Road Assessment for Councils

Network collection using PaveScout technology is all about quality combined with simplicity

RPS can provide a comprehensive assessment of your entire road network using our PaveScout platform to collect surface, subsurface and environmental image data.

Once collected this data is processed to produce rutting, roughness, texture depth and environmental camera images automatically aligned to your existing maps either based on chainage, sections or geospatially.

During network collection, the same data is collected as for project level work, meaning that detailed "project" based degradation measures are always available if required. Post collection, the data is processed to produce rutting, roughness, texture depth and environmental camera images. This also includes all correction of GPS positions and the automatic filtering of roughness as often required for suburban areas. The end result is this data can be provided at a very reasonable cost and time. The reduction in the manual "hands on" filtering and qualification of data means that our data is also more repeatable.

The next stage of delivery is crack mapping. The detailed photometric based surface imaging system allows detection of cracks that would normally go undetected by environmental cameras, which rely on natural light or windscreen surveys. The detection of cracking early is very important for road pavement life. When a crack is small, there is normally no associated pavement base damage, and thus crack sealing can be applied with the expectation of maintaining or extending the pavement life. As the crack gets bigger or starts to exhibit pumping of fines, then the time has passed for crack sealing, so instead a resurfacing or more correctly a resurfacing with localized base correction would be required. As can be seen, identifying issues early is very important and will result in large savings in the future when considering total pavement life.

A cheap survey is almost never cheap in the long run.

Finally when it comes to performing rehabilitation, having this historical data on hand allows a more complete picture of the state of the road and the rate of change in the road with time. Rutting, roughness and cracking maps can be compared over time, to a new level of accuracy when combined with the RoadLock technology to produce a more complete assessment of the rate of degradation of the different sections of the pavement.

Unsealed Road Assessments

For unsealed roads, while the Photometric system can be used, this high resolution data is often too detailed. Instead, RPS utilizes the laser and environmental cameras, in combination with our high precision positioning system to determine road condition. In this case the Photometric system automatically rolls up to prevent damage to the lighting system.

Due to the high intensity and accurate positioning of the laser profiling system, RPS is able to produce an accurate profile of a dirt road. When combined with the GPS/IMU position, it is possible to determine standard measure such as rutting and roughness, but also extended measures related to cross-fall (which related to poor drainage) and texture measures. Finally the environmental cameras provide video evidence of road state, as required in many road maintenance contracts.
