I have resisted as much as possible doing any paving design. I don’t like civil site work. I stick with structures only. I have come into a circumstance where I must specify some paving and I don’t have any good references. Are there good references that describe concrete paving in simple terms? I don’t have to do an active road design, more like parking lot type traffic, real slow. I have heavy tank trucks using the road, not constantly, maybe several times a day. The section of the road I have to design is 28 feet wide and about 150 feet long. I’m thinking the subgrade is probably going to be existing site soils, no significant prep, base course, etc. I may have crush stone base under it since the real road beyond my limits is a gravel road.
I have an old civil engineers handbook. It has a 1 page section on concrete paving. It doesn’t really discuss design much at all. Are there any references that illustrate concrete paving design by a few cookie cutter equations? Any good websites with references?
I downloaded the NAVFAC PCASE program. It is a bit overkill for me. Toying with the program I came up with a 6.5” slab. I’m not sure if I used it right. I’m thinking an 8 inch slab with nominal reinforcing, say #4 @ 16” o.c. top bars with one joint splitting the 28 ft. width and probably 7-8 joints on the length. Does that sound reasonable for tank truck traffic from someone with paving experience? My gut says it’s fine, but I don’t like putting a design on my drawings that I can’t justify with calculations of some kind.
Thanks for any help.
