RR272 - Load security investigation
The Dynamics and Refinement Department at MIRA has undertaken a
series of tests for Tarmac to assess the stability of a variety of
payloads on an articulated vehicle during cornering and
All tests were carried out on the MIRA Proving Ground. For the
cornering tests, measurements were made of lateral acceleration,
semi-trailer roll angle and vehicle speed. For the braking tests,
measurements were made of longitudinal acceleration levels and
vehicle speed. Payload behaviour during all tests was recorded
using a video camera mounted to the semi-trailer.
A total of eleven different payloads were tested. These payloads
covered a wide cross section of Tarmac Concrete Products' range
and a number of different restraint techniques currently in common
