patches, we have removed barriers and enabled designers to select the best option for pavement designs.” “This comprehensive but easy-to-use pavement design tool not only covers full-depth concrete, but also provides design solutions for con- crete overlays and composite pavements,” said Wayne Adaska, P.E., PCA’s director of Pavements. “Further, the tool includes other cement- based materials like roller-compacted concrete, cement-treated base, and full-depth reclamation with cement.” Designers also can reach out for design support, using contact infor- mation found on the website to reach a network of pavement design experts. Using PavementDesigner PavementDesigner guides the user through three basic stages of pave- ment design. The user first selects the project type (parking, street, or intermodal facility). The system then guides the user through project- level details and design of the pavement structure. Each module has help screens and conversions built in to assist the user in entering pavement structure details. After pavement structure information is entered and calculated, the user moves to a summary screen where the pavement design may be reviewed, analyzed, printed, and/or saved. “PavementDesigner presents a unique experience to the user, which logically steps the designer through the pavement design process,” said
Brian Killingsworth, P.E., NRMCA’s executive vice president of Local Paving. “The user experience and functionality of the website were foremost in our minds throughout the development. Couple that with state-of-the-art technical methods and reporting and the user will find the design process to be exceptional.” The portal also includes helpful resources, which are readily available from the sidebar. Users can view a PavementDesigner introductory video; view the platform’s map and methodology visual to see solu- tions and a process flow; and watch a video that shows how to use the portal to design a jointed plain concrete pavement. The resource section also includes details from drawings of various concrete pavement structures, as well as images, descriptions, and web links to other resources and tools designed to assist pavement designers and others gain more insights about specific types and applications for concrete pavements. Additional training and support materials will be added as feedback is received.
