The Dynapac CA600 is available in D (smooth drum) and PD (padfoot) versions, of which the CA600D is designed for compacting rock fill. The main range of application for the PD versions is on cohesive material and weathered stone material. All types of base courses and subbase courses can be compacted deeper and the interchangeable drums, D to PD, and vice versa, facilitate even greater variety in the range of application.
