The Willow Grove road project, managed by DELDOT, involved the removal and replacement of the existing concrete roadway in Willow Grove, Delaware. Key aspects of the project included detouring traffic, rubblizing the existing concrete, excavating and preparing the subgrade, and laying a full depth of 10-inch PCC pavement, with a total of 3,600 cubic yards of concrete placed. Due to the absence of a central mix plant nearby, Diamond Materials implemented an innovative solution by offloading mixer trucks into tri-axle dumps for efficient concrete placement. The project, which presented unique challenges due to the nature of concrete replacement, demonstrated Diamond Materials' adaptability and teamwork. James Osborne, a Design Support Engineer at DELDOT, praised Diamond Materials, Century Engineering, and DELDOT specialists for their collaborative effort in successfully completing this complex project.
"The replacement of a concrete roadway presents many challenges due to the product’s life cycle and properties that will allow history to lay dormant and not show the subgrade or existing constraints until work begins. This would be the case with the concrete replacement on Willow Grove Road, and this is also how a company such as Diamond Materials, LLC adapted to the site needs to complete a final product that all parties can appreciate. I would like to extend a thank you to all of Diamond’s site and office employees, Century Engineering inspection staff and the Department’s many specialists for the assistance throughout the project. It takes a team to create, construct and implement a DOT project and Diamond Materials is a team player."
