WORLD TRENDS. SUSPENDED ROAD SAFE FROM WINDS

Unique construction and traffic management measures were reported at the Seventh Conference of the Road Engineering Association of Asia and Australia, in Singapore in June 1992. In Hong Kong, a major new motorway will connect Kowloon with Hong Kong's new international airport. The motorway incorporates a number of bridges, notably the Tsing Ma Bridge, which will carry traffic more than 700 ft above an inlet of the South China Sea. Concerned by its exposure to typhoons, a suspended, shielded, 2-lane roadway was constructed beneath the main deck. Trucks will be diverted from the main deck to the lower deck when winds reach 37 mph, and all vehicles will use the lower deck when winds reach 70 mph. Japan's construction of elevated expressways on central piers about 80 ft high, with apartment houses, shops and business offices underneath is described. In Malaysia, oil from a species of palm tree is being tested as an extender and additive for hot-mix asphalt. Also reported, was Japan's successful experience with roller compacted concrete pavement. A fully automated computer-based system which analyzes heavy loads and routes them over South Australian roads was also noted.
