Vehicle crossover and tarmac drive, Knuston
We were approached by a regular customer of ours, who had been redeveloping a large property in the village of Knuston in Northamptonshire. The driveway had already been block-paved in the main. The entranceway was being made bigger with new walls and electric gates, and the customer wanted tarmac for this part. There was an existing crossover, in tarmac, but it was very tired and falling to bits, so it was decided to resurface this at the same time.

Objective
Our objective was to lay tarmac in within the new entranceway and between the new stone walls, but also to excavate the existing crossover and to relay with tarmac, all at the same time.
About the project
Whilst our customer was having completing the remainder of the block paving within the site, and building the walls either side of the new crossover, we approached Highways regards resurfacing the existing crossover. We were told this would need a Section 171, as opposed to a Section 184, which is to create a new crossover from scratch. In deciding method of traffic management we had to consider that the footpath would be out of action for 2 days. As there was no footpath on the other side of the road, we didn’t have the option to simply close the footpath and send the pedestrians over to a footpath on the other side of the road. The pedestrians would have to go in the road, via a dedicated ‘pedestrian walkway’, and for this to be possible we would need 2-way traffic lights to close the lane nearest. This would also enable us to park works vehicles adjacent to the site.
We set up the traffic lights at 8am on day 1. We proceeded to excavate the existing crossover to the required depth for type 1 MOT and for the crossover construction which in Northamptonshire is 100mm of 20mm-size base course, and 20mm of 6mm ‘top-coat’. The area to be laid in tarmac extended beyond the crossover at the front, between the new walls that had been build to the front of the property, and all the way to where the block paving had been laid in the site. The type 1 that had been laid and compacted by the customer was checked for levels and didn’t require any further work.
The spoil was removed from site by the end of day 1 and preparations made to tarmac the following day. On day 2 we arranged for base course to be delivered at 8am, and it arrived shortly after. The tarmac was delivered on a lorry with chutes to the rear, which we used to fill wheelbarrows. The base course was in and laid before 11am. The 6mm ‘top-coat’ was delivered around 1pm and this was in and compacted within an hour and a half.
The new crossover and tarmac laid to the rear of the crossover was cool to walk on within a couple of hours. The traffic lights were taken down ready for the heavier teatime traffic, but we kept traffic off the crossover until the following morning, when it was open and for the customer to use.
