Materials and technologies for winter road maintenance in Lithuania

Winter season in Lithuania lasts 5-6 months. As in many European and other countries in the world, traditional materials of winter road maintenance are used: NaCl, CaCl2, their mixes or more ecological products manufactured on their basis. On gravel roads or low-volume roads the mixes of NaCl and frictional materials (sand, crushed stone) are used. For maintenance purposes (to reduce slipperiness) a wet salt technology is applied or spreading of chloride- frictional material mixes.
