Summary
This study introduces a new method for pavement crack analysis using historical data. It accurately detects new cracks by comparing current images with past ones, improving pavement management systems.
Area of Science:
- Civil Engineering
- Computer Vision
- Materials Science
Background:
- Pavement crack analysis is vital for effective Pavement Management Systems (PMS).
- Accurate crack detection and growth monitoring are essential for infrastructure maintenance.
- Existing methods may lack efficiency or precision in automated analysis.
Purpose of the Study:
- To develop a novel, automated approach for pavement crack analysis using historical data.
- To enhance the accuracy and efficiency of crack detection and growth monitoring.
- To provide a robust solution for modern Pavement Management Systems.
Main Methods:
- A multi-scale localization technique (GPS-based, image-level, metric) was employed for image correspondence.
- Historical crack pixels were mapped to query images as seed points for analysis.
- The Region Growing Method (RGM) was applied for detecting newly grown cracks.
Main Results:
- The proposed method demonstrated effective mapping of historical crack data.
- Newly grown cracks were successfully detected using the RGM with mapped seed points.
- An F-measure of 88.9% was achieved for crack growth detection in real-world pavement images.

01:20Microcracking in Concrete
331
Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...

01:28Types of Non-structural Cracks in Concrete
385
Non-structural cracks are primarily of three types: plastic, early-age thermal, and drying shrinkage cracks. Plastic cracks are further classified into plastic shrinkage cracks and plastic settlement cracks.
Plastic shrinkage cracks typically form within hours after the concrete is poured. The concrete's surface dries faster than the bottom, creating tensile stress that the still-plastic concrete cannot withstand, leading to diagonal or randomly patterned cracks on the concrete surface.

01:28Design Example: Joints in Concrete Pavements
387
Concrete pavement joints are essential for maintaining the structural integrity and longevity of pavement by controlling where and how the pavement cracks. These joints can be categorized based on their functions, such as contraction or control joints, construction joints, isolation joints, and expansion joints.
Contraction joints are typically formed by sawing a groove into the concrete shortly after it has hardened. This creates a weakened vertical plane, deliberately encouraging cracking at...

01:22Creep in Concrete
892
Creep refers to the time-dependent increase in strain under a sustained load, excluding other time-dependent deformations associated with shrinkage, swelling, and thermal expansion in concrete. The primary mechanism behind creep involves the loss of physically adsorbed water from the calcium silicate hydrate within the hydrated cement paste. This process is further exacerbated by concrete's non-linear stress-strain relationship, microcrack development in the interfacial transition zone, and...

01:16Tensile Strength Considerations of Concrete
362
Considering the tensile strength of concrete involves recognizing that the theoretical strength of cement paste can be up to a thousand times higher than what is observed in practical applications. This significant discrepancy is largely attributed to the presence of microscopic cracks within the concrete. These cracks tend to amplify stress at their tips when a load is applied, a phenomenon explained by Griffith's theory of brittle fracture.

01:13Mortar Joint Deterioration in Masonry
251
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.
