DEVELPOMENTS IN HIGHWAY PAVEMENT ENGINEERING--2. CHAPTER 3. FROST HEAVE DAMAGE AND ITS PREVENTION

Frost heaving and associated thaw weakening arising from a combination of freezing temperatures, frost susceptible materials and the availability of water, cause loss of riding quality and possible permanent damage to roads. The mechanism of the heaving process is reviewed and recent developments in mathematical models presented. Methods of assessing frost susceptibility are examined critically. Both direct tests, including the proposed revision to the TRRL test to accommodate self refrigerating units and indirect assessments, with particular reference to the role of suction characteristics, are discussed. A framework is proposed for a revised design procedure in which the ground water level and the capillarity and permeability of the subgrade are considered. Whilst the chapter is orientated towards British conditions and problems with unbound materials, much of the content is of general application. /Author/
