Abstract: In virtue of fracture mechanics,the authors analyzed the anti-cracking and tenacity increasing mechanism of flexi- ble fiber in flexible fiber cement-stabilized material semi-ri6d base,and carried out a relevant experimental study.The analysis and experimental stray show that the flexible fiber cement-stabilized material is a new semi-rigid base with eminent anti- crack,anti-shrinkage,anti-fatigue,anti-impact performance and good tenacity.Application of this new style base will resolve the early age cracking of the existing bases efectively,improve the service-life of pavement structure impressively and have a notable impact on economic eficiency and social importance.

Key words: flexible fiber, cement-stabilized material semi-rind base, anti-cracking and tenacity increasing mechanism, anti-crack performance, experimental study
