NEW ASPHALT MIX DESIGN SYSTEM FOR OKLAHOMA DEPARTMENT OF TRANSPORTATION (FHWA-OK-13-03 2238)

Abstract

Oklahoma Department of Transportation (ODOT) has been using the Superpave mix design software for several years. The original Superpave mix design software was built around Fox Database and did not meet ODOT requirements. The software currently being used by ODOT is implemented using two Microsoft Excel® files to create asphalt mix designs and is customized for ODOT use. However, the implementation is inefficient and cumbersome to maintain. The aim of this project is to develop a Microsoft Visual Basic based Asphalt Mix Design Software that is efficient and easy to use. Further, all the pertinent data is stored in a SQL database with strict access security. This design enables users to securely access the mix design data over the internet while enabling ODOT personnel to synchronize the data with proprietary data in SiteManager. The Asphalt Mix Design software is developed using industry standard user interfaces and coding techniques to enable its easy maintenance and upgrade.
