Outline of Final Research Achievements

This study investigates basic thermal properties of sidewalk pavement block to improve environment in big city during summer. The temperature history in a day is measured for various types of pavement block. Then the influence of aggregate mineralogy, mixture proportions, surface shape or texture of sunny side, surface area of bottom side on maximum temperature, temperature rise and down velocity. The quantification index for the properties are also given in this study.
The results of this study gives effective mixture proportion, surface shape and texture, and surface shape or surface area of bottom side to improve thermal properties of sidewalk pavement block in summer. The impacts of these factors are also given by the study.
