Bottom ash produced from coal-fired power plants has been utilized in engineering
applications for the purpose of recycling and solving disposal issue of bottom ash. This study …

Extremely low temperatures and freeze-thaw cycles cause premature cracking and low
pavement bearing capacity. However, insulation layers could influence the extent of the …

Insulated pavement structures help prevent frost penetration and its negative impacts on
roadways and airfields in cold regions. The most commonly used insulating material in …

Polymer materials, such as extruded polystyrene (XPS), polyurethane (PU) and polystyrene
(EPS), are extensively used as thermal insulators in cold regions to protect the engineering …

This study was to present changes on the thermal conductivity and structures of silty clay
(SC) modified by waste fly ash (FA) and oil shale ash (OSA) after freeze–thaw (FT) cycles …

To protect pavement in cold regions, insulation layers have been used in pavement
construction. The insulation layer blocks the heat exchange, resulting in different pavement …

Laying insulation material is an effectively method to deal with the frost damages. In the
engineering practice, the insulation material will be exposed to water and freezing-thawing …

Pavements constructed on frost-susceptible subgrade layers are prone to deterioration from
freezing in cold regions. A thermal insulation layer above the frost-susceptible subgrade …

Subgrade moisture content significantly influences soil strength and pavement bearing
capacity. Pavement moisture content varies greatly throughout the year, especially in cold …

Including insulation layers in pavement structures has become a common strategy to
minimize frost penetration in cold regions. This study investigated the performance of two …
