#Bitumen is cutback by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen.
Cutback Bitumen is Bitumen that is dissolved in a solvent . Typical solvents include Naptha, gasoline and kerosene, white spirit etc. The type of solvent controls the curing time while the amount determines the viscosity of the Cutback Bitumen.
The advantage Cutbacks have over Emulsions is a much higher residual Bitumen percent, typically over 80% compares with over 40-65% for Bitumen emulsions. The result is more Bitumen left on the roadway after curing,

mastic #asphalt was developed in Germany in the 1960s. mastic asphalt has found use in Europe, Australia, the United States, and Canada as a durable asphalt surfacing option for residential streets and highways.

Mastic asphalt is produced for qualified road and bridge construction including corresponding structural waterproofing. Mastic asphalt flooring is also used in industrial and structural engineering.
The primary difference between mastic asphalt and asphalt concrete lies in each material's level of permeability. Asphalt concrete is fairly permeable under most conditions, allowing some water to seep through. Mastic versions are virtually waterproof, and can be used in applications where moisture-resistance is a primary concern.

The impervious quality of mastic asphalt can be attributed to its high concentration of #bitumen. Bitumen is a by-product of petroleum refinement, and is used as a binding agent in asphalt-based products. The bitumen content in mastic mixtures is typically double that found in concrete asphalt, which helps to bind the particles more closely together to keep water out.
This material offers many benefits to builders and homeowners. It is impervious to water and most chemicals, and is resistant to damage from pests and insects. It is also very strong and durable, and can be expected to last for decades in many common applications. Like other asphalt products, mastic mixtures are virtually fireproof, and can be easily recycled to avoid negative environmental impacts.
One of the primary disadvantages of this material is that is contains petroleum-based products in the form of #bitumen. Bitumen not only has a noxious odor in many cases, but may also produce hazardous fumes long after it is installed. Finally, like all asphalt products, mastic can be difficult to work with due to the high temperatures that must be maintained when spreading this material.

Bitumen Emulsions. #bitumen normally needs to be used or processed as liquid. There are basically three ways to make bitumen liquid:

Heat it.
Dissolve it in solvents. This has been done from the earliest times using Naptha. Principle uses of liquid bitumen produced with Naptha included mummification (Egypt) and waterproofing (Hanging Gardens of Babylon)
Emulsify it. At the beginning of the 1920’s, two English chemists, Hugh Alan Mackay and George Samuel Hay discovered and patented the first bitumen emulsion for use in road construction. This development allowed cold spraying. Since that time, the uses of bitumen emulsions have expanded, so that today, globally, more than 10 million tones of bitumen emulsions are now produced and applied.
The use of bitumen emulsions began in the early part of the 20th century. Today 5% to 10% of paving-grade bitumen is used in emulsified form, but the extent of emulsion usage varies widely between countries. More than 8 million tons of emulsions are produced worldwide and the United States is the world’s largest producer among the significant producers of bitumen emulsion: France, Mexico, and Brazil.

Performance Grade (PG) #bitumen is bitumen which is graded based on its performance at different temperatures. The LTPP has given certain algorithm to calculate the temperature of the pavement based on the temperature of the air above. From this, the highest and the lowest temperatures of the pavement is calculated and the bitumen that performs well in that temperature range is selected.

History
The Romans called it gwitu-men (pertaining to pitch) or pixtu-men (bubbling pitch), converted, after the barbarian invasions to #bitumen. The word passed into French, and then, after the Norman conquest of England in 1066, into English, where it was used interchangeably with tar for over a thousand years (though tar derives from coal, and bitumen from petroleum).

Bitumen is loder than the civilization of man kind. Although now associated with roads and produced in large, complex, modern refineries, natural bitumen was found long before this, among the desert dunes of Arabia.
Natural bitumen (often called tar sands or oil sands) and heavy oil differ from light oils by their high viscosity (resistance to flow) at reservoir temperatures, high density (low API gravity), and significant contents of nitrogen, oxygen, and sulfur compounds and heavy-metal contaminants. They resemble the residuum from the refining of light oil. Most heavy oil is found at the margins of geologic basins and is thought to be the residue of formerly light oil that has lost its light-molecular-weight components through degradation by bacteria, water-washing, and evaporation.

The basic idea in building a road or parking area for all-weather use by vehicles is to prepare a suitable subgrade or foundation¸ provide necessary drainage¸ and construct a pavement that will:
*have sufficient total thickness and internal strength to carry expected traffic loads;
*be sufficiently impermeable to prevent the penetration or internal accumulation of moisture; and
*have a top surface that is smooth¸ skid resistant¸ and resistant to wear¸ distortion¸ and deterioration by weather and deicing chemicals.
