Abstract: Snow falling on roads is rapidly compacted into a hard crust which is difficult to remove, and which may become slippery at temperatures near melting. To avoid this, chemicals are often spread in a measure called anticompaction ...

Abstract: Slippery road surfaces are a threat to traffic safety, especially in winter when snow falling on roads forms a hard crust that is extremely difficult to remove. To prevent this hard crust formation, salt is applied to ...

Abstract: Anti-icing chemicals are used during hoar frost situations to avoid slippery road conditions. During hoar frost situations, humidity is transported from the air to the road surface. This leads to continuous dilution of the ...

Abstract: Hoarfrost on roadways and bridges can cause slippery and dangerous conditions for motorists. To reduce the costs and environmental impact of countermeasures, road authorities wish to optimize their winter maintenance ...

Abstract: This study measures the spectral reflectance from snow with known liquid water content (LWC) in a climate chamber using two optical sensors, a near-infrared (NIR) spectrometer and a Road eye sensor. The spectrometer measures ...
