Do You Know About Slippery Roads After A Heatwave?

July 29, 2018

The rain this week could make roads slippery after the heatwave. 


There are two reasons why motorists should slow down and drive with care on roads that are wet after a heatwave. Firstly, during periods of prolonged hot weather the bitumen in asphalt roads becomes more mobile and can sometime ‘bleed’ through to the surface. This reduces the texture depth and wet skidding resistance. In extreme conditions, like those experienced this summer, councils will apply grit to the road surface to increase its skid resistance.


Secondly, dry roads often have a build-up of rubber and oil particles. When it rains these substances can mix with water and create a greasy layer that can become very slippery.


Wet roads after a prolonged hot, dry period can become slippery. In addition to ensuring that their tyres are in good condition and properly inflated, motorists should slow down and drive with care.


Stay safe on the bike!
