Road Surface Management System

Road Surface Management System

NRPC works with towns in the region to conduct Road Surface Management System (RSMS) projects. RSMS projects assess the physical condition of town-maintained roads and provide the town with a 10-year plan to repair, maintain and rebuild roads using cost effective methods.

NRPC helps the town strategically develop a scenario of how best to spend their paving budget. Often NRPC will help towns develop multiple scenarios to compare strategies, advocate for additional funding, or explore other factors. In the end, these scenarios have the potential to help town officials make data informed decisions to improve their road networks while saving money in the long run. 

NRPC utilizes the New Hampshire Statewide Asset Data Exchange System (SADES) which was developed as a partnership between the University of New Hampshire Technology Transfer Center (UNHT2) and the New Hampshire Department of Transportation. Since 2014, UNHT2 has supported all nine NH regional planning commissions in their efforts to provide Road Surface Management System (RSMS) assessments to their member communities.

RSMS projects have two phases:
1. Road Inventory Assessment
2. Forecasted Repair Scenarios

For the Road Inventory Assessment, NRPC staff conducts a windshield survey of every segment of paved, town-maintained road. In this assessment surface defects such as cracking, rutting, potholes, and more are recorded and pavement width is measured. NRPC staff work with the town to identify what roads pose the most challenges for the town department of public works. At the end of this process a Pavement Condition Index (PCI) value is generated, which summarizes all the surface defects detected in the windshield survey into a 0 -100 score.

To create Forecasted Repair Scenarios, NRPC and town staff use the PCI values to determine what types of repairs are suitable for which roads. With SADES tools they can predict how PCI values will change and forecast costs for different types of road repairs.


While approaches to road maintenance can vary, one guiding principle of the RSMS process is the need to make a practical plan that will save the town money over time. To do this, importance must be given to roads in a variety of conditions, not just roads in the worst shape. By taking advantage of cost-effective pavement preservation techniques, towns can keep their good roads good, and prevent roads that are in good condition from falling into a state that would require expensive reconstruction.
