Cleaning Mechanism to Remove Debris and Chemicals for Crack/Joint Sealing

This project will develop and demonstrate the use of a low-cost device using pneumatic power and rotary wire brushes to clean debris and chemicals from cracks and joints prior to sealing treatment. The project will be carried out in two stages. Work in the first stage will focus on designing and fabricating a prototype equipment for cleaning chemicals and debris from cracks and joints. A literature review will be conducted to uncover any past findings that could facilitate equipment development, in addition to gathering helpful feedback from industry through interviews and surveys. Additionally, on-site analyses of current crack and joint cleaning equipment and processes will be performed followed by a 3-D CAD modeling and fabrication of the initial prototype. The prototype will be tested in the laboratory and evaluated for mechanical durability, brush wear and effectiveness, air blast effectiveness, ergonomics, and equipment adaptability. Following necessary improvements, the prototype will be tested in the field in collaboration with the Nebraska Department of Roads (NDOR). Work in the second and final stage will involve further testing, evaluation, and refinement of the equipment as well as plans for commercialization. A business plan for commercialization of the equipment will be developed and interaction with industry will be established. The final report will provide all relevant data, guidelines and specifications for the new cracks/joints cleaning device and plans for its implementation by highway agencies.
