Local Road Management Manual 352 2.3.1.2. Rigid Pavements For rigid pavement roads, regardless of the number of lanes, only a SINGLE lane 50m gauging length is selected. (Refer in section 3.2.). This gauging length survey is usually assessed on the side of the road with increasing chainage but can be assessed on the side of the road with decreasing chainage if that side of the road is in an inferior condition, possibly due to heavier traffic. The three distress types of joint faulting, joint spalling and joint sealant are rated over this length. Figure 2.8 Two Lane Rigid Pavement Road 2.4. LOCATION IN THE ROAD SYSTEM The location of start and end points for each rating segment is described by reference to the nearest kilometer post. As shown in the sample preprinted condition assessment form in section 4, the distance of the start and end point of the survey is clearly marked at the top of the form. In situations where there is less than 1 km of continuous pavement with the same surface type between two kilometer posts there may be more than one form to complete (one for each pavement length that is greater than 50m in length). In certain cases where there are no kilometer posts, the start and end points of each kilometer will have to be determined from Location
