Coral Reef Rock (C.R.R.) is a sort of the limestones and consists of coral corps, shells, marine organisims and plants, and those are chemically changed into the calcium carbonates (mostly calcites) because of geological diastrophism of the Ryukyu Islands. This C.R.R. is one of the prospective natural resources in the Ryukyu Islands, and it has been used conventionally as the road construction materials. As a part of the series of soil-base stabilization studies, C.R.R. is experimentally investigated to improve the local base materials of Okinawa Islands. Present paper describes the outline of the geology of Okinawa Islands, the distribution of C.R.R. and its reserves and minings, and reports the laboratory test results concerning the physical properties, compaction effects, compressive strength and C.B.R. of C.R.R. only and cement-treated C.R.R. Also experiments were performed to investigate into the strength restoration characteristics and the strength increasing method by heating C.R.R. test pieces
