Crack tape manufacturers explain that crack tape is made of asphalt-based high polymer, high tensile strength base fabric, and high-temperature-resistant fabric that is compatible with asphalt. When applied to asphalt concrete surfaces with cracks or spalling, it reduces and isolates the thermal contraction stresses acting on the road surface, thereby also reducing the tendency for cracks to reflect through the surface layer. Laying it on the road isolates the sub-layer from the upper wearing course, thus protecting the upper layer from multidirectional displacement and shearing stresses, and it is used for highways, bridges, airports, and more. The crack tape can withstand tensile stresses from cracks. When the tensile stress from the cracks increases and exceeds the tensile strength of the crack tape, the tape begins to deform. It is at this point that the surface layer starts to accept the tensile stresses transmitted from the crack tape, thereby stabilizing the tensile strength of the road structure layer.
Crack-bridging tape can be used for interlayer crack treatment, such as when converting white cement roads to black, first seal the road cracks and expansion joints, then use the crack-bridging tape for overlay adhesive application to absorb stress and prevent crack reflection. For example, in the treatment of cracks on asphalt concrete roads after milling, the principle is the same.
High-temperature resistant fabric on the surface of the crack-bridging tape boasts significant tensile strength, effectively resisting interlayer tensile stress, constraining the expansion of crack width, and reinforcing the structure. It stabilizes the tensile strength of the asphalt pavement's structural layers. It also serves as a damping buffer. Therefore, it is quite effective for interlayer crack treatment.
The polymer in the crack-bridging tape is a viscoelastic material with low-temperature flexibility. Treating interlayer cracks with the crack-bridging tape is equivalent to setting up a composite layer that remains viscoelastic under certain low temperatures. The tensile stress at the crack is gradually expanded and dissipated through the viscoelastic composite layer, effectively absorbing tensile energy.
