15/1/2017 · Two domains were classified as the macro domain which represents the external environment above a pavement surface and the micro domain which represents the RPSC pipe embedded underneath a pavement. For the macro domain, the temperature of a road surface was assumed to be influenced by five variables: (i) solar radiation, (ii) air flow, (iii) canyon geometry, (iv)
