  • Some practical Aspects regarding the handling of Dolerite

    dolerite mass need to be loosened by judicious use of explosives. Material for surfacing or Crushed Stone base (G1 & G2) aggregate will normally only be found in the third horizon, which, although jointed, is normally very hard and non rip-able. This implies that a proper quarry and well-controlled crushing plant will have to be established, especially because of the hardness of dolerite and

  • Some practical Aspects regarding the handling of Dolerite

    Claims have been made that stockpiled dolerite, and even dolerite within a pavement, can weather and deteriorate dramatically over a short period. Cases are bandied about where very acceptable stockpiled or even layered dolerite material totally failed re-evaluation after a year “the PI returned” and “the CBR was lost”. The authors also have experience of
