Full-scale validation of bio-recycled asphalt mixtures for road pavements

2019

Abstract Recycling of asphalt has become a well-established practice in many countries, however the road pavement industry remains a bulk consumer of extracted raw materials. Novel solutions that find root in circular economy concepts and life-cycle approaches are needed in order to enable optimisation of infrastructure resource efficiency, starting from the design stage and spanning the whole value chain in the construction sector. Itis within this framework that the present study presents a full-scale validation of asphalt mixtures specifically designed to ensure durability of flexible road pavements and at the same time enabling the reuse of reclaimed asphalt pavement (RAP) through the i…

Portable non invasive analyses for Cultural Heritage

2014

The requirements that the scientific analyses for Cultural Heritage must have are: nondestructive and noninvasive, multielemental, sensitive, reliable and sufficiently rapid, able to carry out measurements in situ on objects of all types, and to deduce information practically on-line. Among the techniques that fulfill these requirements we find: multispectral imaging, portable EDXRF, Raman and UV-VIS-NIR spectrometry. In this paper we are going to show some cases in which it will appear clear the necessity of the correct order with which applying the non invasive techniques and what data of each of them it is necessary to understand in situ to obtain the maximum of the subsequent scientific…

RGB Photoelasticity: Review and Improvements

2010

:  This paper considers the main developments of RGB photoelasticity with reference to the maximum measurable retardation. In this paper, a new procedure based on the standard error function evaluated on a subset of the calibration array is also proposed and experimentally tested. The experiments show that the filament lamp makes it possible to find retardations until approximately 4 fringe orders while the fluorescent lamp makes it possible to determine higher fringe orders (12 fringe orders in this paper) owing to the discrete spectrum of the source. The paper shows that, by using the incandescent lamp, the primary limiting factor is the lack of modulation of the R, G and B signals wherea…
