Non‑carrier joint sealing tape is self‑adhesive asphalt crack repair tape for asphalt pavement cracks. Before application, thoroughly clean and dry crack surfaces. Temporary edge lifting may happen from moisture or temperature change, which will disappear after vehicle compaction. Choose proper grade matching local ambient temperature for best sealing performance.
