Abstract
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.
Claims13
A method of constructing a resilient surface comprising particles of resilient material bound together and to a stationary base surface by a liquid binder, the method comprising the steps of, first, dropping particles of resilient material from an apparatus moving relative to the base surface, the particles falling in a line transverse to the direction of movement of the apparatus and substantially the width of the apparatus, toward the base surface and second, coating the particles with a liquid binder by spraying the uncoated particles with liquid binder after the particles are dropped toward the base surface from the apparatus and before the particles reach the base surface, without otherwise manipulating the particles while falling from the apparatus to the base surface.
A method of constructing a resilient surface comprising particles of resilient material bound together and to a stationary base surface, the method comprising the step of evenly distributing resilient particles over the base surface from an apparatus moving at a uniform rate relative to the base surface, the particles falling to the base surface at a uniform rate in a line transverse to the path of the apparatus, and being coated with liquid binder after being released from the apparatus, without otherwise manipulating the particles while falling from the apparatus to the base surface.
