Local Road Management Manual 344 1. Introduction This manual has been adopted from the ROCOND 90 manual of the Roads and Traffic Authority of New South Wales, Australia. The methodology was first introduced in 1980, and in 1987 the manual was revised and published as ROCOND 87. The most recent NSW edition of the Road Condition Manual “ROCOND 90” updates the earlier publication “ROCOND 87” and has been specifically produced for rural roads. DPWH has made changes to the ROCOND methodology to adapt to the Philippine road conditions and DPWH needs. This publication is a manual for “condition reporting”. Condition reports may be used to: • Measure and record condition throughout the road system; • Describe the condition of the road at the time of rating; • Provide a sequence of recorded condition that can be analyzed to indicate performance trends; • Provide condition data for pavement related items for utilization in a Pavement Management System (PMS); and • Provide condition information on which a Routine Maintenance Management System (RMMS) budget can be based. All these uses will ultimately mean better programming of maintenance work and better choice of maintenance treatments. Measurement of condition can follow one of two formats. Some items are rated on a scale of 1 to 5 utilizing condition descriptions with some simple dimensions. Other items are rated by the severity of distress and extent of distress exhibited. Three severity levels are used and extent is measured in terms of the percentage of area affected by the particular distress. Roads are inspected and condition reported for defined segments that are of same surface type and between 50m and 1 km in length (generally between two consecutive kilometer posts). Gravel segments
