description: Data and Code for - <b>Surrogate Modelling of Surface Roughness for Asphalt Pavements Using Artificial Neural Networks: A Mechanistic-Empirical Approach</b><b>Introduction</b>These data and code accompany the paper titled "Surrogate Modelling of Surface Roughness for Asphalt Pavements Using Artificial Neural Networks: A Mechanistic-Empirical Approach" by: Haoran Li, Hessam AzariJafari, Randolph Kirchain, João Santos, and Lev Khazanovich. It was published by the International Journal of Pavement Engineering (IJPE).Cite the paper as: Haoran Li, Hessam AzariJafari, Randolph Kirchain, João Santos &amp; Lev Khazanovich (2024) Surrogate modelling of surface roughness for asphalt pavements using artificial neural networks: a mechanistic-empirical approach, International Journal of Pavement Engineering, 25:1, 2434909, DOI: 10.1080/10298436.2024.2434909The appended folders and files provide the data and code generated and used to analyze the results as described in the study.The following sections explain the structure and content of these files.<b>Data and Code Folder(s) or file(s) and how to use the code or data:</b>"<b>1_Sensitivity Analysis</b>": Contains the data obtained from Pavement ME in performing global sensitivity analysis (GSA). Please run "Paper_Sensitivity Analysis_PieChart.ipynb" to visualize the sensitivity analysis results and reproduce Figure 1 (a) and (b)."<b>Pavement ME Damage Database</b>": Includes pavement damage databases generated from Pavement ME simulations using the novel Scalable Adaptive Sampling method [U.S. Pat. App. No. PCT/US24/10695 (WO2024151535A1)]. For further details on the adaptive sampling and iterative ANN training process, interested readers can refer to a recent publication (https://doi.org/10.1016/j.rineng.2024.102483). These databases supported the development and validation of surrogate ANN models, specifically Model I and Model II, respectively.<b>Reference:</b> Li, H., Sen, S., &amp; Khazanovich, L. (2024).

Please run "Model I Performance Validation.py" to assess its performance in IRI prediction and to reproduce Figure 6 (needs "Pavement ME Damage Database" folder)."<b>3_Model II</b>": Contains ANN models in consisting Model II. Please run "Model II Performance Validation.py" to assess its performance in IRI prediction and to reproduce Figure 7 (needs "Pavement ME Damage Database" folder)."<b>4_Model I vs. Model II</b>": Compare the performance of Model I and Model II in IRI predictions. Please run "Model I vs Model II Performance Validation.py" to compare the performance between Model I and Model II and also to reproduce Figure 8."<b>5_Validation of Model I and II vs. Pavement ME</b>": Additional validation of Model I and Model II using Pavement ME and sensitivity analysis. Please run "ANN vs Pavement ME IRI_MA Sensitivity Analysis_ALL_IRI_SI.py" to assess the performance of Model I and Model II validated by Pavement ME simulations for the same projects. Also reproduce Figure 9."<b>6_AC thickness design application using Model II</b>": Apply Model II for asphalt pavement design practice following MEPDG framework. Please run "AC thickness design with Model II.py" to perform a sample AC thickness design using Model II for Boston, MA and Miami, FL and reproduce Figure 10.<b>Disclaimer</b>The code and data provided in this appendix are made available upon reasonable request from the readers to the corresponding author and under the condition that they are used for academic and research purposes only.
