What is raveling of asphalt pavement joints?
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.
What is the difference between asphalt and concrete?
"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
What are some of the ingredients used by an asphalt plant to make asphalt?
Asphalt basically consists of 2 types of components: various kinds of aggregates in different size distributions providing the load bearing performance and bitumen as the binder assuring mechanical and thermal flexibility.
Is asphalt cement primarily made from bituminous coal tar or from petroleum byproduct?
True asphalt cement is made ONLY of petroleum byproduct, and may have varying levels of volatiles still present, but should never include any coal tar, as that is an entirely different binder. The two do have many similarities, though, particularly that they are both thermoplastic binders. But the main answer is that asphalt DOES NOT contain bituminous coal tar.
Name the petroleum product used for surfacing roads?
Asphalt, also known as bitumen, is the sticky, black and highly viscous liquid or semi-solid present in most crude petroleums and in some natural deposits; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used.The 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.

What is density of asphalt cement?
the bitumen binder is about the same as water (at 20 Celsius) with 6% binder asphalt cement is 2.423 that of water
What is the problem if use the wearing course in the place of binder course?
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.
EFFECT of OIL on ASPHALT?
Depends on type and quantity of oil, but it tends to dissolve the bitumen binder and so destroy the asphalt.
Please Convert 509 tons of asphalt concrete binder course to cubic meter?
To convert 509 tons of asphalt concrete binder course to cubic meters, you need to know the density of the material. The density of asphalt concrete binder course can vary, but a common value is around 2.2 tons per cubic meter. Using this value, 509 tons would be approximately 231.36 cubic meters.

Is kerosene good to mix with ashphalt?
No, kerosene is not recommended to be mixed with asphalt. It can degrade the asphalt binder, affecting the overall performance and durability of the asphalt mixture. It is important to use recommended additives and mixtures for asphalt to maintain its quality.
Is an asphalt road homogenous or heterogenous?
An asphalt road is considered heterogeneous because it is made up of various components such as aggregates, binder, and additives that are mixed together to form the final product.
What is an asphalt emulsion?
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.
