In Germany pre-wetted spreading is used as a standard method in winter maintenance since many years. Beginning with the year 2008 first tests were made with spreading of liquid brine. In the last years this method has become used more and more, and there were made many experiences with this. Based on these experiences and on different research projects new there was developed a new guideline for liquid [...]

Winter road maintenance (WM) ensures accessibility and road safety during winter weather events. Depending on the weather conditions and winter maintenance strategy, the skid resistance of the road surface and thus the road safety changes dynamically over time. The key challenge is to accurately predict weather developments and road conditions with and without WM to determine the optimal strategy [...]

The incidence of winter road icing significantly hampers transportation efficiency and poses a substantial risk to traffic safety especially in South China where the frozen period is not very long and the cars seldom use snow tyres especially on the bridge surfaces where temperature is lower than normal pavements. The prevention of ice forming is critical in winter maintenance. Consequently, the acquisition [...]

Niigata Prefecture in Japan is one of the country's areas with the heaviest snowfall. Highway administrators in such regions are required to maintain safe and stable lanes during winter. To ensure this, two main operations are conducted: mechanical snow removal and anti-freeze spraying. Snow removal involves clearing snow from the road surface and moving it to the shoulder, causing snow to accumulate [...]

This report presents a thermal mapping analysis conducted on the Kita-Kobe Route of the Hanshin Expressway to identify areas particularly prone to freezing. The study aims to address issues related to road freezing and the frequent use of deicing agents by identifying the most effective locations for installing road heating systems. Over two winter periods in 2021 and 2022, a study was conducted using [...]

According to the guidelines in Austria highways and motorways had to be projected with a maximum longitudinal slope of 6 per cent to ensure a homogeneous traffic flow and avoid problems in winter maintenance. Although most routes have a maximum longitudinal slope of 4 percent there are two routes with a 6 per cent longitudinal slope (A13 Brenner and A 21 Steinhäusl & Gießhübl) with periodic closures [...]
