Abstract

Abstract: In general, governments used to increase the number of public works for their economic recovery. In United State, huge number of bridges, roads and tunnels were constructed in 1920's. The lifetime of infrastructures is regarded as fifty years in general. In addition, the budget for maintenance of infrastructure had been decreased from the latter half of 1960s to 1970s. Therefore, most of these infrastructures were decayed in 1980's and this period is called as 'America in Ruins'. In Japan, enough number of power generators were required to launch heavy industries after World War II. To export these products, ports and highways were constructed. Furthermore, the bullet train 'Shinkansen' and urban expressways in Tokyo were constructed for Olympic game held in 1964. In 2010's, most of these infrastructures seem to reach their life time. However, government doesn't have enough budget for renovations. Therefore, new standards and technologies for repair and inspections are being required. Nowadays, huge number of infrastructures are under construction in Malaysia. Similar issues of United States or Japan may be occurred in this fifty years. In this paper, recent policy of government and new technologies including methods and equipment for maintenance of infrastructures in southern part of Japan are shown.
