Abstract
An artificial surface for the growing of turf forming grasses and other plants, comprising a mixture of rubber, a polymer modified bitumen emulsion and slow release, plant nutrient containing particles, mixed in sufficient proportions and to a substantially even distribution of each of the rubber, emulsion and particles throughout the mixture so that, when laid and cured, the mixture uniformly produces a water permeable, heat conductive surface having air pockets through which a root system of the turf forming grasses and other plants can penetrate, the plant nutrient containing particles being trapped within the surface for slow release of plant nutrient to the root system.
