Macadam is a type of road construction, pioneered by Scottish engineer John Loudon McAdam around 1820, in which single-sized crushed stone layers of small angular stones are placed in shallow lifts and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a binder to keep dust and stones together.

Single-sized aggregate layers of small stones, with a coating of binder as a cementing agent, are mixed in an open-structured macadam. A range of macadam materials for paving repair, bituminous and surface dressing. (3mm and 6mm sizes)

The invention relates to a high-modulus anti-oil-corrosion asphalt mixed material. The asphalt mixed material contains the following components: an aggregate with a particle size of 10mm-15mm, an aggregate with a particle size of 5mm-10mm, an aggregate with a particle size of 3mm-5mm, an aggregate with a particle size of 0-3mm, mineral powder with a particle size of 0-0.15mm, glass fiber, …

The resin bonded aggregate surfacing shall be capable of application on new and existing asphalt and Portland cement concrete surfaces. New asphalt surface shall be cured for a minimum of 30 days prior to installation. The resin bonded aggregate surfacing product shall: Be VOC compliant and lead free.

The asphalt distributor truck dispenses the asphalt emulsion, an aggregate spreader vehicle is required, a pneumatic roller (figure 9) is used, and a broom removes the excess chips. A slurry mixer and dispensing vehicle are needed to apply the slurry. Application The application is the same as the chip and the slurry seals stated earlier.

Asphalt Concrete (Bitmac) Asphalt Concrete is a layer of crushed rock, which relies on the mechanical interlock and internal friction of the aggregate to provide load-bearing strength. As the aggregate fraction is composed of a mix of various particle sizes, coarse medium and fine.

In free draining applications, a suitable geotextile should be placed at formation level (overlapping joints by 300mm), below the Drainage Aggregate sub-base. When the sub-base is designed to hold water an impermeable memebrane lining should be used.

Dense Bitumen Macadam Bitumen macadam in which the aggregates and filler are so graded as to form a close textured mixture, of low permeability, when spread and compacted. Dense Graded Mix An asphalt produced with aggregate that produces a continual grading. Usually low air voids as compared with open graded products.

For convenience, 6.3mm can be referred to as "6mm", and 31.5mm as "32mm".The ratio of D/d must not be less than 1.4. Aggregates are then designated as being either G C (coarse), G F (fine), or G A (all-in). Aggregate is classed as coarse if D is greater than 2mm, fine if D is less than 2mm, and all-in if D is less than 45mm and d is 0.

aggregate and the greater the amount of asphalt required to uniformly coat the particles. Conversely, because coarser mixes have less total aggregate surface area, they demand less asphalt. The relationship between aggregate surface area and optimum asphalt content is most pronounced where filler material (very fine aggregate fractions which pass
