Thermochromism applied to Transportation Engineering: asphalt roads and paints

چکیده
Abstract Thermochromic materials change their optical response to temperature reversibly. This study explores the application of thermochromism road engineering, which is still incipient in this area, from two perspectives. The first one about development functionalized markings (FRM) working as thermochromic sensors alert presence ice on and, way, improve safety. second concerns functionalization asphalt pavements for reversible color at high temperatures reduce energy absorption form heat mitigate Urban Heat Islands (UHI) effect. For FRM, thermocapsules were added into acrylic ink, applied an AC10 mixture, submitted and low temperatures, visually characterized. aiming UHI reduction, solutions (TS) containing thermocapsules, dye, resin superficially sprayed AC10, Quick Ultraviolet Accelerated Weathering Test (QUV) was performed with subsequent Colorimetry Analysis, where coordinates defined by Comissione Internationale de l' Éclairage (CIE) measured. results show that it possible functionalize marks work a sensor. Also, property can be improved synthesizing or using TT closer water melting point. also indicate pavement surface spraying TS points out higher luminosity terms coordinate, intended mitigation absorption, consequently mitigating UHI.

The use of a Rotary Asphalt Broom to Groom Aggregate Forest Roads
Due to the dispersed nature of forestry operations in much of the world, only a subset of a given forest road network are used in any year. Specifically, spur roads are generally only used when harvesting operations are adjacent to roadways; otherwise, they remain unused or only have infrequent administrative traffic. During these periods of light use, a substantial amount of organic litter may...

In this paper we introduce the core results of the project on visualisation and analysis of data collected from the vertical transport facilities. The aim of the project was to provide better user experience as well as to help building maintenance staff to increase productivity of their work. We elaborated a web-based system for vertical transportation, to cover the needs of (1) staff working o...
متن کاملIdentification Effect of Nanoclay on Engineering Properties of Asphalt Mixtures
Nanoclays are new generation of processed clays of interest in a wide range of high performance composites. In other words, nanoclay is defined as a clay that can be modified to make the clay complexes compatible with organic monomers and polymers. Here, it can be said that the polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number ...
