We proudly welcome the City of Phoenix and the City of Peoria as our newest agency members. This expansion marks a pivotal moment in our mission to further strengthen our consortium’s commitment to bridging the gap between academia, industry, and public agencies.
Winners of the 2024 Best in Arizona Pavement Awards Program
We are delighted to share the winners of the first annual Best in Arizona Pavement Awards Program!
The awards celebration, held on the 20th of November, brought together industry professionals, project teams, and community leaders to honor outstanding asphalt pavement projects completed across Arizona.
Best in Arizona Award Program: PCDOT, ADOT, and MCDOT
The Pima County Department of Transportation, Arizona Department of Transportation, and Maricopa County Department of Transportation have demonstrated their commitment to road infrastructure innovation.
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
🤝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).
