They are used to increase the road friction and prevent vehicle skidding on the rainy and snowy day and on the sharp bend parts. Some other accident-prone areas of Leiyi expressways were facilitated with such kind of non-slip surface. In addition, some horizontal deceleration strips were set in these sections to keep the safety when driving there. Some wheel gear road marking were facilitated in many sections of Leiyi expressway.
