Chip bored

Letters

No matter what the advantages of scattered sharp chippings on roads (NCE 1 July), the disadvantages include actual danger and damage.

Another method needs to be found.

Whatever is supposed to happen, or is specified, loose chippings are always left and most traffic ignores the posted speed limits which are ridiculously low for main roads anyway.

This is the 21st century: We need to find better surfacing methods at sensible cost.

That also includes major road surfaces that do not break up within weeks of use.

Pavement design is unlike other civil engineering in that it is repetitious and mass produced. Solutions, once found, should be repeated until a genuinely better one is found. We would not accept precast concrete products, for example, with failure rates and inefficiency like this.
