The effect of evaporative cooling of three kinds of water-absorbing percolation asphalts which made for trial purpose has been examined and it has been found that there is little water absorbing capacity of the percolation asphalt and the water-absorbing percolation asphalt has water absorbing capacity of 5cm at least and the content of barmicurait has a big influence on the water absorbing property. Since these experimental materials used are those immediately after making, the influence of the moisture transfer over along time on the behavior of cement in the sample has not been considered. In the present paper, the deterioration with age of the evaporation performance of the water-absorbing percolation asphalts is examined. The surface temperature and the amount of evaporation are numerically investigated under the same condition with experiment. The influence of moist transfer coefficient on the insolating wet surface temperature of the materials is also examined.
