 The most popular Asphalt Roller Compactor worldwide is robust, reliable and the industry standard.
The Roller Compaction is considered to be the method of laboratory specimen compaction that results in slabs of asphastic 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 Roller Compactor CRT-–RC2S is pneumatically powered and controlled by a 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). 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. A vibration option is available to fully simulate on-site vibratory rollers. See what CRT–RC2S asphalt compaction configurations Cooper suggests.
Key Uses: - Preparation of homogeneous asphalt slabs
- Wheel tracking tests
- Sawing into beams for bending tests
- Coring to produce specimens for indirect tensile and axial tests
Standards: Key Features:- Steel wheeled roller segments
- Solid machine frame
- Model for compaction of 305x400 mm and 305x305 mm slabs
- Roller compactor moulds will fit Copper Technology Wheel trackers so that compacted slabs can be wheel-–tracked without de–moulding
- Maximum compaction load of 30 kN per 305 mm roll width (equivalent to largest on-–site static rollers)
- Speed control
- User friendly HMI for operator selection of number of passes and compaction levels (up to 6). The operator can also save up to 3 compaction routines.
- Vibrating roller option with adjustable frequency to fully simulate on–site vibratory rollers
- Safety enclosure with interlocked doors to prevent unguarded operation
- Slabs can be used as wheel–tracking specimens or sawn into beam fatigue specimens
