Optimization of Continuously Reinforced Concrete Pavement to Truck Platoon Loading

Truck platooning is one of the most recent technologies with a great potential to make road freight safer, cleaner, and more efficient. The automated driving system in truck platooning keeps the trucks in a fixed distance from the edge of the lane creating a channelized traffic. This creates higher accumulation of fatigue damage in the wheel path of the platoon which significantly reduces the service life of pavement. This study investigated several ways to improve the performance of continuously reinforced concrete pavement (CRCP) and extend its longevity to withstand truck platooning traffic. A 3D finite element modeling was implemented to model CRCP and analyze pavement responses under truck platooning and normal traffic. Fatigue analysis was conducted to investigate possible performance improvement of three design considerations. The results indicated that increasing the thickness of concrete slab significantly improves the fatigue performance of pavements under channelized traffic and reduces the difference between the maximum accumulated fatigue damage created by truck platooning and traffic with normal wander. Thus, the negative impact of channelized traffic on fatigue performance of concrete pavements reduces as the thickness of the slab increases. In addition, using larger diameter rebars under the wheel path showed negligible improvement on the fatigue performance of pavements under truck platooning traffic. It was observed that the relative improvement in fatigue performance is highly dependent on the fatigue models used for PCC.
