We maintain many of our roads with a mixture of reclaimed asphalt, sand and gravel which is applied and then rolled.  We find that it lasts longer than dirt/gravel and over time has created a compact road bed, especially in areas that get a lot of sun.

It is slightly less dusty than dirt/gravel, but still creates dust when the roads are dry for long periods. One of the members of our association is claiming that recycled asphalt particles in the dust is a major health hazard. He has downloaded Material Safety Data Sheets from various companies that, he says, support his claim. The data sheets are from companies whose employees are exposed on a daily basis so I don't know how relevant that is to our situation.

Anyone have any experience in this area?
