Preserve our assets
Performance Dashboard
Goal: Deliver preventive maintenance for TxDOT’s system and capital assets to protect our investments.
Objectives:
- Maintain and preserve system infrastructure to achieve a state of good repair and avoid asset deterioration.
- Procure, secure, and maintain equipment, technology, and buildings to achieve a state of good repair and prolong life cycle and utilization.
Bridge condition score
Measurement of bridge conditions on Texas roadways. Tracking bridge conditions allows us to forecast performance and determine trends given various funding scenarios for bridge maintenance, repair and replacement.
The Bridge Condition Score indicates the current overall physical health of all bridges in the state. This measure takes into account the average of each vehicular bridge’s condition rating, weighted by the size of the bridge. This measure can range from 50 to 95, with a higher number indicating a healthier bridge inventory.
Bridge Condition Scores apply to four different categories of roads:
- Statewide (All Highway Types)
- National Highway System Interstates
- National Highway System Non-Interstates
- Non-National Highway System
Percentage of lane miles in good or better condition
Measurement of pavement quality on Texas roadways. Tracking pavement quality helps us identify roads in need of repair and plan funding for their maintenance and rehabilitation.
Pavement condition score is a combined index of ride quality and pavement surface distress, adjusted for traffic and speed. The data for ride quality and pavement surface distress is combined to provide an overall score ranging from 1 (worst condition) to 100 (best condition) per lane mile. A score of 70 or above indicates the pavement is in good or better condition.
Percentage of lane miles in good or better condition is the ratio of pavement lane miles on Texas roadways that scored 70 or above to the total lane miles, described in five different categories of roads:
- Statewide (All Highway Types)
- National Highway System Interstates
- National Highway System Non-Interstates
- Non-National Highway System
- Energy Sector
How TxDOT preserves bridge assets
Texas is home to the largest network of vehicular bridges in the country (more than 57,000 structures). TxDOT is responsible for ensuring that these bridges remain in safe condition.
Despite having nearly twice as many structures as any other state in the country, only 1.0% of Texas bridges are currently in "poor" condition, which is the best in the nation. Texas has excelled at reducing the number of "poor" bridges largely due to strategic funding programs that efficiently repair or replace them.
While replacing or rehabilitating bridges in poor condition in the Texas bridge inventory is an important and effective approach to eliminating our worst-performing structures, TxDOT has ramped up efforts to take preventative measures to ensure bridges remain in acceptable condition for longer periods of time.
As Texas' network of bridges continues to grow and our existing infrastructure ages, advanced programming becomes more critical. TxDOT is working to proactively manage its bridges through data-informed asset management techniques that maintain bridges in a state of good repair for longer periods of time.
Pavement management plan: helping TxDOT maintain roads
Each year, all 25 of our districts develop a comprehensive Four-Year Pavement Management Plan. The plan covers the maintenance and rehabilitation work planned for pavements in the district.
The Four-Year Plan allows districts to more effectively allocate finite resources through long-term planning to meet pavement-condition objectives. Through the plan, districts can identify their highest priority projects and work based on available funding. From the planned projects, we can better predict future pavement conditions for individual districts and the state as a whole.
