Therefore, they are not able to improve the interfacial bonding strength between acidic aggregates and asphalt after mixing and construction.
4) Voids Filled with Asphalt (VFA) 5) Binder Content Before mix properties are discussed in detail, the Technician is required to understand that paving mix properties are most affected by volume and not weight; however, production and testing of HMA is by weight. An example of the difference between weight and volume of HMA is given in Figure 4-1.
Sep 28, 2010 · Not too long ago, some smart people in the asphalt-paving industry got to thinking about the potential benefits of reducing the temperature at which asphalt mixes are produced and placed. Instead of conventional hot-mix, which typically is loaded into trucks at the plant in the temperature range of 280F to 325F, why not a "warm-mix" that could be produced at temperatures in the range of 180F ...
New asphalt pavements must be allowed to cure at least 90 days in hot weather. Perform a water break free test to confirm that the surface oils have dissipated. Spread water on the pavement, and if the water does not bead, pavement is ready for sealcoating. Not recommended for steeply inclined surfaces, as they may become slippery when wet.

The mix remains in the mixing portion of the drum for much longer periods of time (maybe 2 to 3 minutes) than in the pugmill of a batch plant, so the aggregate particles get very well coated. Keep in mind that we are not as concerned about oxidation in drum mixes as the mixing portion of the drum mixer is essentially an oxygen-free atmosphere.
