Abstract:
The use of expansive cement in continuously reinforced and prestressed concrete pavements could be effective not only in comprensating drying shrinkage of concrete pavements but also in inducing a self-stress due to the restraint of expansion by subgrade friction and reinforcement, if the expansion of ocncrete due to expansive cement existed sufficiently for a long period. Therefore the application of expansive cement to concrete pavements were examined experimentally in the laboratory and field work.
