The goals of this thesis research are to characterize emissions from construction equipment such as a Road Miner and Chain Trencher, develop and compare preliminary alternative designs for collection of emitted dust, and evaluate the potential economic and operational benefits of improved dust control technology; Data collected from two site visits using PM-10 DUSTTRAKRTM monitors, video camera, digital photo camera, and soil samples; served as a data source to analyze construction operations, delineate sources of emissions, and characterize emissions; Preliminary designs using vacuum and water spray dust control systems were developed for a Trencor Road Miner and a Trencor Chain Trencher. Costs for each vacuum and water spray system were evaluated and compared to find the best suitable alternative for both equipments; A water spray system proved more feasible for a Chain Trencher and a Vacuum system is recommended for a Road Miner for dust control; This thesis demonstrates strong potential for construction industry to improve productivity and reduce wait times, while complying with local regional and national air quality standards.
