While MS-22 does not replace volumetric mix design, it explains how to construct a pavement that meets Superpave criteria. For instance, achieving the specified air voids (typically 4%) is impossible without proper compaction – a theme MS-22 covers exhaustively.
The Asphalt Institute’s MS-22 manual, "Construction of Quality Asphalt Pavements," serves as a definitive guide for producing durable roads, emphasizing that quality stems from a chain of processes including design, materials, and production. The manual highlights compaction as the critical factor in pavement lifespan and warns against paving in unfavorable weather conditions to avoid stripping.
