Ultrathin Asphalt Paver DGT900

Home » Products » Asphalt Road Construction Equipment » Ultrathin Asphalt Paver DGT900

The self-designed DGT900 ultrathin asphalt paver is a professional equipment for the preventive maintenance of highway asphalt pavement. It can pave ultrathin asphalt layer for road maintenance, and can work as a normal paver. The integrated function of modified bitumen emulsion spraying system makes it more excellent.

Main Features
1. The asphalt paver is equipped with engine, power divider, hydraulic pump, valve and motor. It features of high reliability and high working stability.
2. Adopts hydraulic track crawling system, which makes this paver with steady moving, high paving speed, and wide speed-adjusting range.
3. Unique auger system and iron plate design can prevent the material stacking and achieve the road surface with high flatness and density.
4. Equipped with powerful electrical heating system, iron plate and vibrorammer, the asphalt in this asphalt paving equipment can be heated up immediately.
5. The bitumen emulsion spraying module adopts pulse-type spraying way, which has wide adjusting range. The spraying system adopts electrical and thermal oil heating techniques, it can be heated quickly and avoid the blockage of nozzle and pipeline.

Advantage of Ultrathin Paving Technology
1. Renews the surface of road.
2. The service life of ultrathin asphalt concrete wearing layer reaches 8-10 years.
3. The wearing layer surface is rough that can increase the skid resistance of wheels.
4. With low noisy, good water permeability, so the road surface after paving it by our ultrathin asphalt paver which can reduce the water mist in the rainy day, and improve visibility.
5. The wearing layer comes with 2cm thickness, it can extend the road service life after paving it on the old asphalt pavement.
6. It has the short construction cycle, the traffic will be recovered after only 20 minutes which needs to pave the road.

Other Products
  • Mobile Asphalt Rubber Blending Plant Specially designed to produce crumb rubber modified asphalt (asphalt rubber-AR), the mobile asphalt rubber blending plant consists of two main components: a mobile mixing unit and a mobile reaction tank. The former is used to initially mix ground rubber with hot asphalt, while the latter agitates and stores the mixture.
  • Asphalt Emulsion Plant The asphalt emulsion plant is specially designed to produce asphalt emulsion and modified asphalt emulsion. An acid-resistant lining-fluorine centrifugal pump is adopted as the emulsion pump, which has a long service life. The rotation speed of asphalt pump and emulsion pump is controlled by the frequency control system, which is accurate and highly efficient.
