Resin-bound surfacing conforms to the guidance notes set out by the Resin Flooring Association (FeRFA). The quality of the resin-bound surfacing is dependent on a variety of factors. The UV 2 part polyurethane resin should always be sourced from a manufacturer who can demonstrate that they have BS EN UKAS ISO9001 quality management standards ...

The second most important part of FBE coatings is the curing agent or hardener. Curing agents react either with the epoxy ring or with the hydroxyl groups, along the epoxy molecular chain. Various types of curing agents, used in FBE manufacture, include dicyandiamide, aromatic amines, aliphatic diamines and organic acid anhydrides. [6]
Full depth reclamation: The full thickness of the asphalt pavement and underlying material is pulverized to provide a uniform blend of material. [ 34 ] [ 37 ] A binding agent or stabilizing material may be mixed in to form a base course for the new pavement, or it may be left unbound to form a sub-base course.
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).
