CASE FILE No: 501

Client: Nottinghamshire Highways

Site: A617 Millennium Way Rainworth

Contractor: Lafarge Tarmac

Product: PGM-G100/100

Date: 07/03/2015

The A617 Millennium Way, Rainworth, was opened in the year 2000. The original construction comprised a high modulus base 200mm thick, 60mm of binder course and 40mm of SMA surface course. After a few years of use, signs of reflective cracking from the lower joints became apparent along the whole length of the road and in more recent times surface course failure was occurring in large areas. Core samples were taken and while the structural integrity of the bituminous layers was good there was no bond between the base and binder course layer. The assumption was made that this was contributing to the surface course failure with the upper layers flexing over a stiff base.

Following consultation with Lafarge Tarmac, the decision was made to plane the existing material to a depth of 140mm, to ensure all the existing binder course layer was removed and lay an asphalt reinforcing grid. This would ensure an excellent bond between the layers and prevent future reflective cracking. Lafarge Tarmac proposed Asphalt Grid Systems limited to supply and install Tencate PGM-G100/100 as they had previous experience and success with it in Nottinghamshire. Additionally, the proposed binder course, ultilayer 20 and surface course layer ultipave D, would utilise polymer-modified binders to give a highly flexible road surface.

The total area of the scheme was 12,000m². Due to the layout of the road – part dual carriageway, roundabout and single carriageway, it was agreed that the works would be carried out under a full road closure and dual shifts utilised to ensure the road was reopened as soon as possible. The asphalt grid and bitumen bond coat was laid over two shifts (Saturday and Sunday evening) to tie in with Lafarge Tarmac’s programme. All works were completed within 9 days and the road reopened a shift earlier than originally programmed.
