 · Asphalt shingles are a broad category of shingle roofing that encompasses anything made with layers of asphalt fibers as part of its composition. They have been in use for many decades to create asphalt roofs, starting out as flat, three-tab or one-tab versions in their original design and progressing to today's more durable and decorative styles.

The characterization of the chemical functional types gives a fundamental approach to the relationships between asphalt composition and asphalt properties, and the performance of asphalts and asphalt-aggregate mixtures.
