Cracking paste 25kn12kn

Reason can: crack paste is a high strength, high elongation, high adhesion active waterproof material, the net thickness of 2 mm or more, can effectively improve the pavement cracking waterproofing properties. The geotextile is suitable for single permeable or impermeable fabric earthworks, generally very thin, less than 1 mm, rupture strength, elongation and elasticity is low, is not suitable for use as a base waterproof material. 2 Chemical properties: Cracking paste is a combination of polymer material, chemical stability, excellent anti-aging properties, compared with geotextile have better chemical properties. 3 bond performance: crack paste has a strong bonding capacity, can be directly bonded to clean the grass, while the geotextile itself does not have bonding capacity, it needs brushing emulsified asphalt just have some bonding capacity, sealing effect also poor. 4 elasticity, resistance to deformation ability: crack stick with the "self-healing" capability and strong resistance to deformation, will not break or crack tearing up and down in the grass when dislocation. The geotextile cloth and this inelastic deformation capacity, it is prone to cracking in the cracks occurred when grassroots dislocation. 5 Anti-lapse capability: Because the laying of geotextile width generally about 1m, and both upper and lower geotextile spraying emulsified asphalt, after the paving surface, the sliding surface layer and a base layer is formed without connectivity laying geotextile below layer, with the wheels rolling geotextile will be laid at the direction transverse passage, but on the road to form a similar surge reduction with the same package, seriously affect driving safety and comfort. Cracking posted only laid stress concentration cracks, general width of not more than 22cm, and crack paste has a strong elasticity, asphalt and aggregate will be a certain degree of crack paste mosaic, not easy in the anti- cleft stick surface of the slider, it will not cause a lateral passage. 6 Waterproof: crack paste mainly for stress concentration at the crack and the crack seal, forming a stop, and the role of geotextile is a face, but not particularly strengthen the cracks, forming a weak link in the cracks, easy cause damage, breakage, poor adhesion, water seepage phenomenon. 7 construction performance: Cracking paste convenient construction, construction of cold without heating, one that is prison. In laying geotextile first spraying emulsified asphalt can be laid after breaking, laying before spraying emulsified asphalt and paver work when it is easy to bring up the geotextile, geotextile will lift rolling in face layer and cause problems. 8 high temperature, low temperature resistance properties. : Cracking posted mainly by the polymer composition, with good high temperature performance, but also has a certain thickness, and grass-roots also form a good bond, can also play a role in cooling paving surface layer, although the asphalt When the mixture at high temperature nor will lay the instantaneous crack paste damage, but it is inferior 布尤 geotextile geotextiles are easily deformed at high temperatures or melting useless.
