Paper, 2002Beskrivning: 10 sÄmnen: Bibl.nr: VTI 2002.0071Location: Abstrakt: Snow and ice control is generally implemented by mechanical equipment. Japan Highway Public Corporation (referred to as JH below), responsible for construction and management of expressways, uses about 1,000 snowploughs and 500 anti-icing chemical spreaders for around-the-clock highway maintenance. Annual costs of snow and ice control on expressways amount to 200 million dollars. As anti-icing chemical, 150 to 200 thousands of tons of sodium chloride are used annually. With an increase of the length of expressways to be managed, JH has been requested to control road surface more efficiently during winter. This paper outlines systems aimed at increasing the efficiency of snow and ice control during winter, and reports the status of system development. The snow and ice control systems produce various benefits as (1) level of service improvement; (2) uniform work setup; (3) cost reduction; and (4) minimization of environmental impact.| Aktuellt bibliotek | Status | |
