CHARACTERIZATION OF THE METEROROLOGICAL DEMAND FOR THE DESIGN OF VERTICAL MOISTURE BARRIERS. Academic Article

abstract

• Pavements founded on expansive soils are damaged because of seasonal wetting and drying of the foundation soils. The magnitude of the damage is controlled by the wettest and driest moisture content profiles that occur at the site. The moisture profiles are altered with the removal or replenishment of soil moisture by the meteorological conditions. Because weather conditions cannot be predicted accurately, the extreme moisture content profiles are stochastic. The purpose of this study is to characterize the wettest and driest moisture content profiles that have the desired probability of occurrence during the lifetime of the pavement. The wettest and driest profiles are associated with the respective annual maximum and minimum depths of water stored in the soil profile. 31 Refs.
