摘要
为减少沥青路面的早期破坏,在分析国内外沥青路面设计理论及车辙预估模型的基础上,提出以车辙为设计指标的设想,给出了以车辙作为主要控制指标的设计流程,再以实例的形式给出了车辙预估的整个过程,并对计算结果做了相应的分析,认为单以弯沉作为沥青路面的设计指标并不能控制路面的早期破坏,建议在现行沥青路面设计规范中增加车辙设计指标,完善沥青路面设计理论,从而保证沥青路面的使用寿命.
On the basis of the analysis of domestic and international asphalt pavement design theory and rut forecast model, it is proposed that rut should be given as a control index in the design process in order to reduce the early damage of the asphalt pavement. Then an example is given in the form of a forecast in the whole process, After analyzing the result, it is shown that the road is beyond the control of the early damage as the only design index is deflection. So it is proposed that the Asphalt Pavement Design Standards should take in the rut as an index. It is expected that asphalt pavement design theory can be improved and the asphalt pavement can have a relatively long life expectancy.
