A method of constructing a resilient surface layer of particles bound together and to a base surface comprises uniformly dropping dry rubber particles from a moving apparatus and spraying the particles with a liquid, water based, latex binder as the particles are dropping, the apparatus comprises a movable vehicle with a particulate spreading assembly comprising a hopper with a controlled orifice, and a spray system with an array of nozzles directed to intersect the path of the particles after leaving the hopper and before the particles reach the base surface.
