Excessive air voids can be either a mix design or a construction problem and this section only addresses the mix design problem.
HOT MIX ASPHALT PAVEMENT DESIGN GUIDEHOT MIX ASPHALT WHAT IS HOT MIX ASPHALT? Hot mix asphalt may be referred to by several names. In different sections of the state it may also be referred to as bituminous concrete,hot plant mix,asphalt concrete, blacktop or Superpave. Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total

CONCRETE MIXING RATIOS - Everything About ConcreteThe less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.
Asphalt Mix Design | Stonemont SolutionsStonemontQC is a tightly integrated application that allows users to manage all aspects of aggregate, asphalt, and concrete quality control mix design information. Asphalt mix component properties can be easily updated and pushed down to all mixes that use that component. Alternatively, asphalt mix components can be quickly substituted in all ...
