Roughness-Induced Pavement–Vehicle Interactions [PDF]
Transportation Research Record: Journal of the Transportation Research Board, 2015 Pavement roughness affects rolling resistance and thus vehicle fuel consumption. When a vehicle travels at constant speed on an uneven road surface, the mechanical work dissipated in the vehicle's suspension system is compensated by vehicle engine power and results in excess fuel consumption. This dissipation depends on both road roughness and vehicle

Assessment of Risky Cornering on a Horizontal Road Curve by Improving Vehicle Suspension Performance
The Baltic Journal of Road and Bridge Engineering, 2021 Vehicle stability during cornering on horizontal road curves is a risky stage of travel because of additional factors acting. The main stability factor is centrifugal force, which depends on road curve sharpness and is very sensitive to driving speed ...

Sustainability, 2022 Good road quality is an indicator of urban progress. In August 1998, the New Taipei City government implemented the “Road Leveling Project” on roads within its jurisdiction to improve the quality of public transportation. This paper aimed to analyze the International Roughness Index (IRI) of 152 asphalt concrete pavement sections in New Taipei City ...

Effects of Pavement Roughness on Rigid Pavement Stress
Journal of Mechanics, 2011 ABSTRACTPavement roughness causes pavement stress fluctuation along the road. However, the dynamic effects were not taken into account in most pavement design and studies. To investigate the influences of roadway roughness on pavement stresses, this study developed a coupled system consisting of a quarter-car model and an equivalent lump pavement model.
