主　　题：Aggregate interlayer Inverted pavement Shear strain Stress absorbing membrane interlayer Wide-base tire 

摘      要：The conventional flexible pavements have been constructed such that the stiffness of the layer reduces with *** crust thickness becomes significantly high for heavy traffic corridors resulting in the consumption of large quantities of construction materials and also increasing environmental *** pavements with the aggregate interlayer(AIL)or stress absorbing membrane interlayer(SAMI)are considered to be one of the alternatives for thick conventional flexible pavements for heavy traffic *** AIL or SAMI is placed between a stiff cement-treated base and asphalt concrete layer to function as crack relief *** change in the composition alters the behaviour of inverted pavements compared to the conventional flexible *** the other hand,wide-base tires are being increasingly preferred by trucking industries due to increased fuel economy and cargo ***,the effect of wide-base tires on the performance of inverted pavements is yet to be *** this study,the 3D finite element(FE)models of inverted pavements considering different crack relief layers were developed,and load from dual-wheel and wide-base tires were *** stress-strain evolution in the various layers of inverted pavements was investigated and discussed in this *** results indicated the higher stress and strains due to wide base tires compared to the dual-wheel ***,pavement with SAMI was found to result in lower stress and strains in the asphalt concrete layer compared to AIL pavements.
