Analysis of Pavement Roughness
1961In earlier progress reports dealing with the development of triaxial acceleration analysis as applied to the evaluation of pavement riding qualities, of which this report is a continuation, riding comfort or discomfort was emphasized. The accelerations monitored then were evaluated in terms of g's per sec., or "jerk" which is considered by some ...

Effect of Pavement Roughness on User Costs
Transportation Research Record: Journal of the Transportation Research Board, 2012After the construction of a pavement system, deterioration occurs because of traffic loading and weathering action and results in the formation of various types of distresses and an increase in pavement roughness. “Roughness” can be defined as irregularities of pavement surface that affect driver safety and increase user costs, including fuel ...

Pavement Roughness Data Collection and Utilization
Transportation Research Record: Journal of the Transportation Research Board, 1999The Florida Department of Transportation (FDOT) is in the process of evaluating the protocols for collecting and analyzing roughness data. As part of that evaluation, a nationwide survey was performed to identify the trends and practices of various departments of transportation with regard to roughness data collection and analysis.

Influence of Pavement Roughness on Tire Noise
Noise Control and Acoustics, 1999Abstract In this study, the influence of the levels of pavement roughness on tire noise is examined using Nearfield Acoustical Holography (NAH) to measure noise from single tires mounted on a two-wheel trailer towed over different types of pavements.

Definition and measurement of pavement surface roughness
Wear, 1979Abstract Pavement roughness is divided into three scales; roughness, macrotexture and microtexture. All three are surface irregularities of random nature. The dividing lines between them are based on functional considerations such as traffic safety and ride quality.

Impact of subgrade soils on pavement roughness
Canadian Geotechnical Journal, 2016To highlight the impact of subgrade soil variability on the pseudo-profile and roughness at the end of road construction, a research program has been carried out at the Laboratoire sur les chaussées et matériaux bitumineux at École de technologie supérieure (ÉTS).

Spectral Analysis of Highway Pavement Roughness
Journal of Transportation Engineering, 1991This paper reports new findings in the spectral analysis of pavement roughness. Elevation profiles of federal and interstate highways were measured with a profilometer, and spectral analysis was used to compute power spectral densities for the longitudinal elevation of pavements.

Roughness deterioration models for unsealed road pavements and their use in pavement management
International Journal of Pavement Engineering, 2018The present study aims to review the efficacy of three widely used roughness prediction models (Highway Development Model/HDM-4, Australian and South African) in the determination of blading frequencies to control roughness in the management of unsealed roads.

Dynamics analysis of a missile vehicle considering the pavement roughness
2017 IEEE International Conference on Cybernetics and Intelligent Systems (CIS) and IEEE Conference on Robotics, Automation and Mechatronics (RAM), 2017In order to analyze the acceleration response of the connecting bolts on missiles during the missile vehicle maneuvering, a method to simulate the roughness of pavements via the power spectral density of pavements is proposed according to GB/T 7031–2005. A dynamical model of the missile vehicle is built by using "Magic Formula" and Lagrangian dynamics.

Evaluation of the Effect of Pavement Roughness on Skid Resistance
Journal of Transportation Engineering, 2010Roughness of a pavement surface is commonly correlated to its serviceability. On the other hand, on many occasions, investigators have attributed pavement roughness to inadequate skid resistance (friction) as well. However, current pavement friction evaluation and standardization models have yet to incorporate effects of pavement roughness.
