The three rows of stone blocks or setts forming the channel make a pleasing contrast with the tarmac: warm cream against purplish dark grey; coarse texture against fine-grained. The setts are the colour of Clunch but it seems unlikely that a form of chalk would be able to withstand wetting and the passage of vehicles. Page 23 of the glorious Hertfordshire Strategic Stone Study from Historic England https://www2.bgs.ac.uk/mineralsuk/download/EHCountyAtlases/Hertfordshire_Building_Stone_Atlas.pdf illustrates a similar construction in St Michael's Street, St Albans. Upper Heath Road is unlikely to be different. The kerb (which could be mistaken for concrete) is identified as Sarsen Stone, probably from Buckinghamshire, and the setts as Granodiorite, an igneous rock well able to withstand wear and tear, possibly from the Newry area of County Armagh; 'Newry Granite', according to Wikipedia.
