Recognition of pavement surface crack

2010 Sixth International Conference on Natural Computation, 2010
This article describes the pavement crack detection system architecture shows the hardware options and rationale, as well as the system works. This paper uses the median of the road image de-noising filter. In contrast to edge detection sobel and prewitt operator to verify the validity and advantages of the sobel.

Investigating Pavement Cracking

Transportation Research Record: Journal of the Transportation Research Board, 2006
Because of the combined practical and theoretical interest in pavement performance modeling, much research has concentrated on this area during the past few years. The objectives of this study are, first, to cluster pavement distress data into homogeneous groups depending on the extent of distress and, second, to identify and assess the influence of a ...

Automatic inspection of pavement cracking distress

SPIE Proceedings, 2005
We present an image processing algorithm customized for high-speed, real-time inspection of pavement cracking. In the algorithm, a pavement image is divided into grid cells of 8×8 pixels, and each cell is classified as a noncrack or crack cell using the grayscale information of the border pixels. Whether a crack cell can be regarded as a basic element (

Accelerated pavement testing and modeling of reflective cracking in pavements

Engineering Failure Analysis, 2007
Abstract In the field of reflective cracking initiation and propagation in pavement structures, an Accelerated Pavement Testing (APT) has been developed. The numerical method is also supported. Numerical results obtained by calculations made with the finite element CESAR-LCPC software are then compared with the experimental data.

Prevention of Cracks in Pavements. Achievements and Open Questions

Road Materials and Pavement Design, 2005
RILEM Technical Committees have been active since more than 15 years on the prevention of Reflective Cracking in Pavements. Papers published over that period in the proceedings of four RILEM international conferences devoted to this topic constitute an unmatched source of information for highway engineers.

Prediction of Pavement Crack Initiation from In-Service Pavements

Transportation Research Record: Journal of the Transportation Research Board, 2005
It is widely accepted that the success of pavement management systems largely depends on the quality of the deterioration models embedded in their structure. As such, much research has concentrated on developing a large array of approaches to model and predict pavement distress and deterioration.

Cracking in Concrete Pavement

1979
Cracking of portland cement concrete pavements is a common, even expected, occurrence. To minimize potentially detrimental effects, it is necessary to understand mechanisms that might be used to explain such behavior so that measures may be developed and implemented to control the occurrence of such cracking. Several "theories" are discussed that might

Pavement Cracking

2008
Internationally, much attention is given to causes, prevention, and rehabilitation of cracking in concrete, flexible, and composite pavements. The Sixth RILEMInternational Conference on Cracking in Pavements (Chicago, June 16-18, 2008) provided a forum for discussion of recent developments and research results.This book is a collection of papers ...
