Pavement Macrotexture Parameters: Data, Supplementary Materials, and Code for Parameter Computation

This data repository accompanies a study focused on the quantification and characterization of 86 scale-dependent spatial macrotexture parameters of pavement surfaces. Its primary purpose is to promote transparency and reproducibility while enabling researchers to replicate, enhance, or extend the work conducted by Dr. Sabillon-Orellana. The ZIP folder includes the following files: • Readme.txt: A brief guide to understanding the two Excel files used in the study. • D1_Processed_Profiles.xlsx: Contains the transverse pavement profiles after being processed using the Sabillon-Orellana Filtering Algorithm (SOFA). • D2_Computed_Parameters.xlsx: Includes the computed values of all 86 texture parameters for each profile prior to aggregation. • Code_Pavement_Parameters.R: An R script that provides the source code for all functions used to compute the complete set of pavement texture parameters. • Supplementary Material A – Parameter Table.docx: Provides a list of the 86 parameters, their abbreviations as used in the study, and their corresponding source documents. • Supplementary Material B – Texture Parameters.docx: Contains equations, brief descriptions, and practical applications for each parameter. All data were collected by the contributors and represent a subset of a larger dataset of texture measurements and pavement images gathered under TxDOT Project 0-7139: Determination of Pavement Surface Type. For access to the raw pavement profiles, further details on the processing algorithm, or additional information about the study, please contact Dr. Sabillon-Orellana.
