Fibre reinforced seals comprise a sprayed sealing treatment consisting of a layer of glass fibre strands sandwiched between two coats of a polymer modified bituminous emulsion. The fibres are applied randomly to form a mat that resists reflective cracking. Finally, a layer of aggregate is spread and rolled in the conventional manner. Under normal conditions, the surface may be opened to traffic immediately, as with conventional sprayed seals. This report provides advice on the: - type of pavements where a FRS is applicable - materials required to produce a successful FRS surfacing - design of a FRS surfacing - field procedures.
