Effect of Temperature Variation on Rigid Pavement by using Sensor

Abstract

Abstract: Variations in temperature have an impact on both stiff and flexible pavements. Although the main component of pavements is crushed stone aggregate, which is not temperature-sensitive, the binder that holds the aggregates together is more temperature-sensitive. Pavements made of Portland cement concrete (PCC) that are cast in the field experience volume fluctuations as a result of changes in temperature and moisture. Utilize sensors to examine the impact of temperature and moisture change on stiff pavement. Analyze the technical and physical characteristics of sensors. locating sensors in solid pavement in order to get accurate data. This research aims to analyze temperature differences for stiff pavement (mainly for the PQC layer). Table 1 in IRC:58-2015 lists the temperature differences for several Indian areas. In order to design pavement slabs of varied thicknesses, it offers temperature differential values. However, the table's footer also states that the data was collected in 1974 by the Government Road Experiment Station in New Delhi. This analysis is done to compare the temperature difference between that table, which is over 50 years old, and the present temperature. It has been noted that temperature measurements obtained from a temperature sensor closely match the information provided by the metrological department. (Data on temperatures from July to November) Data from the prior 10 years are collected for further examination when data from the IMD is confirmed to be the same (2012 to 2021). The temperature disparity over the next 10 years is forecasted using those data (2022 to 2031). When compared to IRC, data have revealed a rise in the minimum and maximum temperature disparity.
