POSSIBLE LOSS OF DIRECTIONAL CONTROL WHEN DRIVING ON SECTIONS OF SANDED, PRIMED SURFACE ON HIGHWAY CURVES

The report investigates possible driver-vehicle behavior when an abrupt change from a high friction sealed pavement to an adjacent section of primed and sanded surface occurs on a road curve. In particular, it examines the possibility of the change in friction properties along the curve producing a potential loss of directional control situation. It is concluded that the change in surface can indirectly lead to skidding. As a consequence, it must be regarded as a hazard which should be indicated by appropriate warning signs.
