By covering every critical phase from design and materials to placement and quality control, remains the single most important guide for paving professionals who are committed to doing the job right.
A surprising amount of damage can occur between the plant and the paver. MS-22 details:
To achieve a pavement that meets the high standards of the MS-22 manual, field crews must prioritize the following:
After implementing MS-22 recommendations (saw-cutting joints, re-tacking just before paving, and using a small vibratory roller immediately), joint densities rose from 88% to 94.5% – well above specification. The agency waived a $200,000 penalty. The PDF paid for itself a thousand times over.
Truck beds must be clean and lightly coated with an approved, non-petroleum release agent to prevent sticking. Every load should be securely tarped to retain heat and protect the mix from rain or cool winds, preventing (cold spots). 5. Surface Preparation and Tack Coats
Asphalt mixing plants—whether batch plants or drum-mix plants—must be calibrated precisely to produce a uniform mixture that matches the JMF. Key Production Factors
Typically requires achieving 92% to 97% of the theoretical maximum density (Gmm).
: Detailed guidance on storing aggregates to prevent segregation and managing asphalt storage tanks and delivery lines. Surface Preparation
A perfectly engineered asphalt mix design can fail prematurely if it is improperly produced, hauled, placed, or compacted. MS-22 addresses the variables controlled during the construction phase to prevent common distresses like: Permanent deformation from heavy traffic loads.
Proper drainage around stockpiles is critical. Excess moisture increases plant fuel consumption and can lead to incomplete drying. Asphalt Binder Handling
