| Abstract | The capacity of an Asphalt Pavement to resist loads depends on its temperature due to its viscoelasticity. Because of this, measurements gathered from field tests vary due to different temperatures experienced by the pavement. Temperature correction procedures are developed by different countries to properly address this problem. However, in the Philippine setting, such temperature correction procedures are yet to be established. A reference temperature should also be set to standardize FWD measurements, however, no reference temperature is yet to be established for perusal in the Philippines. The study aimed to bridge this gap by conducting an experiment that collected temperatures at three (3) set depths; pavement surface, mid depth, and third depth on a test pavement located at the Ninoy Aquino International Airport (NAIA). Using these measurements, a temperature prediction model based on polynomial regression analysis and elastic net regularization technique was developed. The application of the elastic net regularization technique minimized highly correlated pavement temperature factors to simplify model inputs and be used with ease during FWD tests. The model performed better than existing models with an r-squared value of 0.932 and 0.864 at mid and third depths respectively with errors lower than existing models in comparison. It was recommended to utilize the temperature prediction model to develop standard procedures in using the Falling Weight Deflectometer (FWD) in monitoring the structural capacity of pavements and to establish a local reference temperature for temperature correction procedure. |
