As the adopted prolile ofthe road was shown on the plans, to deter-mine the cut or fill on center line it wasonly necessary to make a simple computation,using the profile grade elevation and theelevation of the top of the stake. This cutor fill was then marked on the side of thestake which faced the center line; one of theassistant resident engineers did this marking,and he could mark as many as three miles ofstakes in a day. With the stakes construction foreman could, with a levelrod and hand level, determine the elevation road the concrete pavement w-as 4 ins. () thick, with a crown of 2% ins.
