摘要
路面结构强度随使用年限的增加而衰减,按使用期末的容许弯沉设计路面隐含着不安全因素,故建议按初始弯沉计算路面厚度。初始弯沉可用相关关系法或强度补偿法予以确定。
Tests and researches proved that the strength of flexible pavement
attenuates with time, therefore, designing the flexible pavement with the allowable
deflection at the end of serviceabitiy life of pavement as an index implies an unsafety
of the pavement structures. This paper presents a method that calculates the thickness
of a pavement with initial deflections as an index in design. The initial deflection can
be determined by the correlation method or the strength compensation method.
