Monitoring deformations of infrastructure networks: A fully automated GIS integration and analysis of InSAR time-series

Ageing stock and extreme weather events pose a threat to the safety of infrastructure networks. In most countries, funding allocated to infrastructure management is insufficient to perform systematic inspections over large transport networks. As a result, early signs of distress can develop unnoticed, potentially leading to catastrophic...

Mad City: Imagination of rap music as an experimental methodological device for the re-imagination of urban space in Los Angeles

The dilemma of race and space is deep entwined in the history of United States. From the slave quarters of plantations in the South to redlining and housing projects, the unjust distribution of space between diff erent ethnic groups has demarcated “otherness” until recent days. Perhaps the most vocal witnesses of the spatial injustice and the...

Effects of crumb rubber size and percentage on degradation reduction of railway ballast

Higher speed, more freight and frequent maintenance increase ballast degradation and reduce the ballast lifespan. To reduce ballast degradation, crumb rubber used as buffering aggregates in ballast bed is relatively unexplored and needs more studies, because using it has the advantage of reusing the waster rubber and absorbing the noises. The...

Ballast degradation: Effect of particle size and shape using Los Angeles Abrasion test and image analysis

Ballast track is the most widely used track for the railway transport, and ballast bed plays a significant role to provide resistances during train operation. Generally, the ballast bed consists of crushed stones. To achieve the mitigation of ballast degradation, the first priority is to describe the degradation development and to study its...

How Los Angeles test could be better adapted to the recycled concrete aggregate

In order to clarify the significance of Los Angeles test when being used with RCAs, three aspects were investigated: the influence of the number of revolutions, the evolution of the full particle size distribution and the distribution of mortar in the fractions after the test. The standard testing procedure for the Los Angeles index requires the...

Los Angeles: The metropolis and five stages of modernity

‘the metropolis and five stages of modernity’ is an explorative research on contemporary ecologies and the historic (re)-emergence of public domain, infrastructure and urban form in Los Angeles
