DESIGN OF CIVIL AIRFIELD PAVEMENTS FOR SEASONAL FROST AND PERMAFROST CONDITIONS
A supply of water, freezing temperatures, and frost-susceptible soil is essential to cause frost action. The report describes the frost susceptibility of various FAA soil groups. The detrimental effects of the frost heaving of airfield pavements are controlled by using one of the following design methods: the complete protection method, the limited subgrade frost penetration method, or the reduced subgrade frost protection method. The detrimental effects of soil weakening due to thawing are minimized by applying the reduced subgrade strength design method. The modified Berggren equation and numerical methods for estimating frost and thaw depths are presented. Similar design methods are presented for airfield pavements in permafrost regions. A glossary of specialized terms used in the literature on frost and permafrost is included.
