Pavement Management

We conduct pavement condition assessment and long-term performance predictions so that we can advise you on the most effective preventive and corrective maintenance strategies to extend the life of your pavement network as much as possible under any budget conditions.

Proper pavement management, including periodic condition assessments, updated performance predictions, and the use of proper maintenance strategies, is vital to the long-term success of any pavement asset. Our engineering staff has developed nationwide experience in managing pavement and continue to push the envelope in research, ensuring every dollar you spend on your pavement projects stretch farther and delivers greater value.

Services include:

  • Road network inspection
  • Pavement management plan development
  • Independent validation and verification
  • Quality control and quality assurance
  • Pavement performance research

Virginia DOT Pavement Data and Evaluation Services

The Virginia DOT has been able to trust the quality of its pavement condition data for the last two decades, thanks to independent data verification and quality assurance services provided by QES.

Key Services:

  • Data quality management
  • Independent verification & validation (IV & V)
  • Quality assurance
  • Pavement management

For over 20 years, QES has provided state-of-the-art pavement data quality assurance (QA) services to an independent data collection vendor and the Virginia DOT. In 2000, we developed a quality monitoring plan for the Virginia DOT and established statistical control limits for each data element. Our work continues and QES performs annual data QA and independent verification and validation for data collected on 28,000 miles of interstate, primary, and secondary routes in the state of Virginia, including QA on pavement roughness, rutting, and automated distress data pulled from digital images. This project is a massive annual undertaking, but we work with the Virginia DOT and the data collection vendor to ensure that data is accurate at every phase of the project. Our input has helped create an accurate pavement management system for the Virginia pavement network and has also led to updates for the Virginia Pavement Distress Identification Manual, resulting in more robust distress criteria for the state.

San Francisco Bay Area Metropolitan Transportation Commission (MTC) PTAP-14 Through PTAP-21

The City of Milpitas, CA was able to make fully informed decisions to maintain their pavement network when they used QES services to design a number of budget options for repairing their roads.

Key Services:

  • Pavement management
  • Manual distress surveys
  • Modification of decision trees and unit cost
QES provided pavement management system (PMS) services to the San Francisco Bay Area MTC through the P-TAP program for eight consecutive years. Over these years, we have updated the StreetSaver PMS systems of 34 separate cities. Project details include manual pavement distress surveys, updates to the StreetSaver system including decision trees and cost tables, and generating various budget option reports. Each city has specific budgetary limitations, and the development of long-term pavement management plans requires individualized solutions, tailor-made to suit each city’s needs. Each of these projects were completed on-time and within budget, ultimately resulting in cost-efficient PMSs that optimized long-term pavement performance and improved local road networks

2017 Seattle DOT Arterial Pavement Condition Rating

The City of Seattle was able to trust the information gathered for its pavement management system and use it to optimize its pavement repair budget thanks to the data collection and QA services of QES.

Key Services:

  • Automated pavement distress data collection
  • StreetSaver distress ratings
  • Pavement management update

The City of Seattle sought to update their pavement management system (PMS) for their arterial pavement network. QES worked with a data collection vendor to conduct a pavement condition survey of 1,547 lane-miles of arterial pavements using the PathRunner system. We analyzed the images using automated crack detection and classification software and manually verified and supplemented the automated results, using robust quality control and assurance checks at every phase of the project. QES interfaced with Seattle’s StreetSaver PMS database to create a foundation for an in-depth PMS plan that would allow the city to make the best and most economical decisions for where to treat their pavement network and which rehabilitation methods to use.

Erie Airport Master Plan And Airport Layout Plan Update

The Erie International Airport was able to effectively plan two decades into the future because of QES’s long-term pavement condition forecasts.

Key Services:

  • Pavement evaluation
  • Pavement inventory mapping
  • Analysis and cost estimating using PAVER

In 2017, the Erie International Airport needed an accurate pavement condition assessment to serve as a foundation for the development of a new Master Plan. QES collected field distress ratings and used them to determine pavement condition values for two runways, which we then extrapolated to create both five and 20-year capital improvement plans. Our work ensured that the Erie International Airport was able to craft a Master Plan which accounted for the long-term condition of their runway pavement and allowed them to prepare for future rehabilitation efforts.
