23、 are fully loaded for each trip. Depending on the type of material to be transported. a reasonable compromise on which tn base an agreement would be R mass or volume of hetween 70% and 80% oE the nominal capacity oC e,lcli vehicle used. Such an agreement should he reached heFore carting is commenced

24、. Reclearing (Suhclause 5.5).
