If rubber wears from our tyres when we drive, why doesn't the road get bigger?
Answers:
Ducks fly down onto the road in the middle of the night and lick the road clean of rubber. That is where rubber ducks come from
It is heated by the pressure and heat of the friction and disappears..
Because other vehicles pick the rubber up an shed it on the road side.
Look at a race track after a race meeting, there will be rubber "marbles" all round the corners in the hardest breaking areas.
This is the excess rubber picked up by hot tyres.
Initially it would go onto the road, along with all the other car by-products (exhaust fumes etc) - but when it rains this will wash the road surface clean.
Just like brake dust it falls first on the road and where ever you drive. from there it is either swept up or more likely washed off by the rain. Most of it just ends up on the side of the road as dust.
Later that dust will be either buried or end up in open waters somewhere. Streams, lakes, rivers, ponds, the ocean.
Because it rubs out into something resembling a powder and that is what contributes to the dirt in the roadsides.
? road get bigger how in height or thicker
cos utility companies are constanly digging them up.
into the holes being dug by all the roadworks companies :)
It goes on the road alright, to make it slick in rain. It is not our rubber that goes on the road, but the oils that makes the tires.
