The Asphalt density is missing.
An asphalt emulsion is a mixture of asphalt and water that is combined to form a liquid substance. It is commonly used in road construction and maintenance as a binder or adhesive for asphalt pavement. The emulsion allows for easier handling and application of the asphalt and helps improve the overall performance and durability of the pavement.
A bituminous road is a road that has been covered with bitumen. If this is wrong, could I please have the correct answer. A bitumen road is different from tar road. bitumen is extracted from crude oil. since the bitumen is used as a binder this road is called bituminous road. if tar is used as a binder then it is called tar road.
"Bitumen" redirects here. For naturally occurring bituminous sands used for petroleum productionThe terms bitumen and asphalt are mostly interchangeable, except where asphalt is used as an abbreviation for asphalt concreteThe primary use 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.The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Natural deposits terminology also sometimes uses the word bitumen,The substance is completely soluble in carbon disulfide, and composed primarily of a mixture of highly condensed polycyclic aromatic hydrocarbons; it is most commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase (though there is some disagreement amongst chemists regarding its structure). One writer stated although a "considerable amount of work has been done on the composition of asphalt, it is exceedingly difficult to separate individual hydrocarbon in pure form",[8] and "it is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large".[9]Most natural bitumens contain sulfur and several heavy metals, such as nickel, vanadium, lead, chromium, mercury, arsenic, selenium, and other toxic elements.[citation needed] Bitumens can provide good preservation of plants and animal fossils.
yes
it is a layer in binder coarse
Hot-mix asphalt concrete is a mixture of aggregate (crushed stone, gravel and sand) and asphalt binder. asphalt is a hydrocarbon mixture which makes the road.
the bitumen binder is about the same as water (at 20 Celsius) with 6% binder asphalt cement is 2.423 that of water
depends what the substances are, probably a suspension.

"Asphalt" the paving material is more properly called asphaltic concrete. It's gravel held together by a binder of a tarry substance extracted from crude oil known as bitumen. Bitumen is also itself sometimes called asphalt. "Concrete" is a type of building material that basically consists of rocks (gravel) combined with cement and usually sand. the crisp like the firt jsk; <:O :) >:l
Asphalt binder course is an intermediate course between a base course and an asphalt surface course. The binder course is usually a coarse-graded aggregate Asphalt Concrete containing little or no mineral matter passing through a No. 200 sieve. The surface course is one or more layers of a pavement structure designed to accommodate the traffic load, the top layer of which resists skidding, traffic abrasion, and the disintegrating effects of climate. The top layer is sometimes called the wearing course. This course is very fine in gradient compared to binder.
Depends on type and quantity of oil, but it tends to dissolve the bitumen binder and so destroy the asphalt.
The primary use of asphalt/bitumen 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.
Raveling is loss of pavement material from the surface downward and is caused by the loss of asphalt binder (deterioration), ultraviolet exposure, traffic frequency, weather conditions, asphalt mix design, and compaction of the asphalt during construction. As the asphalt binder in the pavement wears away, the appearance starts to turn grayish from the fresh, black look of new asphalt. Also, as the binder wears away, aggregate particles begin to break away. This begins with fine aggregate particles breaking away and, consequently, exposing the coarse aggregate.
cement is the binder for concrete like glue with out it you have mud with rocks
The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
Roman concrete consisted of the same basic elements as present day concrete which is an aggregate and a binder. For the aggregate the Romans used pulverized rubble, broken tiles and rock. A volcanic debris called "pit sand" was also used. For the binder, gypsum and lime was used.
