Compaction is perhaps the most time-sensitive aspect of construction. MS-22 notes that density is the single most important factor in pavement life; low density allows air and water to penetrate, leading to oxidation and stripping.
The manual breaks the compaction process into three distinct phases:
MS-22 also addresses temperature differentials—warning that cooler spots in the mix (often caused by segregation or truck bed cooling) can lead to inadequate compaction in localized areas, creating weak spots in the pavement structure. ms-22 construction of quality asphalt pavements pdf
Longitudinal and transverse joints are statistically the most likely points of failure in an asphalt pavement. MS-22 dedicates significant attention to joint construction techniques.
No chapter is more dog-eared than the compaction section. MS-22 teaches: Compaction is perhaps the most time-sensitive aspect of
A search for the ms-22 construction of quality asphalt pavements pdf typically suggests a user needs quick access to specific sections. Below is a breakdown of the manual's key chapters and their practical applications.
Poor joints are the first to fail. MS-22 provides detailed schematics for: ms-22 construction of quality asphalt pavements pdf
The manual emphasizes that no pavement is stronger than the layer beneath it. MS-22 dedicates significant space to:
