- Longitudinal Joints: The manual advocates for proper alignment and the use of a "notched wedge" joint or a vertical face joint to ensure maximum density at the edge where two lanes meet. A common failure is the "honeycombing" of the edge, which must be avoided by proper screed operation and edge confinement.
- Transverse Joints: These are constructed where the paving operation ends for the day. MS-22 details the construction of "saw-cut" joints to ensure a smooth vertical face and a tight bond, minimizing the bump often felt when driving over a construction seam.
Quality pavements do not happen by accident. They happen when you follow a proven system – and that system is MS-22. Here’s what you can do: : Detailed techniques
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.

Joint Management: Poor longitudinal joints are a common point of failure. Best practices include using a cutting wheel to trim cold edges before applying a fresh tack coat. 4. Quality Assurance (QA)
