DAY-3021 Asphalt pavement maintenance

DAY-3021 Asphalt pavement maintenance is an advanced and high efficient road construction equipment which can spray bitumen and spread chippings at the same time. It is a new generation with international standard and high technological chip sealer, developed on the basis of foreign technique and practical situation in China.


  • 1.Spreading quantity of asphalt and crushed stones is intelligently controlled. Spraying of asphalt and crushed stones is controlled with one key;
  • 2.The chip distributing mechanism is designed with good compactness, and the opening extent of the material gate may be controlled through the manual rotor disc.
  • 3.Spreading quantity of asphalt and crushed stones is intelligently controlled. Spraying of asphalt and crushed stones is controlled with one key;
  • 4.The burner dry burning-resistant safety device and heat conduction oil temperature monitoring system are first developed. The heating is safer and more reliable.
  • 5.Heat conducting oil circuit to keep all the pipelines and pumps unblocked.


It is provided with the advantages of costing saving, surface wear resistance, slip resistance, water resistance, and quick traffic recovery when construction is completed. It is applicable to the construction of highways of different grades.
