INSTALLATION AND FOLLOW-UP EVALUATION OF DRAINING PAVEMENT ON HIGHWAYS

Kobe Route of the Hanshin Expressway received extensive damage from the Hyogo Nambu Earthquake (Great Hanshin Earthquake) in January 1995. While restoration work was in progress, the Supreme Court made a decision in July 1995 on the National Route 43 Suit, which was a traffic noise pollution suit involving the Hanshin Expressway. The National Route 43 and Hanshin Expressway Kobe Route Environmental Improvement Meeting organized by the Hanshin Expressway Public Corporation (HEPC) and other concerned organizations examined measures required to comply with the decision. As one of the environmental measures, drainage pavement which had a noise reduction effect was adopted for restoration of the Kobe Route, which forms a combined sectional structure with National Route 43. The total area installed with drainage pavement was about 3,000,000 square metres as of 1995, and most of the area was on earthwork structures. Therefore, the durability of the pavement and endurance of the noise reduction effectiveness were not known for elevated roads under heavy traffic load such as the Kobe Route. The Pavement Durability Improvement Survey and Research Committee of the HEPC examined the applicability of drainage pavement to highways through various laboratory tests and test installations. After duly reviewing the results, the committee established its "Low noise pavement on highways: A proposed manual for the design and installation of draining pavement for traffic noise reduction" in April 1996. Drainage pavement was installed on concrete slabs (including prestressed concrete girders) and steel decks in accordance with the manual, and all the restoration work for the Kobe Route was completed. This paper describes the first large-scale application of drainage pavement to the surface of continuous bridges in Japan, and also includes interim reports of follow-up evaluations which have been conducted regularly after the installation, to indicate the current situation and future direction of drainage pavement on highways.
