A Quantitative Investigation of the Durability of Asphalt Pavement Materials Using Experimental Freeze-and-Thaw Weathering Data

This paper highlights trends in asphalt concrete damages due to freeze-and-thaw cycles. Various independent parameters, such as thermal and chemical conditions, and their combined actions contribute to these damages and reduce the service life of asphalt pavements. The existing literature is rich on the effect of freeze-and-thaw cycles in presence of deicing chemicals. Further, the assessment of damages in respect to physical, chemical, and mechanical characteristics of asphalt pavement materials has gained extensive attention in academic research and practice projects. The presented investigation examines the observed trends of damages due to various material properties and environmental conditions and aims to offer quantifiable performance measures to assess the sustainability and resilience of asphalt materials in response to severe conditions. Essential properties of asphalt materials include permeability, the porosity of aggregates, presence of chemicals or salts, water flow and pressure, chemical stability of aggregates, and applied cycles of freezing and thawing. Reported measures typically include weight loss and strength reduction. Conclusions highlight participating factors in determining the service life of asphalt pavements and associated costs and environmental footprints of transportation infrastructure.
