Why are UK roads not concrete?

In the UK most, if not all concrete surfaces will be 30-40 years old, which is probably why they are so bumpy, noisy, poorly-drained and generally unsightly. However one big disadvantage for concrete is that low sun can make it difficult to see the road markings. It does make an awful noise when you drive on it though.

Why are UK roads so rough?

The UK has a climate that is often cold and wet, especially during the winter months. This can be tough on road surfaces, as water can seep into cracks in the road and then freeze, which causes it to expand and crack further. The repeated cycle of freezing and thawing can lead to potholes forming.

What are China roads made of?

They were consequently prone to surface fissuring and uneven drainage. The Chinese roads, on the other hand, were more akin to modern highways, being thinner and more elastic. They were built with a rubble sub-base onto which a layer of finely tamped gravel was added to produce a 'water- bound macadam'.

What are Australian roads made of?

A major highway is typically one layer of gravel followed by four layers of asphalt or two layers of concrete. Other highways and secondary roads have three layers of gravel followed by two layers of sprayed bitumen. This can vary according to the type of ground and the expected traffic load.

Do they salt the roads in the UK?

Salt is more than something to sprinkle on to your fish and chips, this common household ingredient keeps England's roads moving when temperatures plunge.

British roads are made from asphalt, but some are built from concrete. The Road Surface Treatments Association said the surface can begin to melt as it hits 50C. This can happen even when the air temperature drops as low as 20C at the end of a day, because the road surface absorbs heat during the heat of the day.
