Real-time stiffness readings available via new Atlas Copco system

Atlas Copco’s intelligent and simple-to-use compaction system gives contractors real-time material stiffness readings to ensure superior soil and asphalt compaction. It maximises operator productivity, saving contractors significant time and money. Its touch screen capability makes the system user friendly and convenient.

Atlas Copco featured its Dyn@Lyzer intelligent compaction system on the CC6200 asphalt roller at World of Asphalt in Nashville, Tennessee.

Dyn@Lyzer uses a global navigation satellite system to track the number of completed passes and the precise position of the roller at all times. The unit’s drum-mounted accelerometer measures the surface’s relative material stiffness, and uses Evib readings to give operators immediate material stiffness results from within the cab and help minimise the number of passes.

When using Dyn@Lyzer on asphalt the system uses two temperature sensors, one at each end of the roller, to register the surface temperature of the asphalt, giving operators consistent, relative stiffness readings. In addition, Atlas Copco’s intelligent compaction system helps contractors detect any loose materials so they can perform additional passes to reach the right compaction. This minimizes the risk of production related quality defects, which are time consuming and costly to remediate.

Contractors can use the intuitive system on a tablet to set project parameters and view compaction data. Once they achieve the optimal level of compaction, the program alerts the operator, so he or she can stop and reduce the risk of over compaction, which can affect the integrity of the material and damage the roller. The data storage also means contractors have
