Most pea gravel will roll around under traffic forever. I suggest that
you ask for graded base course material from a local aggregate
supplier, preferably one that is supplying material for highway
construction. It is designed to attain maximum density with the proper
moisture content and wheel or vibratory compaction. Heavy rain will
wash out the fines and degrade the stability, but it is ideal as a
base for concrete or asphalt.
