Page 108: Sprinkling
Operation Sprinkling 3.06 Sprinkling General The pressure sprinkling ensures a reliable moistening of the roller drums / tyres during blacktop works and thus prevents bituminous materials from adhering to the drums. An electric water pump supplies the sprinkling system with water so that the water consumption can be optimally adjusted to the deployment conditions using the installed automatic sprinkling.
Page 109 Operation Sprinkling On risk of frost Frozen water leads to damage to the sprinkler system. Therefore, it must be drained before frost begins. Emptying the water sprinkling system: 1. Remove a sealing cap [B] per sprinkler pipe [A] (observe internal gasket ring).
Page 110: Additive Sprinkling
Operation *Additive sprinkling 3.07 *Additive sprinkling General The additive sprinkling enables a moistening of the wheels with a separating compound. This prevents that bitumen sticks on tyres when laying blacktops. This is the only way to make a neat and even covering. The emulsion may only be mixed of parting agent concentrate and water according to the indications of the parting agend producer (Observe regulations for environment protection).
