Expansion Joints--Terms and Terminology: NOSING MATERIAL

Nosing Material--

A resin material (usually polyurethane based) with aggregate additives that is mixed and poured in the field on each side of a structural expansion joint gap. The material when cured is less rigid than the adjacent concrete substrate and as a result is more forgiving of traffic impact and suddenly applied vehicle loads. A high performance nosing material should be conservatively loaded with aggregates so as to preserve flexibility and avoid brittleness.

Used as a bedding material beneath cover plate systems, a conservatively-aggregate-loaded nosing material can be used as a leveling course to take any play out of the plates while additionally serving to absorb the loud bangs typical of plates mounted directly to hard, uneven, concrete surfaces.
