Selection of an aggregate material for use in an Asphalt Concrete pavement depends on the availability, cost, and quality of the material, as well as the type of construction for which it is intended. To determine if an aggregate material is suitable for use in asphalt construc-tion, evaluate it in terms of the following properties: 1. Size and ...
Aggregate ” is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent of HMA and about 70 to 80 percent of portland cement concrete.
(either asphalt cement or asphalt emulsion) and cover aggregate. The aggregate used in each layer is of uniform size as practical and the maximum size aggregate for each successive layer is approximately one-half that of the previous layer. The two HMA mix types for low-volume pavements specified in Georgia are 4.75 and 9.5-Type I.
INTRODUCTION. Steel slag can be processed into a coarse or fine aggregate material for use in dense- and open-graded hot mix asphalt concrete pavements, (1,2,3) and in cold mix or surface treatment applications. (4) Proper processing of steel slag and special quality-control procedures are extremely important in selecting steel slag for use in asphalt paving mixes.
Use as aggregate is a recycling approach for managing granular soils and solids such as abrasive blasting media and petroleum contaminated soil. This approach involves using the waste as aggregate in asphalt. The waste can be used in hot mix or cold mix asphalt.
Asphalt concrete base (ACB), also called asphalt treated base (ATB), is a dense-graded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1). In addition to site paving benefits, ACB can be advantageous because it can provide: A waterproof barrier to prevent fines infiltration into the subgrade and pavement structure.
Why Use Asphalt Instead of Concrete? Though concrete once was used for paving roads, parking lots and other projects, asphalt paving is the preferred choice today. To begin to understand why asphalt paving is superior to concrete paving (also called cement paving), one should know how asphalt and concrete are made.

Apr 06, 2019· A hot mix asphalt (HMA), which is typically used for roads and parking lots, is as much as 95 percent asphalt aggregate by weight. The majority of aggregate in the mix is usually coarse, or large in size, followed by crushed stone and gravel. The remaining aggregate is composed of …
concrete and asphalt pavements The best aggregates to use for strength are crushed stone or crushed gravel. Crushed aggregate have irregular, angular particles that tend to interlock when compacted or consolidated. The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place.
HMA consists of two basic ingredients: aggregate and asphalt binder. 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. There are several different methods used to go

Apr 06, 2019· The largest source of recycled asphalt aggregate is slag from blast furnaces and steel furnaces. Recycled aggregate is often less expensive, because it can be made on site with portable crushers and aggregate washers. It also makes efficient use of old aggregate that would otherwise find its way into landfills.
The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.
Asphalt is a mixture of aggregate and binding agent. The binder is usually very hot when it’s combined with the aggregate. Pros pour the hot mixture over a level, gravel base before pressing and smoothing it with a steamroller. You can park or drive a car on it within 24 hours.
