Mar 25, 2021· The performance of asphalt concrete pavements (ACP) is greatly related to the rate of rutting. Stone dust is mostly used as a filler in ACP. Bagasse ash being cementitious in nature, and costless waste can also be used as a filler. The overall aim is to select a suitable filler for better performance of asphalt concrete pavements. The effectiveness of locally available bagasse ash is …


[PDF] EFFECT OF LAYER SLIPPAGE ON PERFORMANCE OF ASPHALT ...

Stresses and strains that result from aircraft loading in an asphalt-concrete pavement section were computed by layered elastic theory. A fatigue model was used to estimate the life of the pavement. Variations in interlayer slippage, layer thickness, asphalt stiffness, and pavement loading were shown to affect the life of the pavement. Layer slippage generates large tensile strains at the ...
