Resilient modulus prediction of RAP using the Contact Dynamics Method

open access: yesTransportation Geotechnics, 2020
Abstract The Optimal Recycling of Reclaimed Asphalts in low-traffic Pavements (ORRAP) project concerns a cold recycling of 100% Reclaimed Asphalt Pavement (RAP) without binder addition, in base and subbase layers of low-traffic pavements. The mastic coating of aggregates induces a viscoelastic behaviour and changes the resilient modulus with ...

Dynamic Parameters and Hysteresis Loop Characteristics of Frozen Silt Clay under Different Cyclic Stress Paths

open access: yesAdvances in Materials Science and Engineering, 2021
In cold regions, the long-term stability of engineering facilities is unavoidably influenced by the negative temperature, freeze-thaw process, dry-wet process, and dynamic loading conditions induced by earthquakes and traffic loads.

Influence of Humidity State on Dynamic Resilient Modulus of Subgrade Soils: Considering Repeated Wetting‐Drying Cycles [PDF]

open access: yesAdvances in Materials Science and Engineering, 2021
The service performance of subgrade depends on the dynamic resilient modulus (MR) of subgrade soils. Meanwhile, due to complicated conditions such as rainfall infiltration, high temperature evaporation, and groundwater level fluctuations, it can be safely said that the humidity state and repeated wetting‐drying (WD) cycles affect the MR of subgrade ...
