Asphalt-pavement-maintenance-vehicle-DAY-3031

Introduction

DAY-3031 Asphalt pavement maintenance machine is researched and developed for satisfy the road maintenance requirement. It is mainly applied to accomplish the pavement pothole repairing work on highway.

It is composed of truck chassis, hydraulic system, HMA bin, burning system, asphalt spraying system, control system and vibratory roller etc.

The machine can realize the heat preservation for HMA during transportation, furthermore, can heat up the cold HMA material to temperature 140~160 ℃ and meantime keep heat preservation, which meet the technical request for HMA under various long distance construction, The machine is equipped with asphalt heating and spraying device, heating device is independently controlled, which can be separately heated anytime according to construction requirement. HMA bin introduced the mixing and heating method, which can heat uniformly and completely. The machine can also be used to spray either the asphalt emulsion or hot asphalt on the bottom of the pothole to improve the bonding strength, vibratory roller for further sufficient compaction on patched pavement.
