Cracks also related to the following reasons: the construction factors: mainly refers to the water content after rolling semi-rigid material, semi-rigid base to complete the exposure time and other factors; unevenness fill and fill material, and Fill density of less than the design requirements. After a period of natural settling, especially after rain soaked roadbed strength decline, also fell along part of the roadbed slope bearing capacity, there will be longitudinal cracks; construction, cold joints connecting pieces at the front paving fails the relevant regulatory requirements seriously, combining not close and disengaged. Stickers seam tape use: 1, construction steps were: Crack cleaning or purging, tear film paste, artificial compaction; 2, keep the surface clean and dry cracks paste seam zone Which is good, construction should remain in cracks and thoroughly clean cracks in the tablets of stone, when the crack width or depth greater than 1cm recommend filling; 3, the product sided lamination, the operator will cement pavement seams with paste, available from any one deposit tear covered with mask construction, when the tear film Note that both sides should be removed skirt covered with cracks paste seam zone, the construction process to avoid contamination by hand and other adhesive surface; 4, the product viscosity, construction Do not artificially force stretching deformation, natural Paste to ensure that the product excellent Sealing performance.
