Dilapidation

RPS compares conditions of the same roads overtime to measure dilapidation

Due to the high accuracy of our measures and our positioning systems the same location can be precisely compared from one scan to the next. The first stage of comparison is to use laser measures (e.g. rutting and roughness) to automatically generate a quantitative evaluation of the road condition. After this localized surface defects on sealed roads are detected using the collected Photometric data. At any point in time, the assessment can be upgraded to a complete surface defect analysis if required.

For dilapidation surveys, RPS compares conditions of the same roads overtime in accordance with TMR's Road Condition Evaluation Manual for Queensland. Alternatively, other technique can be used if required.
