This Slope Maintenance Manual has drawn extensively on road construction and maintenance experience in south-east and south Asia over the past twenty years. The emphasis is on practical guidelines for the prioritisation and maintenance of existing slopes and retaining walls, particularly those that are undergoing or have undergone severe distress or failure. The Manual does not attempt to repeat topics covered in standard textbooks on the design of highways, retaining walls and cut slopes.
The manual is intended mainly for use in the Provincial Departments of the Ministry of Public Works and Transport (MPWT) by field engineers. The accompanying Slope Maintenance Site Handbook has been written to provide guidance to field supervisors.
