is it possible to wet mix gradation from batch mix plant


Scrap Tires - User Guideline - Embankment or Fill

For both batch and drum-dryer plants the addition of rubber normally requires that the mixing time and temperature be increased. Batch plants require a dry mix cycle to ensure that the heated aggregate is mixed with the crumb rubber before the asphalt cement application. Mixtures should be produced at 149° C to 177° C (300° F to 350° F).

Reduced Mixing Time for Asphalt Concrete Mixes

however, these times now total 10 sec dry and 35 sec wet mixing, regardless of mix type being produced. Individual plant design and condition influence time requirements for adequate distribu­ tion and asphalt coating of aggregate particles, necessitating plant-by-plant testing to qualify for new reduced times.

Baghouse Fines

Baghouse dust can be fed directly from the baghouse into the plant mix or stored in a silo prior to use. The location where the baghouse fines are to be added to the plant mix depends on whether the plant is a batch mixing plant or a drum mix plant. In many cases, baghouse dust may be only a part of the mineral filler component of the mixture.

Fundamentals of Concrete

The batch plant operator must ensure that the amount of free-water in the mix does not vary from that called for in the mix design. Batch plant operators monitor aggregate moisture to determine if there is any free-water in the aggregate or if the aggregate is so dry that it will absorb water that is added to the mix.

As the mix time increases in a batch plant pugmill, the degree of aging of the asphalt binder also increases. For relatively short wet-mix times (28 to 35 seconds), the average asphalt cement will decrease 30 to 45 percent in penetration and increase roughly the same percent­ age in viscosity. For longer wet-mix times (up to 45 sec­

Drum-Mix Asphalt Plant

The mixing drum for which the plant is named is very similar in appearance to the batch plant dryer drum. The difference between the two is that in a drum-mix plant the aggregate is not only dried and heated within the drum, but it is also mixed with the asphalt cement.


An example of proportioning a mix design through use of this form is detailed in Table 3.1. The contractor establishes the initial parameters for a mix design and serves as the starting point for subsequent proportioning calculations. The initial step in proportioning the mix design is to calculate the water content per cubic yard of concrete.
