About the Project
The City of Fort Wayne, Indiana selected APTech as a subcontractor to evaluate the condition of a 1.3-mile segment of East State Boulevard and develop rehabilitation design recommendations.
Our work for this project included:
Collecting and reviewing records regarding the existing pavement structure and the traffic loadings applied to the pavement.
Performing a Pavement Condition Index survey with 100 percent coverage to objectively rate the condition of the pavement.
Mapping the locations, severity levels, and amounts of pavement distresses to identify appropriate treatments and estimate quantities of treatments.
Conducting falling weight deflectometer (FWD) testing to assess the pavement's structural condition.
Developing coring and subsurface boring plans and dynamic cone penetrometer testing plans, and evaluating the test results to determine layer thicknesses, subsurface conditions, and subgrade support conditions.
Analyzing historical traffic data and developing projected traffic growth rates for pavement design development.
Quantifying the structural properties of the pavement and determining the pavement's load-carrying capacity through FWD backcalculation analysis.
Developing feasible rehabilitation design options and performing a life-cycle cost analysis to identify the most cost-effective strategy.
Summarized this information and presented a recommended rehabilitation design in a project report.
The results of the evaluation indicated that concrete pavement restoration in the form of slab replacements, partial- and full-depth portland cement concrete repairs, diamond grinding, and joint resealing, was the preferred rehabilitation strategy. The recommendation was accepted, and plans were made to implement this long-term, cost-effective approach.
