| Research Abstract |
A porous concrete has properties of high water permeability and water retentivity and is used as a pavement material. Thermal and moisture properties of porous concretes with different void fractions were measured and identified in order to calculate a thermal behavior of porous concrete pavement with simultaneous heat and moisture transfer equations. The calculated results for a thermal behavior of the porous concrete agreed well with results of field experiment. Numerical analyses of heat and moisture behavior for both various pavement and surface ground was conducted and it was found that the porous concrete pavement is much less than a bare ground in effect of evaporative cooling.
