Abstract
Composite bridge which had been developed in western countries was introuduced to Japan after the Second World War. Bridges in composite construction were sharply ineresed and reached the peak in 1970's.
The first standard specification for composite road bridges was also established in the 1960's. After the beginning of the 1980's onword, composite bridges had lost popularity because of frequent failures of reinforced concrete slabs due to increasing traffic laod and now, compsite bridge has been a minor solution for bridge construction. In this paper the development of composite road bridges both in western countries and Japan are clarified to examine one of the characteristics of Japanese bridge tecchnologies.
