Projects

Assessment of Thermal and Durability Cracks in Asphalt Pavements in the Southwest Region

🤝Sponsor: Southwest Pavement Technology
📅 2023 – Ongoing

Durability cracking in asphalt pavements is a major deterioration mechanism for asphalt concrete (AC) pavements in areas experiencing temperature and precipitation extremes. In this study, we develop a case study example of thermal and durability cracks widely observed in the Southwest of United States. Significant factors and root causes influencing occurrences of thermal durability cracks are presented using data compiled from forensic investigation of sites, field core characterization and mechanistic assessment of the conventional flexible pavement structures.

Development of Asphalt Concrete Mixture Long-Term Aging Protocol for Arizona’s Climatic Conditions

🤝Sponsor: Southwest Pavement Technology
📅 2023 – Ongoing

Field aging of asphalt concrete (AC) mixtures is a complex phenomenon resulting in significant changes in the rheological properties and chemistry of binders and impacting key performance characteristics of asphalt mixtures. Laboratory simulation of the field aging characteristics of asphalt concrete (AC) mixes is essential in characterizing its long-term performance. Hence, long-term aging protocols have become a key part of the Balanced Mix Design (BMD) framework adopted by many state and local agencies.

Construction Monitoring of Asphalt Pavement using UAV

Construction Monitoring of Asphalt Pavement using UAV

🤝Sponsor: NCIT

📅 2022 – Ongoing

The in-place density of asphalt pavements is a key indicator of construction quality, durability, and long-term performance. Pavement construction requires coordination and monitoring to ensure proper compaction which in-turn achieves the targeted in-place density. Two major factors hindering targeted in-place density are uniform mat temperature and uniform rolling pattern. The objective of this study is to develop an automated monitoring protocol with use of aerial images using uncrewed aerial vehicle (UAV).
