Why do you put grit on the road?

Answer 1

There are two reasons: 1) adding grit to the road helps to improve the tyres' grip on the icy surface.

2) the grit contains salt and that lowers the freezing point of water, so it helps prevent ice forming.

Answer 2

In the UK, road grit (finely crushed granite) is often used in very hot weather, when the tar and chipped road surface begins to melt and the tar sticks to vehicles and bicycle tyres. The grit is similar to a cook flouring a board to prevent pastry sticking to the board when it is rolled out.

In winter, rock salt and sand is spread on roads to prevent vehicles skidding on the icy road surface.

Answer 4

Sand and grit are spread on roads in the winter in states that receive snow and ice in the winter. Sand and grit prevents a car from sliding on ice.

Answer 5

Roads are covered in these to give car wheels traction while driving on snow and ice
