Project Title: A New Generation of Environmentally-Friendly Asphalt Emulsion: Advancing Sustainable Infrastructure Solutions
Performing Institutions: Louisiana State University and University of Arkansas
Principal Investigator: Mostafa Elseifi, Louisiana State University; Andrew F. Braham, University of Arkansas
Proposed Start and End Date: 0/01/2024 to 09/30/2025
Project Description: Hot applied asphalt cement, cutback asphalt, and emulsified asphalt have been used as tack coats and for chip seal applications. However, emulsified asphalt tack coats have been widely favored due to their additional benefits, such as reduced energy consumption, lower environmental impacts, and improved worker safety. The objective of this study is to conceive, test, and evaluate a new generation of environmentally-friendly “green” emulsified asphalt with lower environmental impacts than regular emulsified asphalts but with comparable performance. If successful, the proposed product may be used as an available environmentally friendly emulsified asphalt in the market. State and federal agencies will be interested in the proposed product in order to minimize the environmental impacts associated with road construction. Asphalt producers and suppliers will also be interested in adopting the new generation of emulsified asphalts to ensure that their products are tailored to the market needs in different parts of the country.
