Many highway contractors face recurring troubles during routine pavement maintenance. Manual crack pouring wastes plenty of manpower, brings uneven filling depth and leads to frequent rework after short-term road use. For long-distance expressway crack treatment, choosing a matched professional crack filling machine becomes the most cost-saving construction option.
Tongda Highway has focused on road maintenance equipment development for over 20 years, designing multi-spec crack filling machines customized for highway, municipal and trunk road crack repair projects. Our self-propelled crack filling machine comes with constant-temperature heating system, which keeps hot pour asphalt sealant at stable working temperature during all-day outdoor construction, avoiding material coagulation and pipeline blockage that commonly happen with inferior equipment.
When working on long-section highway cracks, operators can adjust the 360° rotatable discharging nozzle flexibly to fit narrow transverse cracks and wide longitudinal cracks on asphalt pavement. Compared with traditional hand-held filling tools, this road crack repair equipment improves construction speed by more than double and reduces material waste effectively.
All Tongda crack filling machines adopt thickened manganese steel body to stand bumpy highway construction sites, greatly cutting down breakdown frequency during continuous high-intensity operation. Apart from finished standard models, we support personalized size adjustment to satisfy different regional highway maintenance standards around the world.
