lot will start setting before it is all finished .

Even if it does there's no real problem. If you've got the sort of
mixer that goes on a rotating stand it may make life easier if you can
position the mixer so that you shovel the ballast straight into it
then rotate and tip straight into the trench, rather than barrowing
wet concrete (which is heavy)
