What is an asphalt drum mixer?

The Use and Function of an Asphalt Drum Mix Plant - Bright ...

The Asphalt Drum Mix Plant ensures that the asphalt produced should be of proper specifications and suitable for pavement. Asphalt has different functional properties that can affect the conditions on the road, like tire wear, brake efficiency, and road noise. The rolling friction also converts kinetic energy into sound waves. Therefore, the temperature, feed rate, and drum mixing have to be carefully monitored to produce asphalt of the correct specifications.

What Equipment is Used for Asphalt Paving?

Hot Mix Asphalt is loaded in the front, carried to the rear by a set of flight feeders, spread out by a set of augers, then leveled and compacted by a screed. This set of functions can be divided into two main systems:

FUNCTIONS OF FILLERS IN BITUMINOUS MIXES

A FILLER DEFINED AS THAT FRACTION OF AN INERT MINERAL DUST PASSING THE 200-MESH SIEVE IN A BITUMINOUS MIXTURE CAN PERFORM SEVERAL FUNCTIONS. ONE FUNCTION IS THAT OF FILLING VOIDS IN COARSER AGGREGATES, WHICH INCREASES THE DENSITY, STABILITY, AND TOUGHNESS OF A CONVENTIONAL BITUMINOUS PAVING MIXTURE. ANOTHER, IS THE CREATION OF A FILLER-ASPHALT MASTIC IN WHICH THE PARTICLES OF DUST EITHER MAY BE INDIVIDUALLY COATED WITH ASPHALT OR ARE INCORPORATED INTO THE ASPHALT IN MECHANICAL AND COLLOIDAL ...

DRYER DRUM MIXER - Astec, Inc.

incorporating large percentages of recycle asphalt and various other recycle products will have to be equal to that of virgin mix. Both the old and new liquid asphalt will have to be distributed uniformly throughout the mix. This will require making mixes 20 to 30° F hotter than usual to produce a mix viscosity that will allow

Asphalt Drum Mix Plant - High Mixing Efficiency And Simple ...

Asphalt drum mix plant can achieve the continuous mixing of bitumen, so it also called continuous mix asphalt plant.Different from other types of asphalt mixing plant, the drying and mixing of asphalt drum mix plant is carried out in one machine, namely, drying drum.

Asphalt Mixing Plant - Long Service and High Efficiency

Asphalt mixing plant is a kind of equipment to mix the proportioned aggregates into the asphalt mixture under the specified temperature. And its main application is to produce asphalt, modified asphalt mixture, colored asphalt mixture and meet the requirements of highway construction, classified highway construction, urban road construction, parking lots, airport construction and port ...

The mix­ ing time for blending of the asphalt cement with the ag­ gregate should be no more than that needed to com­ pletely coat the aggregate particles with a thin film of the asphalt cement material—usually in the ...

HOT MIX ASPHALT – McAsphalt

Hot mix asphalt (HMA) consists of a combination of aggregate uniformly mixed and coated with asphalt cement. To dry the aggregates and to obtain sufficient fluidity of asphalt cement for proper mixing and workability, both the aggregate and asphalt must be heated prior to mixing—hence the term “hot mix.”

Portable Asphalt Mixing Plant - Convenient Small And Portable ...

Compositions of portable asphalt mixing plant. Portable asphalt batch plant mainly consists of a cold aggregate batching system, drying system, burning system, hot aggregate elevator, vibrating screen system, hot aggregate storage bin, weighing system, asphalt supply system, filler supply system, dust collecting system, mixing system, finished product storage bin, electric control system.

Chapter 2 Asphalt and Asphalt Paving Materials

ent names: hot mix asphalt, plant mix, bituminous mix, bituminous concrete, and many others. It is a combination of two primary ingredients - aggregates and asphalt cement. The aggr egates total 90 to 95 per cent of the total mixture by weight. They are mixed with 5 to 10 percent asphalt cement to form Asphalt Concrete.

Glossary of Terms | Asphalt Institute

Asphalt Emulsion Mix (Cold): A mixture of unheated mineral aggregate and emulsified (or cutback) asphalt binder. It can be plant-mixed or mixed in-place. Asphalt Emulsion Mix (Warm): A mixture of asphalt emulsion and mineral aggregate usually prepared in a conventional hot mix asphalt plant at a temperature less than 95°C (200°F). It is ...

Asphalt concrete - Wikipedia

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams.

» Asphalt Concrete

Asphalt/Asphalt Concrete mixes are designed for specific functions, characteristics, attributes, performance, location and function in the pavement structure. For example, asphalt surface mixes have an entirely different function in the pavement structure than base asphalt mixes and are therefore designed differently.

HMA Mix Design Fundamentals - Pavement Interactive

HMA mix design is the process of determining what aggregate to use, what asphalt binder to use and what the optimum combination of these two ingredients ought to be. When aggregate and asphalt binder are combined to produce a homogenous substance, that substance, HMA, takes on new physical properties that are related to but not identical to the ...

Asphalt Cement - an overview | ScienceDirect Topics

For example, the laboratory mixing of asphalt and aggregate is accomplished either by hand or by means of a mechanical mixer, and mixing efficiency and mixing times may vary. After mixing, the loose mix is aged to allow for asphalt absorption and, presumably, some additional stiffening.

Mix Types - Pavement Interactive

The open gradation creates pores in the mix, which are essential to the mix’s proper function. Anything that tends to clog these pores, such as low-speed traffic, excessive dirt on the roadway can degrade performance. Suggested Reading. National Asphalt Pavement Association (NAPA). (1995). Thin Hot Mix Asphalt Surfacings, Information Series 110.

Volumetrics in Asphalt Mixtures

asphalt content of a mix is highly dependent on aggregate characteristics such as gradation and absorptiveness. Aggregate gradation is directly related to optimum asphalt content. The finer the mix gradation, the larger the total surface area of the aggregate and the greater the amount of asphalt required to uniformly coat the particles.

* mixer with a capacity of approximately 100 tons per day. * discontinuous mixer, whose capacity is approximately 200 to 800 tons per day. * continuous mixer, whose capacity is greater than 500 tons per day. The source of aggregates depends on the use of cold asphalt: materials may be calcareous, silico-calcareous or from solid rock.
