After years of use, #4 Crushed Stone still shows a coarse, open texture rather than a packed finish. Its crushed shape leaves large spaces between pieces, allowing drainage while helping the stone hold position under heavy loads. Those spaces are intentional, not a sign that the material should be tightened into a travel surface.
West of the Cascades, rain can sit on glacial hardpan beneath topsoil and weaken a drive or shop pad. In the wetter regions, place this stone in the supporting course and give water a route away from the hardpan. This placement keeps the open stone below the working surface. That use fits pads and drainage work around Puget Sound and the Olympic Peninsula. East of the mountains, seasonal frozen ground and runoff still make an open support course useful where heavy traffic needs stable support during the wet season.
