Abstract/Contents:"The physical properties of sand-soil rootzones were examined after the incorporation of rubber crumb. Four size grades of rubber crumb were either mixed into the rootzone at rates varying from 0-50% by volume or applied on the surface, with depths ranging from 0-20 mm. The hydraulic conductivity of mixes containing rubber crumb tended to increase, especially when incorporation rates exceeded 30% (v/v). Hydraulic conductivity was greatest when medium grades (0.25-1.5 mm) of rubber crumb were used. With coarser grades of rubber crumb, it was thought that significant interpacking took place between the rubber crumb and the rootzone mix. Bulk density decreased as the incorporation rate of rubber crumb increased and bulk density values were greater for the coarser grades of rubber crumb (1-3 mm or 2-8 mm material). Total porosity decreased with incorporation rate for the coarser grades of rubber crumb but was hardly affected by fine (0.125-1.0 mm) and medium grade material. Capillary porosity decreased with incorporation rate and finer crumb size, while air-filled porosity was greatest where medium grade material was used. Increasing rates of rubber crumb reduced surface hardness and shear strength. When used as a top dressing material, increasing depth of rubber crumb caused increases in total porosity and air-filled porosity and decreases in bulk density, capillary porosity, hardness and shear strength. The effects of crumb grade were generally not significant, although for hydraulic conductivity values decreased with depth for fine grade material. The use of rubber crumb gave advantages of increased hydraulic conductivity and reduced bulk density and hardness. However, the consequences of large quantities of rubber crumb on water retention and surface stability must be considered. In general, medium grade rubber crumb (0.5-1.5 mm) appeared to be the most effective for use with sand-dominated rootzones."
