|A number of measures have been introduced at this quarry to improve the sampling process.
Drivers enter an area segregated from site traffic to avoid congestion. They then exit the vehicle to meet the technician, who closes traffic barriers.
A robotic sampling arm is used to obtain samples of asphalt and aggregates. This removes the need to enter the vehicle eliminating working at height issues. Samples are transferred to the preparation building via a chute which removes manual handling issues.
These measures have removed contact with hot asphalt, working at height and manual handling issues. There is improved access and egress which hasn’t affected traffic flow.
