Quality Control of Asphalt Density with the PaveScan MDM

PaveScan Mix Design Module (MDM) immediately alerts paving contractors if there is a change in the mix.

PaveScan MDM detects even minute changes in aggregate, mix and moisture. Comparing daily samples to authorized mix designs reveals any deviations and allows any issues to be addressed before the mix is put in the field. Users can properly expose faults with a 5-minute lab test, eliminating the need for silo dumps or other costly remedies.

PaveScan MDM also transforms the PaveScan RDM system into a new Quality Control (QC) tool for determining asphalt density. PaveScan MDM establishes a relationship between the mix’s dielectric value and the percentage of voids contained.

PaveScan RDM uses this correlation to reveal correct density fluctuation inside the asphalt mat. Bridge decking and longitudinal joints may now be rolled to specification in real-time thanks to this level of process control.

Powerful New QC Tool for the Lab and the Paving Site

PaveScan technologies used together can help prevent early road failures such as raveling, cracking and degradation along poorly compacted joints.

Improve Quality – Save Time and Money

Reducing maintenance expenses and repaving cycles may be achieved by improving the durability and lifetime of the roadways. If delays or paving train stops cause compaction issues, quality control managers can now repair pavement faults before it is too late, saving time and money in the field. PaveScan technology helps users avoid costly penalties, rip-ups and repaving.

Improve Safety

PaveScan MDM and RDM provide paving contractors with a comprehensive and accurate picture of pavement quality without the cost, danger or faults associated with spot coring. More significantly, by decreasing the need to core, fewer employees are exposed to work zone hazards.

Towards Coreless Compaction

Coring is a harmful process that damages the road surface’s integrity. Reduced or completely eliminated core requirements result in lower costs, improved safety and fewer potholes per mile.
