ABSTRACT

Artificial neural network (ANN) was adapted in this research study for the modelling of the shrinkage properties, consistency indices and swelling potentials of expansive clayey soil stabilized using HARHA as chemical additive. RHA is obtained from the milling of rice as an agricultural or industrial waste which encourages the utilization and recycling of solid waste derivatives for engineered infrastructure to offer greater economic and environmental benefit to the construction industry. Varying ratios of HARHA was utilized in treatment of the expansive clayey soil ranging from 0 % to 12 % and the laboratory responses were obtained which provides expert historical data for the ANN model development; with the soil-HARHA replacement ratio and corresponding Atterberg limit responses as the network input variables while the shrinkage, clay activity and swelling characteristics were utilized as the network output parameters. The optimized network architecture for the network based on R-values and MSE performance criteria produced NN 5-9-6 using Levernberg Marquardt training and feed-forward back propagation algorithm in MATLAB toolbox. The developed ANN model’s performance was evaluated using loss function parameter (RMSE) and the computed results is further compared with MLR model results to produce mean coefficient of determination of 98.27 as against 99.99 obtained from the generated ANN model which signifies a better performance in terms of estimation accuracy for the prediction of the expansive clayey soil-HARHA mixture characteristics.
