1 lip 2024 · Lower temperatures significantly expedite the phase transition from water vapor to ice, hastening the vertical growth of frost layers on road surfaces. Air temperature and velocity are found to have a nuanced effect on frost formation, with higher temperatures initially promoting rapid accumulation.
18 wrz 2017 · Higher air temperatures cause roadway surfaces to deteriorate more rapidly. Now research suggests that adapting design and material selection procedures to use future climate information can...
Pioneered during the 1970s, thermal mapping is a technique used to measure the spatial variation of nocturnal road surface temperature (RST) around a road network (Thornes 1991). RST is measured at a set resolution from a mobile platform by using an infrared thermometer focused on the road surface.
29 gru 2006 · Used to predict icy stretches of road during winter nights, thermal mapping is the measurement and visualisation of road surface temperatures for road ice prediction. From its development in the 1970s, the accuracy of thermal mapping has been subject to numerous systematic and random errors.
1 gru 2012 · Road ice can form in a variety of ways, the two most common being a wet road surface cooling below freezing point or ice crystals being deposited on the road due to hoar frost. The freezing point is 0 °C degrees for clean water, but can be lowered by adding a de-icing agent.
