I have a gravel driveway uphill. I put new 1/2" rock gravel in last fall because of washout. I also spread concrete and sprayed it, but it didn't take. I have a 05 Harley Davidson Road King custom that I can't get up or down the driveway without almost dumping it.
Can I put anything on it to harden it up enough to get my bike up and down? It's too long to cement or asphalt it.
