Abstract
A heat and moisture transfer model for predicting the melting process of a snow/ice layer on a road is proposed in the present paper. Since the snow/ice layer is thin, 50mm or less, it is assumed to be uniform the model. The model is, therefore, called a ‘single layered model’.
It was found from the sensitivity analysis that (1) a calculation error becomes large for the thickness of the snow/ice layer more than 20mm, (2) the albedo and emissivity have stronger effect on the snow melting rate rather than the transmissivity and thermal contact resistance between the pavement and the snow/ice layer.
