Abstract
This research aims to study the liquid limit, plastic limit, and plasticity index of soil samples treated with elevated temperatures. Liquid limit and plastic limit are physical properties of soils. Bentonite, kaolin, and Pasir Panjang samples were heated in an oven from room temperature up to 100 °C before the test. The liquid limit and plastic limit of soil samples were examined by Casagrande’s cup test and fall cone penetrometer test. Results show that the liquid limit and plastic limit of soil samples decrease as temperature increases. Plasticity index varies with the change in liquid limit and plastic limit. The bentonite sample is the most sensitive to temperature change, whereas the kaolin sample is the most insensitive. The sensitivity of the Pasir Panjang sample is in between those of the two other samples.
