Evaluating Equilibrium Matric Suctions under Pavement System Based on Thornthwaite Moisture Index (TMI)
Equilibrium moisture beneath highway pavements is a critical parameter that affects the strength and stiffness of pavement systems and controls the pavement design. The soil moisture content can be expressed in form of soil suction by means of the soil water characteristic curve (SWCC). Previous research studies have shown a correlation between soil suction and Thornthwaite’s moisture index (TMI); however, these suction correlations exhibit large variability. The paper assessed the TMI from the historical climatic data obtained from Oklahoma Mesonet weather stations data from 1994 to 2017. Two commonly used models used to calculate the TMI values from the historical climatic data and contour maps are constructed. On the basis of the field data and numerical modeling, the paper builds a relationship between equilibrium suction of subgrade soils, TMI, relative humidity, and clay content.
