Pavement Condition Performance Management regulations supports the implementation of the National Highway Performance Program (NHPP) and requires State Departments of Transportation (DOTs) and Metropolitan Planning Organizations (MPOs) to establish pavement condition targets for four performance measures.
|NATIONAL GOAL||PERFORMANCE AREA||PERFORMANCE MEASURE|
|Infrastructure Condition||Pavement Condition||
When do MPOs establish Pavement Condition targets?
States must establish two- and four-year pavement condition performance targets for both the Interstate system and the non-Interstate National Highway System (NHS) every four years. Once the state informs the MPO it has set its performance targets, MPOs have 180 days to either set their own quantifiable four-year targets for the metropolitan planning area or support the state’s established four-year targets.
How are Pavement Condition targets reported?
States report their Pavement Condition targets to the Federal Highway Administration in their Performance Reports. The Jackson MPO reports its Pavement Condition targets every four years to the MS Department of Transportation (MDOT), and evaluates its progress toward achieving established targets every five years in the Metropolitan Transportation Plan.
Pavement Condition target calculations
Regulations require pavement conditions to be assessed based on International Roughness Index (IRI), cracking, rutting (for asphalt pavements) and faulting (for jointed concrete pavements). The table below shows the thresholds for determining whether pavement segments of 0.1 mile are in good, fair, or poor condition. Regulations have also established a minimum pavement condition for the Interstate System of no more than 5% in Poor condition. Highway Performance Monitoring System pavement inventory data is used to calculate good/poor conditions. A segment is considered in good condition if all three criteria are rated as good; it is considered poor if two or more criteria are rated as poor. All other segments are considered fair.
|IRI (inches/mile)||<95||95 – 170||>170|
|Cracking (%)||<5||CRCP: 5 – 10
Jointed: 5 – 15
Asphalt: 5 – 20
|Rutting (inches)||<0.20||0.20 – 0.40||>0.40|
|Faulting (inches)||<0.10||0.10 – 0.15||>0.15|
|Present Serviceability Rating (PSR) (0.0-5.0 value)*||≥4.0||2.0 – 4.0||≤2.0|
|*PSR is a composite of cracking and rutting and may be used only on routes with a posted speed limit < 40mph|
|Performance Measure||2021 Mississippi Baseline||2021 Jackson MPO Baseline|
|% of Interstate Pavement in Good condition||71.2%||72%|
|% of Interstate Pavement in Poor condition||0.7%||0.3%|
|% of Non-Interstate NHS Pavement in Good condition||37.7%||16%|
|% of Non-Interstate NHS Pavement in Poor condition||4.2%||12%|
2022 – 2025 Pavement Condition Targets
