Super-lorries 'too heavy for roads'

MATERIALS

BRITAIN'S road network could crack up under the strain if the Government approves plans to allow massive 84-tonne super-lorries onto highways in the UK.

Transport infrastructure group Britpave claimed that the existing road network would not be able to hold up to the battering given by the monster trucks.

Road haulage firms are lobbying the Government to allow them to use huge 33 m-long double trailer lorries weighing as much as 84 tonnes in a bid to cut costs and pollution.

Currently HGVs are limited to 44 tonnes with a maximum length of 19 m but Britpave director David Jones claimed any proposed increases would force a complete overhaul of the road and motorway network.

He said: 'There is widespread evidence of road damage and rutting from HGVs on our motorways and dual carriageways.

'For the condition of the road network the issue is not 44 or 84 tonnes but whether the road is built with adequate strength.' Mr Jones called for specially designed reinforced concrete truck lanes to replace existing flexible carriageway construction methods on the inside lane of motorways and dual carriageways.

He claimed this would help stop roads crumbling under the pressu re of high loads.

He said: 'Concrete has four times the strength and stiffness of the range of asphalts being used on the highway network.

It makes sense to use concrete for those lanes where HGV traffic is most intense.'
