Multi-purpose Roller Compactor

Prudct code:CRT-RCMP

Multi-purpose Roller Compactor

The Roller Compactor is robust, reliable and can prepare slabs for different tests in full compliance with international standards

The Roller Compactor is considered to be the method of laboratory specimen compaction that results in slabs of asphaltic paving materials with properties that most closely simulate those of materials in the highway. Slabs can be compacted to target mixture densities using loads that are equivalent to those of full-scale compaction equipment.
The CRT-RCMP and CRT-RCMPV are pneumatically powered and controlled by a programmable logic controller (PLC) connected to an HMI which the operator can use to select the number of passes and compaction load levels. Although the primary function is to produce slabs for wheel tracking tests, the slabs can be sawn into beams or cored to provide specimens for a variety of other tests. Users have compacted hot asphaltic materials over stress absorbing membrane interlayers (SAMIs) on a base of cracked concrete in order to assess the effectiveness of the SAMI by using shear or bending tests.


Standards

  • EN 12697-33 Steel roller
  • Key Features

  • Steel wheeled roller segments
  • Solid machine frame
  • Model for compaction of 305 x 305mm and 500 x 180mm slabs
  • Roller compactor moulds will fit Cooper Technology Wheel trackers so that compacted slabs can be wheel-tracked without de-moulding
  • Maximum compaction load of 30kN per 305mm roll width, or 180mm width (equivalent to largest on-site static rollers)
  • Speed control
  • Fully programmable logic controller (PLC) connected to an HMI (Human Machine Interface) which the operator can use to select the number of passes and compaction load levels (up to 6)
  • Vibrating roller option with adjustable frequency to simulate on-site vibratory rollers
  • Safety enclosure with interlocked doors to prevent unguarded operation
  • Slabs can be used as wheel-tracking specimens, cored to make indirect tensile test specimens or sawn into beam fatigue specimens
  • A vibrating roller is incorporated into the CRT-RCMPV model. This reduces the compactive effort required
  • CE marked

  • Key Uses

    Preparation of homogeneous asphalt slabs:
