7.2.4 Rolling

Rolling is usually undertaken by a multi-tyred roller (Figure 7.1). This assists in embedment of aggregate into the binder and reorientation of aggregate for maximum surface contact and interlock. Rubber‑coated vibrating drum rollers may also be used. Steel drum rollers should be avoided as excessive use may cause breakdown of aggregate.
