Tongda
Product Description
Tongda net crack sealing tape is mainly used in road surface mesh cracks. Due to the roadbed hardness is not enough, the surface material ratio is not normal, the surface material density is not enough, high quality vehicular heavy load and other reasons, the road surface has regular criss-cross cracks (local or small area area with a certain density of irregular cracks). Net crack sealing tape seam by manual or mechanical way directly paste covering on the network crack site, through the rolling can achieve the purpose of fast repair of local network crack road surface.
Application
Various grades of asphalt concrete pavement for longitudinal and transverse cracks repair.
It can be used for the crack repair of asphalt road, cement pavement, concrete road surface and even airport runway.
