Asphalt Crack stickers waterproof stickers

Crack paste (also known as crack paste) is a polymer asphalt-based, high-strength tensile tread base, high temperature and high strength fabric compatible with asphalt composite. Attach it to cracks or peeling asphalt concrete surface, and blocking it can reduce the temperature compressive stress acts on the road, and therefore reduce the crack reflection through the surface layer of the trend, the laying of the road because of the grass-roots level with the upper wear layer isolated, so that the top layer from much displacement and shear stress effect, for roads, bridges and airports. The main performance 1, isolation. Laying crack paste the crack surface layer and asphalt surface isolation, avoid direct contact with the asphalt surface cracking level of grassroots tensile stress fracture can not be passed directly to the asphalt concrete surface layer, although reducing the base layer and the surface layer the binding force between, but stick to make the upper and lower polymer cracking good adhesion into a whole, have to bear the effect of vehicle load, sufficient to prevent relative displacement of the upper and lower screen while maintaining continuous. 2, reinforcement effect. When crack paste has a certain strength, can withstand a certain tensile stress fracture, the tensile stress is increased when the crack and the tensile strength of greater than crack paste, paste cracking start to deform, when the surface layer began to crack bear stickers transfer up tensile stress. Cracking posted levels will bear all the tensile stress fractures, apparently reinforced crack paste play a role in this sense, it increases the tensile strength of the pavement structure layers. 3, energy dissipation buffer. Crack paste material having a certain extensibility, polymers have good low temperature flexibility, laying asphalt pavement, the equivalent of setting up an elastic layer, the base layer tensile stress fracture extended through the crack attached to the polymer a wider range, and thus relieve the stress intensity at the crack between the elastic layer can play the role of energy absorbed partially drawn. 4, drain seepage effect. Cracking stick polymer capable of forming a complete impermeable barrier layer, can cut off water to the embankment road penetration, thus protecting the grass-roots strength, so that base material properties will not deteriorate further. Paste used in asphalt pavement cracking can be effectively suppresses the transmission of cracks up to play the role of crack cracking stickers and absorbing role in the actual project.
