STUDENT SPOTLIGHT: Each month, or every other month, a student will provide a 1-page illustrated abstract of the research they are currently conducting. This is a wonderful opportunity for the student, for our International Society for Concrete Pavements (ISCP) Members, and for the transferring and sharing technology/research through our concrete paving industry.
The ISCP “STUDENT RESEARCH SPOTLIGHT” for May 2025 is Sunday Akanji, a PhD candidate in the Infrastructure and Environmental Systems Program at the University of North Carolina, Charlotte (Charlotte, USA).
BIO:
Sunday Akanji has been a PhD student for the past year and a half in the Infrastructure and Environmental Systems Program at the University of North Carolina, Charlotte. He is also simultaneously pursuing a MS in Construction and Facilities Engineering. Sunday has recently completed work on designing a novel 3D printed piezoelectric sensor for measuring stress in shear mode with applications in fluid dynamics. He has also been completing a project for NCDOT analyzing the impact of pumping boom configurations on the fresh and hardened air void system in pumped concrete.
TITLE:
Performance Engineered Concrete Mixtures (PEM)
Currently, Sunday’s research focuses on performance engineered concrete mixtures (PEM) to provide improved durability and sustainability. To support movement towards performance specification provisions, NCDOT has previously invested in two research studies and two pilot projects. These projects have provided an advanced understanding of testing and specification approaches that could be used to support PEM, shadow specification development and deployment on two pilot projects. Although proposed testing targets and initial pilot projects have been largely successful, additional laboratory testing, field trials and technology transfer are needed to support implementation of these approaches in upcoming NCDOT specification revisions.
Initiatives to lower embodied carbon, reduce greenhouse gas emissions, and mitigate other environmental impacts are underway at both federal and state levels. Although a number of the PEM approaches support more sustainable concrete, the environmental impacts of conventional and PEM concrete mixtures used by NCDOT for structures and pavements have not been quantified and compared to each other and to other types of construction. Quantification of the sustainability benefits of PEM concrete through life cycle analysis (LCA) is now possible using LCA frameworks supported by FHWA and other tools used in sustainability assessments. Quantification of the sustainability benefits (via LCA) and economic benefits (via life cycle cost analysis, LCCA) of conventional and PEM mixtures would allow NCDOT to understand cost savings associated with longer service life and reduced maintenance costs, improved performance due to an enhanced focus on quality during construction, and understand the link between laboratory test results and performance. This assessment would also assist NCDOT in meeting its goals and requirements to improve the sustainability of its concrete infrastructure. This project includes the third phase of work to support NCDOT’s movement towards implementation of performance-based provisions, with an added focus of quantifying the benefits of PEMs.
Objectives of this research are to 1) perform additional laboratory testing and evaluation to support development and deployment of PEM tests and mixture design approaches, 2) implement PEM tests and shadow specifications at additional projects (specifically bridge projects and pavement projects using optimized aggregate gradation mixtures and other PEM approaches), and 3) perform assessments of sustainability benefits (economic, environmental, and social) of PEMs using LCA and LCCA.
