This note presents the way the RoadMat database is organized. As a general rule, the database is currently focused on products that are essentially NOT standardized, like emulsifiers, polymers, rejuvenators... In other words, you will find little information regarding standardized products such as standard paving grade asphalt binders or mineral aggregate. Still, some special grades of these materials can be found, but only when they are not standard, like multigrade or clear binders. More details on the database are now given.
