A Technical Outlook of Asphalt Constructions Paving
Laymen oftentimes consider Asphalt Constructions Paving as the overlay of asphalt on concrete pavements and Bitumen Driveways made using Portland cement. The term concrete however refers to any composite material of mineral aggregates like crushed gravel or small stones. These are bonded together using a binder like asphalt, Portland cement or epoxy utilized within the construction industry for airports, road surfaces, parking lots and like pavements. Asphalt concrete can as well be applied as roofing overlay with aim of minimizing, if not completely eradicating, seepage and leaks.
Genesis of Concreting Applications
Concreting services began with Portland cement as the binding material which eventually lent it the popular reference of “concrete” getting equated to “portland cement”. Engineers and scientists would then discover with advancing technology that using asphalt constructions paving as an overlay on Portland cement concrete pavement offered a much better option for a number of good reasons as follows:
- increased durability of the surface implied extending the pavement’s lifespan
- minimized wear and tear of tire offered smoother ride due to its softer surface
- reduced “roadway noise” along with better mileage efficiency
- higher braking efficiency afford safety to motorists
The use of blacktop as paving for asphalt constructions is well-known in North America and has spread rapidly to other nations, as it undergoes greater improvement through innovative technologies. At least six formulations of asphalt concrete are available today for instance, which the Asphalt Paving Services Melbourne has can apply for diverse types and purposes of paving construction.
Hot Mix Asphalt
Hot Mix Asphalt Concrete (HMA or HMAC) is capable of withstanding “heavy beating.” As such the companies for driveway asphalting Melbourne has today utilize it most commonly when working on “highly trafficked” pavements which include airfields and airport runways, race tracks and major highways. Just as its name suggests, this kind requires softening of asphalt binder to be done using heat, before mixing it with well-dried aggregate at either 300°F for virgin asphalt or at 330 F for the polymer-treated type of asphalt.
Warm Mix Asphalt
Warm Mix Asphalt (WMA) Concrete applied on Bitumen Driveways is produced at lower mixing temperatures owing to addition of asphalt emulsions, zeolites or waxes, which consequently decreases need for fossil fuel. The lower laying temperature facilitates a faster seasoning time-frame, which hastens the availability of the pavement for use.
Cold Mix Asphalt Concrete
Cold Mix Asphalt Concrete is utilized as a patching material or for Asphalt Carparks for example or traffic service road applications of less form. This variety is a “cold” version of HMAC that involves emulsification of asphalt in soapified water.
Cut-back asphalt concrete comes as a type of formulation which for environmental reasons is seldom applied since it involves using kerosene for softening asphalt as opposed to heating.
Mastic Asphalt Concrete
Mastic Asphalt Concrete requires hard asphalt to be cooked within a mixer for between 6 and 8 hours. Seasoned layers are able to lay the formulation either by hand or machine at 20-30 mm thickness on Bitumen Driveways and foot paths and at 10 mm for roofs and flooring.

Natural Asphalt Concrete
Natural Asphalt Concrete is a somewhat natural formulation that results from upsurge of bitumen from within porous sedimentary rocks, found in certain sections of the earth. This formulation is preferred better, where applicable, owing to its harmlessness to the ecosystem.
