Pavement Management Plan

Study Objectives

• Understanding of the current roadway condition
• Development of a pavement management

system

• Performing a network-level pavement condition

survey

• Applicable software to identify future M&R

needs.

• Future maintenance costs

Good Condition Poor Condition

Pavement Management Plan

Study Approach

• Implemented the Paver™ system roadway

pavement network.

• Pavement Condition Index (PCI) Survey

Performed a network-level field condition survey and established a PCI

• f the Township’s roadway pavements.
• Roadway Pavement M&R Budget Analyses

Performed five-year budget analyses of multiple scenarios using Paver™ to determine future needs of alternative scenario.

Pavement Management Plan

Benefits of a Pavement Management Program

• Quantify Maintenance & Rehabilitation (M&R) budget
• Evaluate different budget scenarios
• Analyzing cost effectiveness of alternative strategies.
• Establish an objective funding program
• Establish Central repository for inventory data.
• Schedule timely M&R activities.
