Abstract
The soils distributed in Jeju area are volcanic ash soils generated from the basalts. volcanic ash soils are consisted of volcanic ash, volcanic sand, lapilli and scoria, and they are varied with clay and gravel. The purpose of this study is to indicate the area which can be utilized as subgrade soil materials After comparing the soil test results of 167 soils sampled from 39 areas with the road design criteria of subgrade soil materials.
For the classification results of USCS, 114 samples in 24 areas, 68% of total samples could be utilized as the subgrade soil. And for the classification results of AASHTO, 68 samples in 29 areas, 40.7% of tatal samples could be utilized as the subgrade soil. Also for the analysis results of consistency of soil and sieve analysis, 45 samples in 23 areas, 26.9% of total samples could be utilized as the subgrade soil and when considering the number of area rate, 59% of total area could be utilized as the subgrade soil. When the test results of soils sampled from Jeju area compare with the road design criteria of subgrade soil materials, although soils sampled from Jeju area aren't suitable as the upper subgrade soil materials, for lower subgrade soil materials about 30% utilization are indicated. This results present that for the classification of the soils distributed in Jeju area as the subgrade soil material AASHTO is more suitable than USCS.
