Currently, asphalt mixtures are design using volumetric concepts to determine optimum asphalt content levels with no means of verifying mixture performance prior to field production and placement. A new design methodology called Balanced Mixture Design (BMD) promotes the use of evaluating and design asphalt mixture using rutting and fatigue cracking methods and criteria to achieve an optimum asphalt content that will result in an asphalt mixture performing well in rutting and fatigue cracking scenarios – thereby “balancing” the asphalt mixture performance.  MORE about Performance Evaluation of Asphalt Mixtures Statewide

The environmental and economic impacts of New York State’s waste-management system could be dramatically reduced by (a) decreasing the number of truck miles required to collect waste and (b) decreasing the demand for long-distance transport to remote disposal facilities.  MORE about Eliminating Trucks on Roosevelt Island for the Collection of Recyclables and Commercial Waste While Significantly Improving Energy Efficiency and Reducing Land Requirements

Project Description

It has been observed from recent studies that vehicular impacts to highway bridges are the 3rd leading cause of collapse of highway bridges. Recent data from the Federal Highway Administration (FHWA) and other studies show that the bridge overload and lateral impact from trucks, ships and train constitute 20% of the total bridge failures. The National Highway Traffic Safety Administration (NHTSA) estimates that annually 1000 buses or trucks (10,000 pounds gross weight or greater) collide with bridge structures.  MORE about Finite Element Simulation of Truck Impacts on Highway Bridge Piers
