These cutback grades can also be used in the process of manufacturing the pre-mix asphalt, which is used in patch repairs. Spray Sealing Cutback bitumen types are widely used in spraying sealing applications, particularly in low temperatures where they offer a much better initial stone retention because of their lower viscosity.

Emulsified asphalt is a suspension of asphalt in water by using an emulsifying agent which imposes an electric charge on asphalt particles so that they will join and cement together. Cutback asphalt is simply asphalt dissolved in petroleum. The purpose of adding emulsifying agent in water or petroleum is to reduce viscosity of asphalt in […]
Cutback Asphalt. Cutback asphalt is simply a combination of asphalt cement and petroleum solvent. Some are thin enough to be used as prime oil or tack, while others must be heated for use. Their uses included dust control, pavement maintenance, construction (chip seal) and cold mix patching.

It is also used to manufacture cutback bitumen, bitumen emulsions and modified bitumen. Class 320 is most commonly used to manufacture asphalt mixes while Class 600 is primarily used to manufacture extra heavy-duty asphalt pavements that need to endure substantial traffic loadings.
during mixing, water facilitates the even distribution of asphalt throughout the mass. the amount of moisture required for thorough distribution of cutback asphalt apparently increases as the amount of fine material in the soil increases. during the compaction phase the amount of water becomes important mainly because of its effect on density.
MC30. MC-30 is a type of medium curing cutback bitumen which is suitable for cold regions. It applies in road maintaining operations including tack coats and slurry seals. This type of liquid bitumen is constituted of a penetration grade bitumen and a petroleum based solvent.. Liquid bitumen is classified into four different types: RC, MC, SC and bitumen emulsion.
