Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 21, Page 3385-3402, 29 August 2025.ABSTRACT Although estimating the International Roughness Index (IRI) is crucial, previous studies have faced challenges in addressing IRI prediction for asphalt concrete (AC) overlays on Portland cement concrete (PCC) pavements. This study introduces machine learning to predict the IRI of AC overlays on PCC pavements, focusing on incorporating pre ...

Numerical Method of Flexible Pavement considering Moisture and Stress Sensitivity of Subgrade Soils
Advances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019 Weaknesses of the subgrade structure induce the asphalt surface diseases and shorten the service life of flexible pavement. However, the resilient modulus (Mr) of subgrade soils is difficult to be evaluated directly since the subgrade is hidden and covered by the granular or asphalt layer.

Prediction Model for Asphalt Pavement Temperature in High‐Temperature Season in Beijing
Advances in Civil Engineering, Volume 2018, Issue 1, 2018., 2018 Asphalt pavement temperatures greatly influence on the bearing capacity and performance, especially in high‐temperature season. The variation rules of pavement temperatures under the high‐temperature range affect the design and maintenance management of the asphalt pavement, as well as the accurate prediction for pavement temperatures. However, asphalt
