Page 18, 4.1 Salting, add:
"If it is rain, changing with clearing and temperature that give rise to slippery roads, salting continues (9 grams of salt per m2) until the situation is under control.
Page 30, 4.2. Call for salting
"Call have to be done, at least 4 hours before a snowstorm or slippery roads are expected."
"Call for salting, have to be done in time, so all roads are salted before the risk of slippery roads occur. If the call is when it is raining, you have to salt again on the part of the route where it was heavy rain."
" 2 -20 30 29" -> "24 -20 30 29"
Page 35, 6. Traffic accidents with slippery roads
"Based on this database is calculated, that we have to expect accidents with slippery roads :
1 accident on a route with brine spread with nozzles.
2 accidents on a route with salt spread as pre wetted (or dry) salt.
3 accidents on a route with salt spread of a combi spreader (brine, pre wetted or dry
The numbers are annually on 100 km preventive salted road in a normal Danish winter."
"Based on this database is in january 2018 counted, how many slippery roads accidents have been on big 2 lane roads on Funen in the winters 2014 to 2017.
The results are for every winter for every 100 km 2 lane road :
1 slippery road accident when spreading salt as brine with nozzles
2½ slippery road accident when spreading salt as dry or prewettet salt on highway
4 slippery road accident when spreading salt with kombispreader on motorway. On the motorway 8% of all accidents in winter, were with slippery roads. On other highways only 5% of all accidents in winter, were with slippery roads"
