I'm fairly sure than in the UK, Asphalt aggregates are made with a planned obsolescence in them.

Of course, I only have my own personal experience and just a little probing of someone who works in the industry who has evaded my questions about it...

However, despite the large amount of traffic, I can't explain why new surfaces will disintegrate in about ~4 years. We're in 2017; some roads that have been made 50 years ago are still good to go, while others, new ones just fall apart as soon as there are a couple of days of frost.

My take on this is that it's all made by the large contractors to get more or less unlimited work from the councils, as the roads needs to be repaired every few years...

Am I being cynical? ;-)
