摘要：The present paper is based on the assumption that the temperature distribution is linear throughout the depthof the slab. Temperature is one of the important loads for designing slab track. The characteristic of slab track temperaturevaries greatly with different regional climates. This is an approximation, because studies have shown that the actualdistribution is nonlinear. The combined effect of load and temperature variation is responsible for the development ofcritical stresses. Concrete is a man-made material produced by the proper mixing of cement, coarse aggregate, fineaggregate-natural or M-sand and an adequate and controlled amount of water, with or without super plasticizers. Threedifferent mix proportion models of (S1) cast with N-sand, (S2) cast with M-sand and (S3) cast with equal proportion of Msandand N-sand were prepared. The analysis is based on the temperature variation is linear throughout the depth of themodels. Three modules of different material properties are cast, instrumented with K-type thermocouples at different levelsviz., top, middle and bottom and the actual temperature in the models are recorded every hour for 28 days using a digitaltemperature recorder. The temperature were found using the Thermocouples. Hence it is necessary to analyze the modelsfor Thermal and Structural loadings. The result obtained from the study clearly shows that the actual temperature variationsare Non-linear. The present finding confirmed the importance and the need to account the nonlinear temperature variationin the design of concrete pavements. Hence, an attempt has been made in this study to evaluate the effect of actualtemperature variation across the thickness of the models.
