Common Pavement Crack Types & Targeted Repair Solutions With Crack Filling Machine

Different crack shapes on asphalt and concrete pavement require differentiated repair crafts and supporting construction equipment. Longitudinal cracks, transverse cracks and block cracks account for most pavement damage on domestic and overseas highways, and improper filling method will accelerate pavement base erosion by rainwater infiltration.

Long cracks extending along highway direction need large-volume continuous feeding via self-propelled crack filling machine. The constant-temperature tank ensures sealant fluidity to fill crack depth completely and block underground water intrusion. Short scattered transverse cracks on municipal road sections can be quickly handled with small portable crack fillers, greatly shortening road occupation time and reducing traffic disturbance.

For aged block cracks formed after years of highway operation, construction teams usually combine cold patch asphalt and hot poured sealant: fill sunken damaged areas with cold patch first, then use crack filling machine to seal peripheral split gaps comprehensively. This composite repair method effectively prolongs pavement service life by 5~7 years.

Tongda Highway summarizes mature construction schemes based on thousands of global road projects, combining our self-produced crack filling machine and road sealant to form complete road maintenance solutions.
