Degradation Process of Doweled Transverse Joint of 30 Years Old Concrete Pavement on Expressway in Japan

Autor: Tatsuo Nishizawa, Kenji Takai, Naofumi Noro, Nobuhiro Kurato, Yasuhiro Nakamura

Publikováno v: Proceedings of the 12th International Conference on Concrete Pavements.

A section of jointed concrete pavement on Tokai-Hokuriku Expressway in the central region of Japan main island was opened in 1986. After 30 year service, small faulting has begun to appear at many joints. In order to grasp the entire situation of the

Publikováno v: Proceedings of the 12th International Conference on Concrete Pavements.

A 7 km section of CRCP was constructed on the Ban-Etsu Expressway, which was opened in October 1990, in heavy snowy region of the Japan main island. Transverse cracks had opened wide and the crack spacing had become shorter just after 9 year service,

Structural Evaluation of the Transverse Joint of a Concrete Pavement Considering the Degradation Process

Autor: Yuya Wakabayashi, Tatsuo Nishizawa, Masayuki Yabu, Masataka Uchida

Publikováno v: Transportation Research Record: Journal of the Transportation Research Board. 2673:319-328

Effective maintenance of a concrete pavement requires precise evaluation of the load transfer efficiency (LTE) at the transverse joint, which is simply calculated from the falling weight deflectometer (FWD) deflections at the loaded and unloaded slab

State-of-the-art of interlocking concrete block pavement technology in Japan as a post-modern pavement

Autor: Ali Jamshidi, Kiyofumi Kurumisawa, Jize Mao, Tatsuo Nishizawa, Toyoharu Nawa, Gregory W White, Toshifumi Igarashi

Publikováno v: Construction and Building Materials. 200:713-755

Researchers dealing with pavements and experts on materials have been increasingly focused on the structural strength of the pavement materials without paying sufficient attention to the environment and cultural norms. In the 21st century, the concep

Thermal Stress Calculation Method for Concrete Pavement Based on Temperature Prediction and Finite Element Method Analysis

Autor: Toru Yoshimoto, Tatsuo Nishizawa, Yasusi Takeuchi, Masashi Koyanagawa, Kazuyuki Kubo

Publikováno v: Transportation Research Record: Journal of the Transportation Research Board. 2640:104-114

A method to predict thermal stress of a concrete slab was developed in this study. In this method, temperatures and thermal stresses in a concrete slab are predicted by solving a one-dimensional heat transfer equation with the control volume method a
