Existing bases must be swept, and tack coats must be applied evenly to ensure a strong bond between layers .
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. ms-22 construction of quality asphalt pavements pdf
Some might assume that a manual with roots in the 20th century is outdated. On the contrary, each edition of MS-22 has been updated to reflect new materials and methods.
: Explains the critical need to address deficiencies in underlying layers, including milling, patching, and the proper application of tack coats to prevent slippage. Plant Production , or check if your local DOT or
Below is a guide to the core phases and best practices outlined in the manual. 1. Preparation and Material Selection
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. : Explains the critical need to address deficiencies
Unlike academic textbooks, MS-22 is written for . It bridges the gap between laboratory mix design and real-world laydown operations. The manual’s core thesis is simple yet powerful: Quality is not inspected into an asphalt pavement; it is constructed into it.
