The minimum recommended crushed aggregate base thickness is 4” for most projects. Layers less than 4” thick are possible, however, they do not add much strength to the overall road or compound structure and materials from the underlying sub base or sub grade may contaminate a substantial portion of the layer and inhibit drainage. In addition, they are difficult to compact, they are frequently subject to quantity overruns and it is difficult to construct and maintain smoothness in aggregate layers thinner than 4”. If possible, place your compound gravel after you have installed your system grounding and electrical runs.
Access roads may call out for 1” crusher run gravel for the access road and a compound base of #57 stone. Both aggregates are fairly close in pricing with an average price of $8.43 at the pit. The default pricing used in the road and compound pricing in "My Estimator" includes the cost that would be charged by t he excavating or site development contractor to furnish, deliver and grade the base material.
We recommend that you contact our valued excavators and site development companies to obtain additional information about your project-specific base requirements.

Whenever you receive a quotation from a contractor that appears to be too low, identify if they have the proper insurance, safety training and the expertise to complete the job. Oftentimes they don’t! If a supplier’s or service provider’s pricing is also extremely low, ensure that the materials and/or design meet the specifications or that they’re competent in providing their service offerings. Check references at least twice and you’ll only have to cut the purchase order once!
