4. Major Milestones For Pavement Management
Implement a New Pavement Management System
Web access
Enhanced data access
Enhanced data reporting & mapping
Comprehensive
Enhanced analytical capability
Training
FY 2016 (5 Major Training Sessions in Austin)
FY 2017 (17 Districts)
FY 2018 (8 Districts)

5. Major Milestones For Pavement Management
Implement Network Level Automated Pavement Data Collection in FY 17
Improved Rut and Cracking Measurement
Collecting data at 0.1 mile interval

6. Pavement Management Process Each Year
July:
July – January:
February:
October - July :
July-August:
Build PMIS database for new fiscal year
Statewide Contract for Automated Data Collection
Begin analysis and reporting
Skid Measurements
Train raters for new fiscal year
Build PMIS database for new fiscal year, some sections the pavement type change, if you have an old concrete pavement that was overlaid by a an Asphalt overlay so they have a change in pavement type or if you have a full reconstruction on a highway that changes the pavement type from a Flexible pavement to CRCP. We also update the Traffic information and the ESAls. Right now we are in the process of rating our pavements and collecting rut and ride information.

7. Automated / Semi-Automated Pavement Data Collection

10. Four Year Pavement Management Plans

11. Objective Pavement Management Plan
Develop a comprehensive and uniform pavement management plan which is roadway specific to the greatest extent possible, and is fiscally constrained.
Generate Pavement Condition Projections based on a financially constrained plan, which can be used to assess the impact of the appropriated funding.
The 4 year plans were required by Rider 55 a legislative requirement. We need to know the expected performance of the planned projects.
The 4-year plan has been managed by the maintenance division and by the director maintenance or operations in the districts.
The bulk of the projects and the funds that have an impact on the performance are CAT1 projects programmed by TP&D
The summary of the projects for every district are sent to CTR and they perform an analysis and provide a prediction of the PMIS scores

12. Objective Pavement Management Plan
Assure maintenance resources are directed towards pavement operations and roadway related work.
Provide a reporting mechanism for District Engineers, Administration and Commission to utilize in briefing elected officials.
Allow districts and regions to appropriately allocate resources through long term planning in order to accomplish the plan.

13. Pavement Management Plan Timeline
Preliminary plans due by May 30th
Plan reviews done by June 15th
Final plans due by July 1st
Draft report by MNT on August 1st
Final report by August 31st
Districts present their plans to a team from TxDOT administration in June. The plans are reviewed and finalized by the end of June.

14. Pavement Management Plan
Year of the project (2019, 2020, 2021, 2022)
Years 2019 & 2020 Project Specific
Year & 2022 Project Specific or place holders.
The 4 year plan is project specific for years 1 & 2. For years 3 & 4 the plan can be project specific or it can be a funding allocation xx amount of $dollars for PM is allocated for a county or a maintenance section. We are trying to push the districts to be project specific for the 4 years. Districts with very good seal coat or chip seal programs have project specific information for 4 years.

15. Pavement Management Plan Information
Highway
County
Roadbed (ML or FR)
Direction (North, South, East, West)
Location (Beginning & Ending Reference Marker and displacement)
Treatment Level
For years 1 and 2 when project specific information is required the highway, county, roadbed, direction, location and treatment levels are needed

16. Routine Maintenance Sealing Cracks Edge Maintenance
Patching/Pothole Repair
Level-up
Strip/Spot seals
Milling
Joint Repair
Isolated Base repair
Concrete Repairs

17. Preventive Maintenance For Flexible Pavements
Seal Coat / Chip Seals
Thin Overlay 2" Thick or Less
Mill and Inlay 2" or less
Hot In-Place Recycling
Micro-surfacing/Slurry Seal

18. Light & Medium Rehabilitation For Flexible Pavements
Light Rehabilitation
Overlay Greater Than 2" Thick But Less Than 4"
Mill and Inlay between 2" to 4“
Medium Rehabilitation
Overlay Between 4" and 6"
Mill and Inlay Greater Than 4" But Less Than 6“
White-topping

19. Heavy Rehabilitation For Flexible Pavements
Overlays Greater than 6“
Mill and Inlays Greater than 6“
Full Reconstruction
Full Depth Reclamation (Pulverization and stabilization) new HMA surface
