Yes, in fact some rhododendrons root themselves from branches that touch the ground.

If you want to do it a little more scientifically, take a pot of moist potting mix, place it under a low branch of the rhodie you want to root, and "pin" the branch down so that one side of the branch is on the moist soil. Keep it evenly moist for probably a month or 6 weeks and then start checking for root formation by gently moving a little of the potting mix away for a look.

The branch you want to root must be a mature branch with bark. It's not going to be successful with new growth.

Even more scientific would be to bind a wad of sphagnum moss around a branch, and tie a plastic bag over the moss to keep it moist. (you can do this if your plant doesn't have any branches near the ground). This process is known as "air-layering" and here's a link to a good article on how to do it.
