An actual analysis of super road maintenance in the Shirasu area, Southern Kyushu, Japan.
- Other Title
<p>We conducted actual analyses of the maintenance of 98 spur roads running of a medium truck in the Shirasu area(formed from the pyroclastic flow deposits from Aira Caldera) of Southern Kyushu. Most of the spur roads in the study had been established for 4-6 years. Eighty percent of the maintenance of sites was required due to clearing and grubbing and non-land correction of trucks and for concretization of the road surface and granular filling of the roadbed. About 90% of maintenance costs were due to concretization of the road surfaces and granular fill used for the roadbed. Costs increased as the number of years after the establishment of the roads increased. After 16 years, the total cost of maintenance of the spur roads is expected to be > 25% of their establishment costs.</p>
