Local Road Management Manual 346 which is a more precise method. This rating usually involves measuring some dimension of the item being rated. The definition of what each rating means is found in the words that accompany the item’s condition codes. Where the condition of any item constitutes a hazardous situation at a particular location, the matter should be reported immediately to the relevant authority for urgent attention. 2.2. RATING SEGMENTS Implementation of the ROCOND rating system will require the assessment of segments between consecutive kilometer posts. • There can be many pavement types occurring between each set of kilometer posts, resulting in more than one segment per km. • Only pavement lengths that are greater than or equal to 50m in length are to be surveyed, with the exception of gravel/earth segments, which are rated irrespective of their length. • If there is less than 50m of the same surface type after a kilometer post then this should be added to the previous section. • If the number of lanes changes for more than 100m then this should also be considered a separate link. • If there is a change in surface type less than 50m long, either at a bridge or any other location, this change of surface type is not considered as a separate segment. • If a bridge is longer than or equal to 50m with a surface type different to the rest of the segment then a new segment should be created and rated. • If the surface type on the bridge is concrete then it should be treated as continuously reinforced concrete with no gauging length ratings. • Segments are not split at temporary bridges. Figure 2.1 shows typical examples of road segments.
