INTERNATIONAL ROAD MAINTENANCE HANDBOOK. (PIARC) VOLS 1-4. VOL 1: MAINTENANCE OF ROADSIDE AREAS AND DRAINAGE. VOL 2: MAINTENANCE OF UNPAVED ROADS. VOL 3: MAINTENANCE OF PAVED ROADS. VOL 4: MAINTENANCE OF STRUCTURES AND TRAFFIC CONTROL DEVICES

The pocket-sized Handbook is aimed at those responsible for the maintenance of bituminous or unpaved roads in tropical or moderate climates. It is in four volumes: I, Maintenance of roadside areas and drainage; II, Maintenance of unpaved roads; III, Maintenance of paved roads; and IV, Maintenance of structures and traffic control devices. Volume I also contains a list of terms and a general index for all volumes. General methods are proposed for each activity (with some exceptions) under the headings: The task; Effects; Resources; and Maintenance method. Where appropriate, options are considered for carrying out the work by heavy equipment, tractor based methods or labour based methods. Operations are grouped into routine or periodic. Routine operations are normally small scale or simple and are carried out once or more per year. Periodic operations are normally large scale, requiring specialist skills and resources, and are carried out after a number of years. Emergency work is dealt with as the need arises.
