We started our last paver install of the season on Tuesday. The soil was a heavy clay soil. We excavated and time came to tamp the subsoil. Normally, I automatically tamp the subsoil with a jumping jack if it is a heavy clay soil. However, on Tuesday I didn't have the jumping jack with me and for a minute, I thought, f*** it, we'll just use the plate tamper. Then a voice said, " you a**hole, what are you doing, go get the jumping jack." I went and got the jumping jack. The jumping jack tamped about two inches more than the plate tamper in that soil. I know that the ramming action of the jumping jack works better on a heavy clay soil, but I don't know a lot of guys in my area that use it. I believe that sometimes the jumping jack overtamps and is overkill, say in a sandy soil. My question is, what do you guys do?
