ABSTRACT:
A structural material is disclosed which comprises pieces of shredded rubber bound together using a bituminous binder with the size of the pieces of rubber being big enough for an interconnected void volume to be provided within the structural material in the range of 10 to 50% with the weight of rubber being substantially greater than the weight of binder material. The invention also relates to a roadside drain in which such structural material has been applied as an upper layer above a layer of drainage material such as 30 mm aggregate leading down to a porous drainage pipe.
