Comparing ﬁnite element and constitutive modelling techniques for predicting rutting of asphalt pavements Rashid K. Abu Al-Ruba*, Masoud K. Darabia, Chien-Wei Huangb, Eyad A. Masada,b and Dallas N. Littlea aZachry Department of Civil Engineering, Texas A&M University, College Station, TX , USA; bMechanical Engineering Program, Texas A&M University at Qatar, . The model combines a heat-transfer model for evaluating frost conditions and temperature-related effects, with an elastic layer model for stress and deflection determination. The heat-transfer portion of the model was derived from one-dimensional, forward .
A second situation (frost heave) can also develop if the frost depth increases to the point where freezing occurs under the foundation. If the soil expands upon freezing (frost susceptible soil) large uplifting forces can be applied to the foundation system . If foundation designers are to avoid these problems, they require informa- tion. Prozzi, Gossain and Manuel Page 5 MR = the effective roadbed soil resilient modulus. To take local precipitation and drainage conditions into account, Equation 8 was modified to Equation SN = a1D1 + a2m2D2 + a3m3D3 (11) m2: drainage coefficient of base course. m3: drainage coefficient of subbase course. Equation 10 is the performance equation which gives the .
This work presented the development and validation of an analytical method to predict the transient temperature field in the asphalt pavement. The governing equation for heat transfer was based on heat conduction radiation and convection. An innovative time-dependent function was proposed to predict the pavement surface temperature with solar radiation and Cited by: 3. Time-of-Wetness and Time-of-Freezing Predictions. The wetting and freezing events for 12 representative geographical locations are summarized in Tables 2 and is easily observed that there is considerable variability in time-of-wetness and .

FROST HEAVE is the raising of a surface due to formation of ice in the underlying soil. FROST-MELTING PERIOD is an interval of the year when the ice in base. The modelling of frost heave development within the soil is an important aspect in the computational treatment of the interaction problem.
This paper deals with the calibration of a three-dimensional computational approach for the study of frost heave development, which takes into consideration the.
PAVEMENT DESIGN METHODS: A LITERATURE SURVEY INTO LINEAR-ELASTIC THEORY AND CONDITION PREDICTION MODELS. This report presents the results of a literature survey into design methods for asphaltic pavements, discussing: 1) the applicability of the Linear Elastic Multilayer Theory (LEMT) in the calculation of pavement stresses and strains; and 2) condition.
We present a laboratory system designed for studying frost heave in fine-grained soil. The system consists of: a modified refrigerator, a frost heave test cell, a laser for measuring heave, a differential pressure transducer for measuring water intake, and platinum resistance temperature detectors for measuring pedestal temperatures.
A model of the frost heave phenomenon in soil was developed. This model predicts ice lensing and heave rates as a function of the basic soil properties (thermal conductivities and particle size) and the externally applied boundary conditions (surface temperatures and overburden pressure).Cited by: cided to use a finite element model that represents a continuously supported slab rather than a more generalized finite element model such as the model developed by Wilson (8) and modified by others.
