The paver should maintain a slow, continuous uniform speed. Frequent stops and starts cause the screed to settle, creating bumps in the road. Proper compaction of the base ensures it can

Proper compaction reduces air voids, preventing water intrusion and premature loss of integrity.

Moisture control in aggregate stockpiles is a primary concern. High moisture content requires more fuel to dry the aggregate, slowing production and increasing costs. MS-22 recommends sloping stockpiles and placing them on paved surfaces to facilitate drainage and prevent contamination from underlying soil. The Drying and Heating Process Preventing Segregation The manual outlines a sampling and

The asphalt paver takes the uncompacted mix and lays it to the desired width, thickness, and initial profile. The Paver Screed: The Heart of the Operation

MS-22: Construction of Quality Asphalt Pavements is the industry-standard manual published by the Asphalt Institute

According to MS-22, a high-quality pavement is not achieved by paving alone. It requires a holistic approach across five critical phases:

A proper prime coat is critical for performance.
