The base was tarmacadam; not sure of the specifics but I'm happy to check up and let you know in the New Year.

Yeah would appreciate that.

we've had problem in the past with the resin (not yours) delaminating from the asphalt/tarmac

would like to know the specific bituminous material used for a big un like this.

That's a bloody good question, bobbi o. What's the latest thinking when it comes to overcoming the risk of de-bonding? I've not seen anywhere near as many 'blisters' over the last couple of years, so is that because the weatther has never been warm enough to be a problem, or have there been improvements with the resins?

Resin blistering from the surface is a problem associated with resin BONDED. This job was resin BOUND.

Our standard substrate spec for footpaths is

"Construction of base
For pedestrian traffic
From base upwards, construction is typically 50-100mm of well compacted non-frost susceptible Type 1 sub-base to DoT Clause 803, followed by 40mm of 14mm close graded asphalt macadam surface wearing course to BS 4987 Part 2: 2001 Clause 7.3 which has been laid to a fall of not less than 1% to allow for good drainage and water run-off. The surface must be smooth and flat. Alternatively apply to sound well constructed and smooth concrete substrate. The base should be sound, clean and dry. New tarmac surfaces must be allowed to cool and gain strength for not less than 24 hours at 20oC. Ronacrete’s Technical Department will be pleased to discuss permeable substrates".

Have been watching that area gradually come together over the last year as we go past the "Green" many times on the way into central London, and noticed it was finished and Looks Very Good indeed, Nice work Simeon :cool:
