Oversees testing for compaction and temperature to ensure specifications are met.
: Ensuring the base is stable, properly graded, and free of debris. Mix Logistics ms-22 construction of quality asphalt pavements pdf
The manual emphasizes that quality must be built into every step of the process, rather than trying to test quality into the final product. Oversees testing for compaction and temperature to ensure
The mixing cycle must ensure that 100% of the aggregate particles are uniformly coated with the binder. The mixing cycle must ensure that 100% of
Storage tanks must be completely drained and cleaned when switching between modified (e.g., polymer-modified) and unmodified binders. Job Mix Formula (JMF) Verification
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.
The screed floats on the asphalt mix. Its thickness is governed by a balance of forces, including tow speed, angle of attack, head of material, and mix temperature.
