WATERSPRAY FROM HEAVY GOODS VEHICLES: AN ASSESSMENT OF SOME VEHICLE MODIFICATIONS

The tests described in this report are a continuation of earlier work carried out by the TRRL. A variety of larger vehicle/trailer/container combinations were tested at 80 km/hr on a track drenched by a sprinkler system. Four aspects of mudguard design and various airflow devices were tested. A description is provided of the experimental techniques and equipment used, including spray measurement by laser beam. The effects of vehicle design, speed, and depth of water on the road are discussed. It is concluded that although some reduction in spray was achieved by the mudguards tested, lower speeds in wet weather is the only known, effective and quick solution to the problem. (TRRL)
