Microwave Current Imaging in Passive HTS Components by Low-Temperature Laser Scanning Microscopy (LTLSM) [PDF]

open access: yes, 2004
We have used the LTLSM technique for a spatially resolved investigation of the microwave transport properties, nonlinearities and material inhomogeneities in an operating coplanar waveguide YBa_2Cu_3O_{7-\delta} (YBCO) microwave resonator on an LaAlO_3 ...

Non-destructive modulus testing and performance evaluation for asphalt pavement reflective cracking mitigation treatments

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2018
Reflective cracking is a common type of pavement distress, which manifests as cracks in an underlying layer propagating through to the surface of a pavement structure.

The teacher as action researcher : Using technology to capture pedagogic form [PDF]

open access: yes, 2008
The paper argues that we make best use of learning technologies if we begin with an understanding of educational problems, and use this analysis to target the solutions we should be demanding from technology.

Discrete element simulation of crack resistance of asphalt pavement with geotextile reinforced graded gravel base [PDF]

open access: yesAIP Advances
To address reflective cracking in semi-rigid base asphalt pavements, conventional graded gravel transition layers are found to cause anisotropy errors in finite element simulations and be prone to plastic deformation; therefore, this study proposes a ...

Evaluation of Asphalt Overlay Properties on Reflection Cracking Behavior of Composite Pavement Using Finite Element Modeling [PDF]

open access: yesJES: Journal of Engineering Sciences
Reflective cracking poses a significant challenge to the performance and durability of Hot-Mix Asphalt (HMA) overlays, particularly when applied over deteriorated Joint Plain Concrete (JPC) pavements.

Reflective cracking behavior for traffic and temperature effects [PDF]

open access: yes, 2008
This paper presents a study on the influence of the effects of temperature variations, in comparison with traffic effects, on the reflective cracking overlay behavior. It is intended to contribute to the improvement of the pavement overlay design methods which consider reflective cracking as one among distress criteria.

Experimental Evaluation of Engineered Cementitious Composites as Reflective Crack Control Interlayer for Composite Pavements [PDF]

open access: yesMATEC Web of Conferences, 2019
Reflective cracking at transverse joints is considered as a predominant distress in composite pavements. Various interlayers have been used previously to prevent or retard reflective cracking.

Influence of different paving geosynthetics on crack growth phases and strain behavior in asphalt overlays [PDF]

open access: yesE3S Web of Conferences
This study aimed to assess the impact of different paving geosynthetics on crack propagation and the mitigation of reflective cracking in asphalt mixtures based on four-point bending tests combined with Digital Image Correlation (DIC).
