Winter tenting of highway pavements : test program and discussion of causes and mechanisms by Maureen A Kestler( Book )

2 editions published in 2000 in English and held by 12 WorldCat member libraries worldwide

Tenting consists of localized frost heaving in the immediate vicinity of transverse pavement cracks. It produces a highly irregular riding surface, leads to premature pavement-surface deterioration, occurs on highways designed for high traffic volumes and to withstand freezing and thawing, and is frequently exhibited by pavements in otherwise good condition. The objective of the project discussed was to investigate causes and mechanics of the phenomenon. Several transverse cracks at four test sites were monitored for salt concentration, moisture content, subsurface temperature, freezing point depression, and heaving throughout several winter/spring seasons
Thaw weakening and load restriction practices on low volume roads by Maureen A Kestler( Book )

2 editions published in 2000 in English and held by 11 WorldCat member libraries worldwide

Low volume roads subjected to seasonal freezing are highly susceptible to damage from traffic during midwinter and spring thaws. Such traffic-induced damage can be minimized by a variety of design methods; however, most are not economically feasible. As a result, loads are often restricted or prohibited during thaw-weakened periods. While this practice reduces road maintenance costs, the economic impact on industries that rely on continued heavy trucking can be significant. This report reviews the process of ice segregation and thaw weakening, and then discusses both quantitative and qualitative results from a survey on load restriction practices that was distributed to state departments of transportation (DOTs). Survey topics include state DOT load restriction practices, types and mileage of roads posted, methods for determining dates for imposing and removing load restrictions, enforcement of restrictions, and feedback from road users
