Effect of dual and new generation wide-base tire assembly on inverted pavements
A B S T R A C T: The conventional flexible pavements have been constructed such that the stiffness of the layer reduces with depth. The crust thickness becomes significantly high for heavy traffic corridors resulting in the consumption of large quantities of construction materials and also increasin...

A B S T R A C T: The conventional flexible pavements have been constructed such that the stiffness of the layer reduces with depth. The crust thickness becomes significantly high for heavy traffic corridors resulting in the consumption of large quantities of construction materials and also increasing environmental pollution. Inverted 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 corridors. The AIL or SAMI is placed between a stiff cement-treated base and asphalt concrete layer to function as crack relief layers. This change in the composition alters the behaviour of inverted pavements compared to the conventional flexible pavements. On the other hand, wide-base tires are being increasingly preferred by trucking industries due to increased fuel economy and cargo capacity.
