Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pavement material for promenades or walking roads that is economical, durable, resistant to weather and decorative with the colors of aggregates, uses a one-component moisture-curing type polyurethane binder of easy application work management, causes reduced deterioration of physical properties, even when moisture-including aggregate is used, inhibits foaming and whitening, and gives a suitably pleasant walking sense. SOLUTION: The addition of cement, when mixed aggregates, for example, crushed stones, sand, rubber chips are agglomerated with a one-component moisture-curable urethane binder, and the use of the diphenylmethane diisocyanate including >=40 wt.% of the 2,4-isomer make the pavement material have excellent workability and resin properties.
