Dynapac North America Launches New Spray Paver SD2500CD PROTAC
Dynapac North America, Fort Mill, South Carolina, in collaboration with sister company Secmair, is launching a new spray paver labeled the SD2500CD PROTAC. It is designed to apply the emulsion and asphalt pavement mix in a single operation. The manufacturer states it is primarily designed for two application areas. The first is for the application of thin asphalt surface layers using “thin layer in hot paving on sealant.” The second is for road repair, as well as for new road construction and everyday asphalting tasks.
The spray paver has a basic width of 8.4 feet and its maximum spray width is 6.5 meters. The 25 independent nozzles are automatically activated by moving the spray bar or extending the screed. The Dynapac spray paver can hold up to 555 gallons (2,100 liters) of emulsion and is equipped with a filling neck and level display on each side. The combination of heating mats and a heating rod with a total heating capacity of 18 kW ensure gentle, yet rapid heating, according to the manufacturer. The heating mats are designed to prevent separation of the emulsion. Even smaller amounts of 26 gallons in the tank can be warmed up, according to the manufacturer. Both the heating rods and the heating mats are controlled automatically.
