| Abstract: | In virtue of fracture mechanics,the authors analyzed the anti-cracking and tenacity increasing mechanism of flexible fiber in flexible fiber cement-stabilized material semi-rigid base,and carried out a relevant experimental study.The analysis and experimental study 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 effectively,improve the service-life of pavement structure impressively and have a notable impact on economic efficiency and social importance. |
