Operation Methods in winter

Reference number
Coordinator Stockholms Stad - Trafikontoret
Funding from Vinnova SEK 300 000
Project duration December 2016 - April 2017
Status Completed

Purpose and goal

The goal of the project was to design a plow blade that can handle the unevenities of the city´s winter roadway lane network. As well as finding the right mixture of salt solutions to know which mixture gives the best effect based on weather conditions. A split plow blade has been tested and three different mixtures of saline solutions.

Expected effects and result

The plow blade was divided in order to flex and handle the unevenness of the walkway, but the plow blade was not as powerful as desired. After performing tests, adjustments were made to the plow blade. Some of the adjustments he also tested when the snow was left. But the last test did not take place before the snow disappeared. At the same time, the various saline mixtures have been tested in the Vti:s laboratory environment to determine the effects of friction on different conditions in temperature. So far achieved results, we will continue with our development

Planned approach and implementation

Together with machine manufacturers, contractors and the office, perform a test of dividing a plow leaf into several sections to handle the unevenities on the city´s lanes. Coordinate test runs by partly the plow blade and different types of anti-slip solutions. Tests of solutions have been carried out in laboratory environments by scientists at Vti. The experience gained so far will be carried out by the office for future trial and further development
