Pavement Preservation

Pavement preservation research focuses on developing and implementing strategies to extend the service life of transportation infrastructure. This area investigates the performance of various pavement materials, including asphalt binders, aggregates, and additives, under diverse environmental and loading conditions. Research explores the use of innovative materials and technologies, such as asphalt emulsions and recycled materials, to improve pavement durability and sustainability. Methodologies include laboratory testing of material properties, field performance monitoring, and the development of predictive models for pavement distress and rehabilitation needs. Key sub-fields encompass asphalt emulsion technology, aggregate-binder compatibility, and the utilization of waste materials in pavement construction.

This research is particularly relevant to Arkansas, given the state's extensive network of roadways and its significant agricultural and industrial sectors, which rely heavily on efficient transportation. Maintaining and improving pavement infrastructure supports economic development by facilitating the movement of goods and people. Furthermore, research into sustainable materials and practices can help reduce the environmental impact of road construction and maintenance, aligning with state goals for resource management and conservation. The development of longer-lasting pavements also contributes to public safety and reduces long-term costs for taxpayers.

This research area draws upon expertise in materials science and pavement engineering. Engagement with related fields like waste plastic utilization and aggregate-binder compatibility allows for a comprehensive approach to developing advanced pavement solutions. The work involves collaboration across institutions to address the complex challenges of modern infrastructure maintenance.
