Car Park Heathrow Airport
Asphalt Reinforcement Services Ltd secured a 50,000m2 GridSeal®contract incorporating GlasGrid® 8550 and Sealoflex® SC33 at the Pink Elephant Business Car Park, Heathrow Airport reputed to be the longest car park in Europe. The contract commenced June 2005 and was completed October 2005.
Consultants Project Techniques were faced with the common difficulty to minimise the on-set of reflective cracking following the construction of a thin, flexible overlay on a concrete base. This problem is created by larger movements of the expansion and contraction joints in the concrete following a new bituminous overlay, therefore increasing the risk of reflective cracking.
GridSeal® was selected using the proven GlasGrid® technology to mitigate the onset of reflective cracking.
The GridSeal® system is designed to increase the design life of the pavement by a factor of 4-5 times compared to a conventional design making it a cost effective solution to reflective cracking.
GlasGrid® IM was supplied to Nottinghamshire Highways Partnership for reinforcement work undertaken on Shire Oaks Road, Worksop.
GlasGrid® IM is fluorescent in colour and the Shire Oaks Road pavement design called for a product which could be used with a black sand carpet. The combination of the two resulted in significant cost savings and also increased productivity times on-site.
In 2010, Defence Estates awarded Colas’ Airfield Division a multi-million pound project to refurbish the airfield at Mount Pleasant Airport in the Falklands Islands. Mount Pleasant Airbase, East Falkland is the only joint military and civilian airfield on British soil.
The project, which ran from Autumn 2010 to early 2011, was the first major refurbishment of the airfield since it was constructed in 1985 and was planned to coincide with summer in the southern hemisphere and the 25th anniversary events to commemorate the Falklands war.
Work included resurfacing both of Mount Pleasant’s 2.4km runways, as well as all of its taxiways, links and loops and involved refurbishment of all the asphalt surfaces and replacement of all airfield ground lighting together with specialist surface treatments laid by Asphalt Reinforcement Services Ltd and civil engineering. Much of the work was carried out at night and under very extreme weather conditions. The Falklands is infamous for its ‘four seasons in one day’ climate.
Significant resources and logistics were required to complete the project, which was 8,000 miles from the UK, including two mobile asphalt plants. Colas’ own Warrington plant supplied the entire bitumen and bond coat required for the project. Over 12,000 drums of binder were filled and transported.
It is critical to get main runway open in time every Friday to maintain the Island’s key supply lines. The runway had to remain operable for military use all week. A squadron of RAF Typhoons is based here and the phasing of our work has been calculated to allow take off within 15 minutes’ notice – Simon Downing, Airfields Business Manager at Colas
GlasGrid® 8502 was used within the overlay of Alpha Taxiway Phase 3 as a detailed repair system above both the V channel drainage system and both longitudinal and transverse ducting channels.
CompoGrid® CG100 was chosen to arrest the reflective cracking from utility trenches at this very busy urban location. The speed of the process and strength of the reinforcement system meant that two bituminous layers were unnecessary and the whole contract was completed in one Sunday, rather than two.
The A212 Wellesley Road is an extremely busy dual carriageway road through the centre of Croydon. It was in a poor condition and suffering from reflective cracking, made worse by winter weather.
It was decided to remove the bituminous overlay down to the concrete (100-200mm).
CompoGrid® CG100 was chosen and adhered to the planed concrete using 200 pen bitumen.
Bardon Contracting used their polymer modified bitumen mixes to further enhance the overall long term performance and durability of the carriageway. The binder course was 60mm nominal thickness which applied over the CG100. A 40mm surfacing course completed the installation.
“The speed of GlasGrid® installation is impressive”

The A515 Lichfield Road suffered from wheel tracking, fretting and cracking problems due to the high volume of HGV traffic.
The haunches were excavated to a depth of 400mm and replaced using recycled material giving a considerable saving in both virgin materials and a great reduction in carbon footprint.
ARCDESO® was used to model the lifetime performance of the pavement and CompoGrid® and SealoFlex (CompoGridSeal) was chosen to strengthen the pavement, arrest reflective cracking and considerably extend pavement life.
Using the CompoGridSeal system allowed Staffordshire County Council/Enterprise to reduce the total inlay thickness by 100mm as well as the contract duration on this innovative scheme.
Have you ever considered how you will deal with the reinstatement after a utility contractor has excavated through a reinforced asphalt on the network. Well here is the simple answer.
Firstly, you need to specify the correct reinforcement at the outset. GlasGrid® is a fibre glass reinforcement that has a polymer resin coating to provide long term protection against mechanical abrasion and water ingress, beware of uncoated glass systems. GlasGrid® is designed to provide uniform tensile strength in the remaining asphalt even after a utility company has excavated through the reinforcement. The pictures say it all. It only requires saw cutting approx. 50-100mm wider than the main excavation to just above the existing reinforcement. This will allow the utility contractor to reinstate with an overlap ensuring the asphalt overlay remains reinforced. This process is quick and simple and may be undertaken by the utility contractor themselves.
The CRCP pavement was exhibiting excessive cracking as well as surface loss between junctions 6 and 7 of the M18.
CompoGrid CG100 was installed directly onto the continuously reinforced concrete pavement following the application of a proprietary tack coat.
A polymer modified bond coat was applied at a rate of 2.0kgs/m2 followed by CG100 installed by Asphalt Reinforcement Services trained operatives using purpose designed and built mechanical applicators.
The overlay materials used were HDM binder course and MasterPave/Masterflex surface course.
GlasGrid® GG200 (8502) was incorporated within the pavement design of the £320m M1 widening scheme between Jct 25 –28 to strengthen the pavement and deal with any potential movement between the new and existing carriageways.. Working for Bardon contracting bespoke mechanical applicators were used to maximize productivity on this contract.
