Research: Longitudinally Textured PCC Pavement Most Energy-Efficient Surface

As tire manufacturers and pavement researchers are searching for new ways to improve fuel economy, conserve fossil fuels and improve sustainable driving, fuel economy is a critical consideration. Rolling resistance results in small amounts of continual energy loss, which in turn becomes fuel waste. Decreasing rolling resistance can save on a vehicle's fuel consumption, so researchers have focused on ways to control the distortion and compression of tires and pavement. A 3D numerical multiscale model was developed to analyze the effect of pavement macrotexture on tires, with predictions made for real-life surfaces based on laboratory testing. Results showed that longitudinally oriented concrete surfaces were the most environmentally friendly (least energy loss) texture and may also result in lower noise. These textures include diamond saw-cut, achieved by conventional diamond grinding, longitudinal safety grooving and the Next Generation Concrete Surface (NGCS).
