The resilient modulus (MR) of subgrade soils is usually used to characterize the stiffness and a crucial parameter in pavement design. In order determine compacted quickly accurately, an optimized artificial neural network (ANN) approach based on multi-population genetic algorithm (MPGA) was proposed this study. MPGA overcomes problems traditional ANN such as low efficiency, local optimum over-...

The subgrade layer is the lowest pavement layer, which carries loads transferred from upper layers. Different researchers have studied resilient modulus (Mr) of different soils for fine-grained and coarse-grained soil types. layer's response mechanism was found to be those fine coarse materials, it vital improving performance life constructed over it. parameters related that can affect include ...
