ABSTRACT
These days, pedestrian-friendly soil pavement design has been drawing people’s attention in terms of environmental protection, global warming and alleviation of heat-island effect. The current pedestrian-friendly pavement design decides the composition of the pavement according to soil selected on past experience. Therefore, in the current situation, there are no clear criteria for a required performance of pavement. The main fields of pedestrian-friendly pavement are limited to the park, garden, path, and river bed in terms of strength of the pavement materials and being comfortable for pedestrians. However, if durability of pavement is improved, its utilization of pavement material would be expanded also coal ash from facilities including the fire power stations in 2005 reached about 11.15 million tons, and increase shows about 300,000 tons, compared with the previous year. In addition, the demand for coal power generation in the electric industry has been increasing due to the influence of rising price of crude oil in recent years. Considering these matters, coal ash is expected to continue increasing. Effective use of coal ash accounts for about 96% of total. However, the rest of ash has been reclaimed in the disposal site. In future, because it has become difficult to secure a large scale of disposal sites, expanding effective utilization becomes crucial issue. It is known
that coal ash becomes a solidification material similar to cement by combustion technology. In this study, we focused on the fiber as materials for remedy of brittle failure.
