PAVEMENT MANAGEMENT
Pavement Management is the practice of planning pavement maintenance to maximize the value of the roadway network.
Enables you to perform the Right Repair at the Right Time on the Right Road!
What is Pavement Management?

• Keep good roads good while performing rehabilitation where necessary.
• Top of curve treatments are less expensive and less intrusive.

NETWORK INVENTORY
Roadway Network
• Accepted vs Private vs. State Roadways
• Accepted Roadways are streets that are designed to Town standards and accepted by Town Meeting. They are maintained by the Department of Public Works
• Private ways are streets that are owned and maintained by the abutting property owners.
• State Roadways are streets that are under the jurisdiction of and maintained by state agencies including MassDOT and Mass DCR

DATA COLLECTION
• Completed using Machine-Learning Technology
• Provides photographs every 10’ along the roadway network
• Non-Biased
• Extremely cost-effective

ANALYSIS & REPORTING
• Excellent• No distresses are observed on the sidewalk. Typically
new segment and/or very well maintained
• Good• No distresses identified up to minor surface
blemishes and deterioration observed on sidewalk.
• Fair• Distresses start to develop, but provide minimal to
no impedance
• Poor• Distresses and obstructions are actively found,
proving the sidewalk to be unsafe in certain areas.
• Replace• Major signs of failure that make sections of the
sidewalk potentially hazardous for public use (60% to 100% of sidewalk requires repair).

Overview
An Asset Management Platform is not meant to be a stagnant document, but rather a living, breathing document.
Consistently updating the information is imperative to minimize costs of continually re-assessing infrastructure.
