Our Work

Using the data collected in the PCS, we created a working pavement lifecycle model that supported the City’s infrastructure investment planning processes. The model included multiple budget scenarios and predefined treatment options.

Pavement Condition, Survey, Lifecycle Model, & Managed Services

City of Yelm, WA

The pavement condition survey (PCS) conducted by our team assessed the overall condition of City maintained roadway segments for the project, which totaled 42 centerline miles of road. To carry out the survey, our staff rode each street segment and followed a nationally recognized distress identification manual to determine the severity and extent of seven distresses used to determine the PCI of each segment and the entire roadway network. After completion of the survey, our experts provided a report that described methodologies, procedures, and recommendations that were explained at an online deliverables meeting.

Using the data collected in the PCS, we created a working pavement lifecycle model that supported the City’s infrastructure investment planning processes. The model included multiple budget scenarios and predefined treatment options. Treatment options featured preservation-prevent (rejuvenators), crack seal, patching, preservation-correct (micro-surfacing, slurry seal etc), rehabilitation, and Full Depth Reclamation (FDR).

After the model was delivered, our team provided Yelm with managed services for the length of the PCS contract and then yearly thereafter. These services allow for the model to be updated as infrastructure is added or repaired throughout the year. We also provide support for any questions regarding the existing model or budget simulations and results.

Lifecycle Modeling

Gibson County, IN

Gibson County came to us requesting help on improving its roadways while not exceeding a fixed budget. Our Asset Management team worked closely with the County to develop a 40-year asset lifecycle model based on their current pavement program. We were able to show a continuous decline in infrastructure if their roadways were not addressed properly. However, there were concerns that repairs and improvements would exceed the County’s budget.

With in-house pavement expert recommendations, we were able to present Gibson County with a solution that required no additional financial resources because there were different ways to manage their infrastructure and reach their goals. Our team presented various models and projections that allowed the County to save money and extend the performance and life of its road network.

Our experts combined the County’s pavement condition survey data with their pavement management treatment decision tree to trigger the correct pavement treatments for County roads

Pavement Management & Lifecycle Models

Carver County, MN

Located just southwest of Minneapolis—St. Paul, Carver County is a mostly rural part of Minnesota with a population of about 103,000. We assisted the county with the development of two pavement lifecycle models.


For the first model, our experts combined the County’s pavement condition survey data with their pavement management treatment decision tree to trigger the correct pavement treatments for County roads. The results of the initial modeling project were then used to create a second model, which notifies the County when striping and painting should be applied to street segments.

Pavement Management & Lifecycle Models

Town of Ayer, MA

The Town of Ayer, Massachusetts, recently increased their pavement management budget to cover the cost of additional roadway treatments. Following budget approval, the Town reached out to us to verify their current pavement management strategy is the most effective use of the funds.


Our team helped the Town implement Capital Predictor and use it to develop a pavement life cycle model. The model used four sources of data: the Town’s GIS data, prioritization rules (condition assessment model criteria), Pavement Condition Index (PCI) rating data, and a decision model. We established the decision model through workshop meetings with the Town’s pavement system managers.


Multiple budget scenarios, including the Town’s newly approved budget, were entered into the life cycle model. After reviewing the results, we confirmed the new annual budget is the most efficient use of funds for improving and maintaining the Ayer road system.


Now that Capital Predictor has validated the budget, the Town can focus on using the pavement life cycle model to schedule the recommended treatments to improve the overall condition of their roads in both the near and long term.

The pavement management services keep the City’s model up to date by tracking pavement treatments the City has applied, unit costs changes, and other factors.

Pavement Condition Survey, Management & Lifecycle Model

Rock Hill, SC

Located just across the border from Charlotte, Rock Hill is a thriving suburb of the Queen City with a population of around 75,000. We completed a pavement condition survey (PCS) for the City, and then established a pavement management work plan by incorporating the PCS results into a pavement lifecycle model.


Our team also provides the City with pavement management services. The services keep the City’s model up to date by tracking pavement treatments the City has applied, unit costs changes, and other factors.

Pavement Management & Lifecycle Models

Lawrence, KS

The City of Lawrence, KS, has a population of about 97,000 and is home to the University of Kansas. Our team helped the City to build a pavement lifecycle model. The pavement model was designed to sync with an existing water lifecycle model, so the City could prioritize and plan for both upcoming pavement and water projects. The coordination of asset management across infrastructure platforms will allow the City to recognize time, material, and cost savings.

Pavement Condition Survey and Street Resurfacing

City of Lexington, NC
Project Completion Date – Nov 16, 2020

Pavement Authority by WithersRavenel provided a visual pavement condition survey (PCS) for the City using the Long-Term Pavement Performance (LTPP) definitions recommended by the Federal Highway Administration (FHWA) on approximately 125 centerline miles of City-maintained streets. The firm used this method, which involves recording severity and extent for all distresses, because it enables better decision-making from more granular data.

To ensure quality, both raters communicate what they have observed. If they are not in agreement, they re-rate the segment until they reach an agreement.

At the conclusion of the PCS, Pavement Authority used Capital Predictor™ by Dude Solutions™ for the predictive modeling of the City’s pavement. Pavement Authority presented the finding of the PCS and software to Council. It is anticipated the City will incorporate other assets into the software at a later date.

Pavement Authority is currently assisting the City with the FY21 Resurfacing Contact and will be assisting with the construction inspection.

Pavement Condition Survey and Street Improvements

Town of Cary, NC
Project Completion Date – May 28, 2021

Pavement Authority by WithersRavenel performed a visual pavement condition survey (Task 1) for the Town using a methodology and approach consistent with the method developed by NC State University’s Institute for Transportation Research and Education (ITRE) on approximately 522 centerline miles of Town-maintained streets.

At the conclusion of the PCS, Pavement Authority provided the Town with a report, street listings, a GIS geodatabase, and maps that will be published on the Town’s website.

Pavement Authority assisted the Town in furthering the efforts of the Neighborhood Approach, which was developed in 2018, by creating new paving groups for new subdivision streets and selecting the FY22 Street Improvement Project street segments that are included in each of the paving groups.

As part of this contract, Pavement Authority will also be providing Task 2 – Contract Documents and Task 3 – Construction Inspection.

Pavement Condition Survey

City of High Point, NC
Project Completion Date – May 18, 2021

Pavement Authority by WithersRavenel performed a comprehensive pavement evaluation in 2018 on approximately 450 centerline miles of City-maintained streets, resulting in a final product that City staff uses to plan and forecast future projects and budget requests.

In 2018, the PAVER Pavement Management Software was used to calculate the Pavement Condition Index (PCI) for each roadway segment, determine maintenance needs, and estimate costs.

In January 2021, Pavement Authority was selected again to conduct a LTPP pavement condition survey for the roadway network. A report, street listing, and GIS geodatabase were the project deliverables.

After the PCS, the City contracted Pavement Authority to implement the Capital Predictor™ pavement management software by Brightly. The City’s goal is to be able to tell the roadway network story to Council through the predictive modeling. It is anticipated that the City will incorporate stormwater into the Capital Predictor software.
