specially deals with the cracks of asphalt and cement concrete pavement. It provide an instant seal and prevent further deterioration of the road pavement.
2. Specification
After strictly selection of materials, our company is equipped with a full set of testing equipment to test raw materials and products to ensure that products can meet industry standards and meet customer needs. The applicability test of nearly 1.5 million meters across the country has been widely recognized for its performance.

1. Cold type
It has high viscosity and strong stickiness and mainly used in cold areas. It is more suitable for winter construction, with low temperature stretching can reach more than -30 degrees, and used at a temperature of about 0 to 15 degrees. Especially suitable for temperate and frigid countries and regions.
2. Warm type
It has a lower viscosity than winter type and mainly used in areas with high temperatures. It is used at a climate temperature of above 15 degrees. Especially suitable for tropical and subtropical countries and regions in the equatorial region.

4. Features of self adhesion bituminous tape to repair asphalt road crack
1). High self-adhesive strength:No need for any equipment compaction, just simple manualfoot pressing to open the traffic and not fall off easily.
2). Energy saving and environmental protection: no heating, no energy consumption, no emissions, especially for the daily maintenance of municipal roads has obviousadvantages.
3). Wide temperature range. It can be used all year.
4). Good flexibility. It can turn freely along the crack.
5). Adopting single-sided coating, the construction efficiency is improved, and the single-person operation can reach 2 meters / minute.
6). Excellent performance: repeated action of traffic loads, most of the adhesive tape material will be embedded in the crack. The mechanism of action at this time is exactly the same as that of the sealant, and has equivalent road performance.
7). Multiple uses. It is not only used for crack treatment, but also for rapid treatment of road cracks, pit prevention, and bridge expansion joint concrete protection and so on.
