| 摘要： | This study was conducted to develop a methodology to incorporate the structural contribution of working platforms, including those constructed with industrial by-products, into the design of flexible pavements. Structural contribution of the working platform was quantified in terms of a structural number or an effective roadbed modulus. Resilient modulus obtained from large-scale model experiments (LSME) conducted on several working platform materials (i.e., crushed stone (referred to as “breaker run”, Grade 2 granular backfill (referred to as Grade 2), foundry slag, foundry sand, and bottom ash) were used in the analysis. Design charts are presented that show the structural number or the roadbed modulus as a function of type of material and thickness of the working platform. |
