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

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 ...

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.

Segment-based pavement crack quantification

Automation in Construction, 2019
Abstract Accurate quantitative information of crack length and width is important for assessing the severity level of cracks and making accurate pavement maintenance decisions. Nevertheless, due to the noise and fluctuation at the crack edge of pavement image, itis difficult to precisely determine the edge correspondence of crack that is necessary ...

Cracking Mechanism of Flexible Pavements

Transportation Engineering Journal of ASCE, 1972
THE PAPER DEALS WITH THE CRACKING OF FLEXIBLE PAVEMENTS CAUSED BY SHRINKAGE DUE TO DRYING OF THE SUBGRADE. A CRACKING MECHANISM IN PAVEMENTS IS PROPOSED, BASED ON THE PRINCIPLE THAT CRACKS FIRST APPEAR IN THE SUBGRADE AND ARE AFTERWARDS REFLECTED THROUGH THE ASPHALTIC LAYER.

Fatigue Crack Growth in Pavements

Journal of Transportation Engineering, 2000
A common laboratory fatigue test for life estimation of pavements uses a repeated load flexural device with nonlayered beam specimens. As a result of such factors as traffic wander, and also due to different crack growth rates between such beam specimens and layered media, highway pavements have been found to sustain from 10 to 100 times the number of ...

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.

Sealant Degradation during Crack Sealing of Pavements

Journal of Materials in Civil Engineering, 1998
Application practices of bituminous hot-poured crack sealants, typically used to effect repairs on pavements, were monitored in the field and heating conditions were reproduced in the laboratory. From viscometry, thermogravimetry, and tensile testing measurements, it was found that sealants degrade upon heating at recommended installation temperatures.

Horizontal Cracking and Pavement Distress in Portland Cement Concrete Pavement

Designing, Constructing, Maintaining, and Financing Today's Airport Projects, 2002
This paper describes how severe spalling and half-depth punchout failures associated with horizontal cracks at the mid-depth of the concrete slabs were observed in continuously reinforced concrete pavement (CRCP) in Texas. A study was conducted to identify the causes of those horizontal cracks and their effect on pavement distress.
