GENERAL REPORT: DRAINAGE, PERMEABILITY AND FROST

This paper relates to problems experienced with open graded drainage layers and retrofitted edge drains in Ontario. This general report draws attention to a number of other case studies in North America and the UK, which confirm the requirement that all components of the drainage system (under and edge drainage collectors and discharge points) must operate satisfactorily if serviceable drainage is to be achieved throughout the design life. Brief comments are made on two other papers in which methods of predicting or measuring permeability, including the use of a newly developed 300mm vertical permeameter, were presented. Finally, although no papers were submitted, some recent developments and trends on frost aspects are discussed. (A) For the covering abstract see IRRD 890992.
