Title: A Functionally Optimized Hot-Mix Asphalt Surface Course
Contact: Soundar Balakumaran
Associate Director for Structures
Project No.: 86359
Target Date: 04/16/2009
Abstract: The proposed project will oversee the design, production and placement of a new-generation, open-graded surface course.  Although concerned with all functional aspects of a highway wearing course, the data acquisition, analysis and reporting goals of this project will conform to the requirements of the Federal Highway Administration’s Tire/Pavement Noise Research program.   In that respect, the acoustic characteristics of the new surface and the way these characteristics translate into reduced noise levels along the facility will be carefully measured and reported.  In addition to noise and noise-related properties, safety and ride quality will be evaluated, as well as more subjective characteristics such as splash and spray, wet-night and pavement-marker visibility. Structural preservation also will be addressed.
