The Reflective Cracking in Flexible Pavements [PDF]

open access: yesRomanian Journal of Transport Infrastructure, 2013
Abstract Reflective cracking is a major concern for engineers facing the problem of road maintenance and rehabilitation. The problem appears due to the presence of cracks in the old pavement layers that propagate into the pavement overlay layer when traffic load passes over the cracks and due to the temperature variation.

A Numerical Study on the Crack Propagation of Homogenized Micro-Crack Crushing for Concrete Pavement

open access: yesApplied Sciences, 2022
Homogenized micro-crack crushing is a new method of concrete pavement rehabilitation that makes full use of the bearing capacity of the original concrete pavement, whereby the treated pavement can be directly overlaid with hot mixed asphalt concrete.

Classification of 3-dimensional integrable scalar discrete equations [PDF]

open access: yes, 2007
We classify all integrable 3-dimensional scalar discrete quasilinear equations Q=0 on an elementary cubic cell of the 3-dimensional lattice. An equation Q=0 is called integrable if it may be consistently imposed on all 3-dimensional elementary faces of ...

Observation of nano-indent induced strain fields and dislocation generation in silicon wafers using micro-raman spectroscopy and white beam x-ray topography [PDF]

open access: yes, 2010
In the semiconductor manufacturing industry, wafer handling introduces micro-cracks at the wafer edge. During heat treatment these can produce larger, long-range cracks in the wafer which can cause wafer breakage during manufacture.
