MODEL TESTS ON THE RUN-OFF OF RAIN WATER ON STAGGERED TWISTING SECTIONS OF ROAD

项目名称：	MODEL TESTS ON THE RUN-OFF OF RAIN WATER ON STAGGERED TWISTING SECTIONS OF ROAD
摘要：	A STUDY IS TO BE MADE TO SEE WHETHER BY TOTAL OR SEMI STAGGERING OF TWISTING SECTIONS OF ROAD ON INDIVIDUAL LANES THE RUN-OFF OF SURFACE WATER ON TWISTING SECTIONS WITH FLAT GRADIENTS CAN BE IMPROVED. THE DANISH ROAD AUTHORITIES HAVE PROPOSED TWO METHODS FOR THE DESIGN OF FLAT TWISTING SECTIONS, WHICH ARE BASED ON STAGGERED TWISTING OF THE INDIVIDUAL LANES. THESE PROPOSALS HAVE THE ADVANTAGE THAT THE SURFACING CAN BE LAID WITH CONVENTIONAL ROAD FINISHERS BETTER THAN IF THE TWISTING SECTIONS ARE INCLINED. THE RECOMMENDED DESIGNS ARE TO BE CHECKED BY MODEL TESTS ON EQUIPMENT AT THE UNIVERSITY OF DARMSTADT.
