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
