Time-Dependent Behaviour of Roller Compacted Concrete Pavements

Roller compacted concrete pavements (RCCP) have been increasingly constructed in many places in Japan. However, the behaviour of RCCP in the areas of joints and cracked sections has not been completely cleared. In order to establish a rational thickness design of RCCP and to study long-term behaviour of RCCP and the effectiveness of load transfer at joints and cracked sections a trial RCCP with different pavement structures and joint spacings is examined in this paper. As a result. it has been observed that it is important to control early age cracking and to strengthen the base course with a cement treated base (CTS).
