Pavement Modeling

Pavement Authority by WithersRavenel uses data and cutting-edge technology to provide detailed lifecycle modeling of your road conditions for decades to come. With our expertise in roadway assessment and lifecycle management, we can adjust our models to show how budget changes or different treatments would affect your roadways in the future.

Our insights give you the information needed to keep your road network in good shape now and in the years to come. Clients use our models to:

  • Advocate for necessary maintenance funding
  • Prioritize which roads to treat, rehabilitate, or reconstruct
  • Set strategic goals based on future insights

With shrinking budgets and increasing stresses on your roads, engineers, planners, and public works professionals have to make tough calls every day. Pavement Authority gives you the tools to make informed decisions for your city’s future needs. No more guesswork or repaving the worst roads first. We give you the information to address your greatest needs before they become a problem.

Why Pavement Authority?

Don’t let your pavement conditions crash due to a lack of maintenance and care. Acquiring funding for necessary repairs is often a challenge, but we provide critical data to help stakeholders make informed decisions. Roadway assessments using both windshield surveys and artificial intelligence combined with lifecycle modeling using cutting-edge technology put you in the driver’s seat to keep your roads in top shape.

Yelm does not have the resources available to adequately rate the condition of its pavement system, nor the ability or expertise to perform a life-cycle analysis. WithersRavenel prepared a concise summary of the City’s street inventory, overall condition of the roadway network, asset value, maintenance needs, and cost summary in an easy to follow format. The Project Manager, Steve Lander, was in continuous communication with the City, providing updates as to when the rating crew would be arriving on site, during the process of obtaining field data, and throughout the report preparation phase. Yelm would recommend WithersRavenel’s services to others. These services were performed exactly as promised, on time, and on budget
