DETERMINATION OF A BASIS FOR EVALUATING RUT DEPTHS

项目名称：	DETERMINATION OF A BASIS FOR EVALUATING RUT DEPTHS
摘要：	STATISTICS ON RUTS TO BE FOUND ON FEDERAL MAIN ROADS ARE TO BE DETERMINED, AND AIDS TO THEIR EVALUATION WITH RESPECT TO TRAFFIC SAFETY AND COMFORT ARE TO BE WORKED OUT. THE OBJECT IS TO LAY DOWN CRITERIA FOR DECIDING WHEN RECONSTRUCTION OF SURFACINGS IS NECESSARY BECAUSE OF THE RUTS. THE FOLLOWING WORK IS PLANNED: TESTING OF A PROCEDURE WHICH CAN BE USED ON A WIDE SCALE FOR MEASURING THE RUT DEPTHS; DETERMINATION OF RUT DEPTHS AND SHAPES ON ROADS WITH DIFFERENT STRUCTURE, AND DIFFERENT GRADIENTS AND TRAFFIC LOADS; OBSERVATION OF VEHICLE HANDLING ON SECTIONS HAVING TYPICAL RUTS; CARRYING OUT OF DRIVING TESTS TO DETERMINE HOW THE RUTS ACT AS A RAIL WHEN WHEELS ARE CAUGHT IN THEM, AND THE EFFECT OF THIS ACTION ON LANE CHANGING; DRAWING UP OF CRITERIA FOR EVALUATING RUT DEPTHS.
