Road rollers – collision avoidance system
Tarmac Group > Ettingshall, Wolverhampton > 01902 382855
Tarmac set out to find a technical solution
when an experienced operative, working in
the group’s Dubai contracting operation,
was killed after stepping into the path of
a reversing 17-tonne roller. A meeting was
arranged with the roller manufacturers and
the suppliers of collision avoidance systems
and a challenge set to come up with a system
that protected an area as wide as the roller
and five metres fore and aft.

The solution lay with the Vehicle Collision
Avoidance System (VCAS) which uses
ultrasonic sensors mounted on the front and
rear of the roller. If a person or object comes
within five metres, an audible warning is given to the driver. At three metres, the roller is
brought automatically to a halt.

The £4,500 system has now been retro-fitted to the entire Tarmac fleet of 150 rollers in the UK and United
Arab Emirates. It is also available commercially.

Tarmac Northern North Area (Concrete & Mortar) has devised a simple and ergonomically
efficient system to eliminate the entrapment risk during truck mixer drum maintenance.
At such times, removal of residue concrete causes the balance of the drum to change, giving the drum the
potential to turn. Traditionally, to immobilise the drum, wooden chocks are wedged underneath either
side. However, the chocks are cumbersome and awkward to handle. Availability is not always ideal!
Tarmac’s system comprises of two flat steel bars, which are fitted and bolted in position either side of the
bell end of the drum. The bolts are attached to the drum and vehicle chassis.
