I believe you are correct, Larry! I think this is a lime spreader.
When building up a road base, the ground has to be a certain 'hardness' to keep the road from settling. One of the ways to harden the sub roadbed is to mix powdered lime into the clay hardpan. This truck would spread the powdered lime and then a sheepsfoot roller would come in behind to mix and compress the soil.
