Here in the desert we have to allow for expantion and contraction. Here is what I do
I get some plastic anchors
The piece of wire is from a spool of wire one would use to wire rebar together. You can get it at Home Depot
I drill a 1/4 in hole in the concret roadbed every 2 or 3 feet. Insert the plastic anchor then bend the wire over the tie.
I then mix my ballast in a mixer with portland cement The mixture is dry. I add color to the mix to tone down the gray I then use this mixture to ballast my track.
After everything is in place I wet the ballast and when it dryes everthing is held fast. Wash outs are a minamum
If I need to work on the track or replace sections because some local gentry has stepped on the track it is very easy to remove.
