Product Description:

Crack stick construction

Anti-crack construction effect

Crack stick

Product introduction

Crack stick (also known as crack stick) is composed of asphalt base polymer, high-strength tensile tire base, high temperature resistance and compatibility with asphalt high-strength compounded fabric. Stick in the cracks or the spalling of the asphalt concrete surface, can reduce and cut off its effect on the temperature shrinkage stress of pavement, thus reduce the reflection crack through the surface of the trend, laying and road because of the isolates abrasion at the grass-roots level and the upper layer, so that the top layer from the effects of multidirectional displacement and the shear stress, for roads, Bridges, airports, etc.

The main performance

1, the isolation effect. Laying crack and the crack surface and asphalt layer isolation, to avoid the direct contact with asphalt layer cracking level, crack tensile stress at the grass-roots level cannot directly transfer the asphalt concrete pavement, reduce the bonding force between the base and surface, but polymer anti-crack stick can enable the lower level very good adhesion into a whole, jointly bear the role of vehicle load, is enough to prevent the interface on the lower level of relative displacement and keep continuous.

2, reinforcement effect. Crack has a certain strength, can absorb a certain amount of tensile stress in the crack, when the crack tensile stress increases and is greater than the crack of tensile strength, crack resistance to deformation, the surface began to crack under the tensile stress in the stick to pass up. Crack stick level will bear all the tensile stress in the crack, crack obviously have the effect of reinforcement, in this sense, it improved the tensile strength of pavement structure layer.

3, energy dissipation cushion. Crack is a certain extensibility of material, high polymer has good low temperature flexibility, laid between the asphalt surface, equivalent to set up an elastic layer, crack tensile stress at the grass-roots level through the anti-cracking polymer spread to a wide range, so as to relieve stress intensity cracks, flexible interlayer can partly tensile energy absorption effect.

4, water seepage control effect. Crack stick seepage-proof layer polymer can form a complete, can partition to the subgrade pavement water penetration, in order to ensure the strength of the base, the base materials properties not deteriorate further. Crack stick for asphalt surface can effectively inhibit cracks propagated up, in the practical engineering play a role of crack resistance of crack and energy absorption effect.
