Design method of crack-resistant cement stabilized macadam based on interface weakening
The invention discloses an interface weakening-based anti-crack cement stabilized macadam design method, and provides an energy evolution calculation method of a pavement structure and a pavement cracking failure mechanism aiming at the problems that the current semi-rigid base pavement anti-crack design depends on experience, the design process is complicated and the anti-crack effect is unstable. And determining the mix proportion design step of the anti-crack cement stabilized macadam based on energy calculation and analysis. According to the anti-crack cement stabilized macadam designed according to the method, material design is guided through theoretical calculation, anti-crack performance optimization is more purposeful and effective, the comprehensive application effect is better, the design process is more reasonable, application and popularization of advanced anti-crack design of a pavement structure are facilitated, and design and use of the anti-crack cement stabilized macadam in actual engineering are facilitated.
本发明公开了一种基于界面弱化的抗裂式水泥稳定碎石设计方法，针对当前半刚性基层路面抗裂设计依赖经验、设计流程繁杂、抗裂效果不稳定的问题，提出路面结构的能量演化计算方法和路面开裂破坏机理，再基于能量计算分析来明确抗裂式水泥稳定碎石的配合比设计步骤。依据以上方法设计的抗裂式水泥稳定碎石，由理论计算指导材料设计，抗裂性能优化更具目的性、有效性，综合运用效果更佳，设计流程更合理，有利于路面结构先进抗裂设计的推广应用，有助于抗裂式水泥稳定碎石在实际工程中设计和使用。
