Perform field data collection, including deflection measurements, coring, sampling, and testing on 57 acres of container yard at Port Elizabeth in Elizabeth, NJ.

QES' responsibilities for the Port Elizabeth project included coring; deflection testing using a Falling Weight Deflectometer (FWD); subgrade evaluation using a Dynamic Cone Penetrometer (DCP); material sampling; and laboratory analysis of existing asphalt pavement, subbase, and subgrade materials. From the analysis, information was developed as the basis for the re-design of the facility pavement. All work was combined into a database and included in the pavement analysis report for the project.

QES recommended various rehabilitation strategies for different areas of the port facility. Field investigation revealed the presence of extensive asphalt pavement stripping in much of the area. As a result, proposed overlay designs in many areas were revised to remove defective asphalt pavement. A new pavement system consisting of both asphalt and concrete sections was developed utilizing state-of-the-art techniques. Full depth asphalt pavement sections incorporated polymer modified asphalt and a fatigue resistant base layer to help resist high loading applications. QES also provided quality assurance monitoring of pavement construction to assure the work complied with project specifications. This included periodic monitoring of placement as well as sampling and testing of materials.
