| Abstract: | The significance of measuring modulus of resilience based on proposed design philosophy which takes impacted and compacted existing cement concrete slab as one of structural layers for overlay design are discussed in this paper By processing lots of bearing plate testing data in situ, the magnitude and value range of modulus of resilience and its trend for existing cement concrete slabs and base course after impact and compaction are got. They can be used for evaluating remains bearing force of the pavements as useful parameters in design of overlay pavement structure |
