A tidy, more versatile solution for smaller areas of tarmac
Hand lay is used across EV charging hubs where a paver cannot reach around charger bases, bollards, kerb lines and the tie-ins between charging bays and existing surfaces.
The asphalt is distributed by wheelbarrow to the working area and levelled out using a rake. On a live EV car park this is often the difference between a bay that looks finished and one that does not.
The person levelling out should set points around the area to work to, or use existing features such as kerbing lines. This helps create correct falls and levels, which matters on EV bays where surface water needs to run away from the charging units. Depths of asphalt are checked throughout the works to make sure required depths are being met and the asphalt is being laid consistently.
Grades of Aggregate in Asphalt
There are three main types of surfacing products AC 6, AC 10 and AC 14, these products are generally used as standard specification requirements. For heavier use and when specified, products such as SMA (Stone, Mastic, Asphalt) or Hot roll are used.
- AC 6 – Wearing course for footpaths and lightly trafficked areas such as driveways and courtyards.
- AC 10 – Surface layer rural roads, car parks and driveways, which are considered lower stressed areas.
- AC 14 – Mainly used for the heavier trafficked areas such as busy main roads and motorways.
- AC 20 – The Binder course is placed between the surface and base layer to help bind and create a solid foundation.
- AC 32 – Base course used to provide a solid foundation for your binder and surface courses to be laid on.
- SMA and Hot Roll Products – Used in higher stressed areas such as car parks or on road bends – generally in areas where turning is apparent.
