Relationship between files: Each asphalt mix is represented by four interrelated files: two in Excel (.xlsx) format and two in Dynamic Graph Project (.dgpx) format. The .xlsx files contain processed datasets, calculations, charts, and results that were generated from the .dgpx project files for accessibility and further analysis. The .dgpx files serve as the native project files created using the AASHTOWare Pavement ME® Design software, storing the original graphical configurations, modeling parameters, and simulation outputs. For each mix (Mix 1, Mix 2, Mix 3, . . . Mix 11), the four files correspond as follows: I-15_NB_Mix_[#]_BBR_+_MS.xlsx: Processed results for both BBR and Master Curve analyses. I-15_NB_Mix_[#]_BBR_+_MS.dgpx: Dynamic Graph Project file used to generate plots and rheological results. I-15_NB_Mix_[#].xlsx: Processed Master Curve–only dataset. I-15_NB_Mix_[#].dgpx: Dynamic Graph Project file for Master Curve analysis visualization. Together, these files form a complete dataset package linking experimental BBR data, fitted master curves, and mechanistic-empirical pavement design simulations for each asphalt mix. 3. Additional related data collected that was not included in the current data package: NA 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: The dataset was generated through laboratory testing of eleven asphalt mixtures (seven plant-produced mixtures from Utah, two from Minnesota’s MnROAD cells, and two laboratory-produced mixtures at the University of Utah). Microsoft Excel (Microsoft 365) was used to process raw BBR stiffness data, perform polynomial fitting, extrapolate maximum dynamic modulus (Emax), and construct master curves using standard regression routines. AASHTOWare Pavement ME® Design (v3.5) was used to simulate pavement performance (rutting, fatigue cracking, and thermal cracking) with Level 1 dynamic modulus inputs. Utah Department of Transportation (UDOT) Pavement Performance Database provided field cracking data for Utah mixtures. Data were extracted, reformatted, and combined into a normalized cracking index for comparison with laboratory-derived predictions. 2. Methods for processing the data: The submitted dataset was generated from raw laboratory test results and field performance records. 3. Instrument- or software-specific information needed to interpret the data: The .dgpx files were created using AASHTOWare Pavement ME® Design (version 3.5) and its Dynamic Graph Project module, which stores modeling parameters, regression fits, and graphical configurations. The .xlsx files were generated in Microsoft Excel (Microsoft 365) and include processed and reformatted data extracted from the .dgpx files. This ensures accessibility for users who may not have AASHTOWare software installed. All key numerical outputs and plots (BBR stiffness, master curve fitting, and performance predictions) have been reproduced in the Excel files for transparency and reproducibility. 4. Standards and calibration information, if appropriate: The BBR was calibrated according to the manufacturer’s specifications before testing sequences, ensuring accurate load and deflection measurements. 5. Environmental/experimental conditions: BBR tests were conducted in a temperature-controlled lab (University of Utah) at 0°C to –24°C, with specimens conditioned for 60 minutes before testing. Asphalt mixtures were compacted to 7.0% ± 0.5 air voids using the Superpave Gyratory Compactor. A constant load of 450 g was applied per AASHTO TP 125-16. Field performance data from UDOT reflect natural environmental conditions in Utah. 6. Describe any quality-assurance procedures performed on the data: BBR was calibrated per AASHTO standards, specimen dimensions were verified, and 15 replicates per mixture ensured reliability. Outliers were excluded if outside ±2 SD. Data were cross-checked in Excel and AASHTOWare for consistency. 7.
