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.

An alternative approach to pavement roughness evaluation
International Journal of Pavement Engineering, 2008Although structural capacity seems to be the major concern of many pavement engineers, road users primarily judge the quality of a road based on its roughness or ride quality. Several parameters influence the ride quality of pavements as felt by the road users.

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.

Based on the results of recent research, it is possible to develop performance specifications for a simple instrument that would measure profile-type roughness in only one wheelpath—instead of two, as in the profilometer—and which would compute a roughness index that is as highly correlated with pavement rideability measurements as the roughness ...

Pavement roughness measurement based on structure light
SPIE Proceedings, 2008Pavement roughness is an important index to reflect the quality of pavement. To improve the efficiency of pavement roughness measurement, a novel pavement roughness measurement system based on structured light vision inspection is proposed in this paper.

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.

Reproduction Method of Random Pavement Roughness in Laboratory
International Conference on Transportation Engineering 2009, 2009This article presents a study of random pavement roughness reproduction method in a laboratory. At a certainty velocity, with Partial Wave Adding, road power spectral density (PSD) was reconstructed to obtain road surface roughness in time domain and this signal then acted as the required recurrent target signal; then, white noise as input was used to ...
