Crushed-rock air convection embankment (ACE) has been used to mitigate pavement distresses caused by climatic extremes in permafrost regions for more than three decades. This study proposes using lightweight aggregates as cost-effective alternative materials to overcome the shortage of desired crushed rocks needed for ACE in interior Alaska. This paper presents an investigation of the performance of six selected pavement structures: an asphalt pavement typical of the northern region of Alaska and five pavements reinforced with different paving interlayers (i.e., silty sand/gravel, crushed rocks, cellular concrete aggregate, foam glass aggregate, and lightweight expanded clay aggregate). Pavement thermal analyses using Temperature Estimate Model for Pavement Structures (TEMPS) program and ANSYS Fluent software were performed to predict heat transfer patterns and thermal performance for each case. Pavement performance analyses using viscoelastic-based FlexPAVE™ and the elastic-based Alaska Flexible Pavement Design (AKFPD) program were conducted to evaluate the long-term performance and structural stability of subgrade soil with different types of interlayers. The results showed that the lightweight aggregate ACEs improved cooling performance more effectively than the crushed-rock ACE. The lightweight aggregate interlayers could maintain desired thermal insulation in summer and enhance the cooling effect in winter. The modeling results identified the high potential of using lightweight aggregates as alternative ACE materials to improve pavement service life and subgrade stability.

The cell morphology of polymer foam shows an essential role in its functional attributes and its lightweight and thermal dependency cause diverse applications in building, utility lines and road structures. The most used polymer materials are flexible, structural and speciality foams. Phenolic foam, a member of speciality foam family, is produced through curing and expanding process with a composition of phenolic resin, surfactant, curing catalyst and blowing agent. The characteristics of phenolic foams (PF) in absorbing liquids and dissipating energy through collisions and shocks urge its application in road construction and airfield pavements. This chapter discusses the physical properties and the usages and benefits of PF for road and airfield pavements in the cold regions. The PF provides thermal efficiency and soft ground arrestor in pavements avoiding the overrunning of vehicles and aircraft. The open cell PF, as a geotextile layer in the permeable pavement systems (PPS), has also potential to retain and harvest rainwater. The PF layer under the porous friction asphalt of PPS delays the peak flow of rainwater during the extreme rainfall events and minimises the flooding risk.
