The 3rd edition of the Asphalt Institute’s MS-22, "Construction of Quality Asphalt Pavements" (2020), is a definitive, 10-chapter technical guide covering materials, mix design, plant operations, and field paving practices. It provides actionable "best practices" aimed at inspectors, engineers, and contractors to ensure durable, long-lasting pavement through proper compaction and quality assurance techniques.

Mix asphalt in individual batches. They offer high flexibility for changing mix designs mid-day.

: Best practices for manufacturing the asphalt mixture before it reaches the site. Paving Operations : Practical guidance on placing the material correctly. Compaction

Proper compaction of the subgrade to prevent future settlements.

Performed with static steel-wheeled rollers at lower temperatures to remove roller marks and smooth out any surface imperfections. 7. Joint Construction and Quality Control

Rollers must operate within a specific temperature window. If the mix cools below a certain threshold (typically around 175°F to 200°F depending on the binder), the asphalt becomes too stiff to compress. Continued rolling at low temperatures can fracture the aggregates and destroy the pavement structure. 8. Joint Construction Techniques

Aggregates make up roughly 90% to 95% of the total mix weight. According to MS-22, aggregates must possess specific characteristics:

The MS-22 Construction of Quality Asphalt Pavements manual is a valuable resource for contractors, engineers, and other professionals involved in the construction of asphalt pavements. By following the guidelines and principles outlined in MS-22, contractors and owners can ensure that asphalt pavements are constructed to the highest standards, providing safe, durable, and sustainable infrastructure for communities. Whether you are a seasoned professional or just starting out in the construction industry, MS-22 is an essential resource for achieving success in asphalt pavement construction.

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.

MS-22 is a comprehensive manual published by the Asphalt Institute that provides guidelines for the construction of quality asphalt pavements. The manual covers various aspects of asphalt pavement construction, including materials, design, and construction techniques. It is widely used by contractors, engineers, and other professionals involved in the construction of asphalt pavements.

If you cannot obtain the PDF directly, consider the Asphalt Institute’s online course "Construction of Quality Asphalt Pavements," which includes a digital copy of MS-22 as part of the tuition. This is ideal for contractor training programs.

The Asphalt Institute's is a must-have manual. It covers the entire process, including: ✅ Subgrade preparation & tack coats ✅ Mix production & transportation ✅ Placement & compaction best practices ✅ Smoothness specs & troubleshooting

The manual is designed to ensure that Hot Mix Asphalt (HMA) pavements are constructed to meet specified performance requirements, thereby enhancing longevity and reducing maintenance costs. Core Components of the MS-22 Guidelines
