Understanding Return On Investment (ROI) is critical to designing a treatment plan that maximizes your profits and minimizes the possibility of a loss.
A conventional method of pavement management which uses limited budgets to address the most deteriorated roads first. Miles of good roads go untreated each year, accelerating the decline of the overall network.
Many agencies are identifying pavement management strategies that use limited resources more efficiently, and designing treatment plans that reallocate budgets to make incremental network gains (instead of losses) each year. Use our Remaining Service Life tool to find out if your treatment plan is adding or subtracting life from your network. Learn more about basic Network Optimization here.
Used to measure the total length and lane count of a given road. Lane-Miles are calculated by multiplying centerline mileage by the number of lanes.
Example: A four-mile stretch of a six-lane highway has 24 lane-miles.
Lane-mile-years are the measurable loss or addition of pavement life. A 300 lane-mile network will lose 300 lane-mile-years each year, unless treatments are added to increase remaining service life. A treatment with a 10 year life extension on 5 lane-miles of pavement will add 50 lane-mile-years to the network. See A Quick Check of Your Highway Network Health for additional information.
