M1 Widening J25-28 - a green solution
Our mobile concrete batching plant provided a green solution for dealing with thousands of cubic metres of coal tar contaminated road planings (Which are classed as a Hazardous Waste) that were produced during the removal of the existing hard-shoulder. Coal tar is carcinogenic. PJD used the coal tar contaminated road planings, batched on site using our own mobile batching plant, for wet lean that we placed in the lower base layer. Making use of a hazardous waste that would otherwise have been sent to landfill. This produced a saving of approximately £3-£4Million in disposal costs and a further saving in not having to import thousands of tons of virgin aggregate.
Avoiding transporting the tar planings to a tip and avoiding transporting the virgin aggregate to site also produced a huge saving in carbon emissions – approximately 140te.
PJD works on the M1 junctions 25-28 comprised: 23,500m of CSB; 32,300m of 'V' channel; 4,700m of ground beam; 250m of HVCB; 24,000 cubic metres of wet-lean mix PJD batched (coal tar planings) ~ PJD also batched the concrete for the CSB, 'V' channel, ground beam and HVCB, using our mobile batching plant, kite-marked to BS EN 206-1 & BS 8500.
M25 Section 1
PJD works comprised: 39,400m of CSB, 12,070m of ‘V’ channel, 455m of retaining wall, 23,600m slot drain, 5,500 cubic metres of PQ Concrete.
We operated 24hrs a day/7days a week during some stages of the project in order to achieve the demanding programme. This project overlapped with the M25 Section 4 Project.
M25 Section 4
PJD works comprised: 23,750m of CSB, 49,810m of slot drain, 17,335m of retaining wall, 48,400 cubic metres of PQ Concrete, 41,150 cubic metres of wet-lean.
We operated 24hrs a day/7days a week during some stages of the project in order to achieve the demanding programme. This project overlapped with the M25 Section 1 Project.
The M1 Motorway near London, between Junctions 6A and 10 - PJ Davidson (UK) Ltd was awarded the contract to slipform 32 kilometers (20 mi) of 900 millimeter (35.4 in) tall concrete step barrier (CSB), 28 kilometers (17.4 mi) of v-channel, and 3000 meters (9843 ft) of slot drain.
We hit the 1,000,000 linear meter (3,280,840 ft) mark for concrete slipforming in the UK on this project .
