SYSTEMS FOR EVALUATING ROAD SURFACE CONDITIONS

MESSVERFAHREN FUER DEN OBERFLAECHENZUSTAND VON STRASSEN

This report reviews systems for evaluating level road surface conditions used in the mid-sixties. German and foreign systems are discussed, also the comparative measurements of level surfaces undertaken with 8 different measuring systems at Inzell, 1951. Mr. Oswald describes the development of his own telescopic ride clearance measuring system which was tested for the influence of speed of measurement, reproductibility, absolute value, calibration. It was later used to measure and classify the road surfaces of the entire Autobahn network. The dynamic values of the ride clearance systems can be made to correspond to the geometrical values needed in civil engineering in a certain region of the speed of measurement. The measurements of road inclines and declines, of road banking and of the curve band are related to the evaluation of road surfaces discussed. All systems discussed lead to the demand that road surface conditions ought to be improved in such a way as to guarantee a miximum of traffic safety.
