There's a previous thread on AAM
here but does not give much advice. Suppose its all down to contractor and products used but I did see one recently which had not worn well at all. On the sections where there was not much wear and tear it still looked alright but the sections where the cars had driven over it did not look good at all.
This website has been around a long time and is usually good although I see they have had an overhaul recently.
This section might help.
