 HIGH SPEED OVAL TRACKS-BANKED CURVE PAVEMENT

The origin of our creation and developments of the Banked Curve Pavement is traced back to the era of rapid economic growth in Japan in arround 1960's.

In this era, the volume of vehicle traffics was dramatically mounted up and the automotive development had been domestically proceeded in Japan. In an environment marked by these grounds, as a result of the test run of the several vehicles imported and/or domestically developed held in the first Japanese expressway which was just constructed by NIPPO, it fallen out that an overwhelmingly superior performance of foreign vehicles was confronted in comparison with domestics.
This marked the beginning of the engagements with upgrading of domestic vehicles by the Japanese automotive companies and developments of paving technology by NIPPO to actualize provide the test track which has 42° cross incline banked curve. Thus NIPPO succeeded in the first banked curve pavement in Japan in 1966. Our challenges to develop the paving to create the transition curve on tracks is the history of this paving technology in Japan. With our technology amassed by the histry which has moved hand-in-hand with the development of Japanese Automotive Industory being involved in 95% of the projects of banked curve paving in Japan, the confidence and expectations to top quality of our technology to create banked curve pavement is broadening worldwide thereafter.

 Expansion in Application of Banked Curve Pavement

The banked curve paving technology created for development of automotive test tracks is expanded for the pavement of Velodrome which is required to have McConnell Transition Curves as with automotive test tracks.
