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 ...

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.

Rough thin pavement thickness estimation by GPR [PDF]
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009 In civil engineering, usually the methods used to estimate the thickness of thin pavements consider flat interfaces for simplification. In this paper, the roughness of the surfaces is taken into account. First, the amplitudes of the first two echoes from the rough thin pavement are calculated from a rigorous electromagnetic method, the PILE method.

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.

Wavelet Filter Design for Pavement Roughness Analysis
Computer-Aided Civil and Infrastructure Engineering, 2016 Control and characterization of pavement roughness is a major quality assurance requirement. With emerging technologies in real-time monitoring and increasingly stringent requirements to minimize localized roughness features, there is an opportunity to improve upon the traditional quarter-car QC algorithm used to qualify roughness.

Application of Vehicle Mounted Accelerometers to Measure Pavement Roughness [PDF]
International Journal of Distributed Sensor Networks, 2016 To enhance the efficiency of pavement roughness measurement and reduce the cost, an integrated and wireless transfer based measuring system was developed. The proposed system can obtain vehicles status and location data via wireless acceleration sensors and GPS, calculate the international roughness index (IRI) by power spectral density analysis, and ...
