Application of different bitumen in road construction!
Although bitumen sounds very technical, we usually refer to it as asphalt. However, bitumen coating for concrete is frequently utilized for covering roadways in addition to offering a waterproofing option. The many types of bitumen coating used in road building are highlighted here.
Cutback bitumen: Bitumen is typically heated to decrease viscosity. In some circumstances, liquid binders like cutback bitumen are preferred. To reduce the bitumen's viscosity in cutback bitumen, an appropriate solvent is needed. For constructing and maintaining bituminous roads in cold weather, cutback bitumen is employed. Cutback bitumen comes in a variety of forms, including rapid curing (RC), medium curing (MC), and delayed curing (SC).
Bitumen emulsion: Bitumen is suspended in a finely split state in an aqueous medium and stabilized by appropriate material to create a liquid product known as a bitumen emulsion. The emulsion contains around 60% bitumen and the rest is water. When the emulsion is placed on the road, it degrades, releasing water as the mixture begins to set. The bitumen grade affects how long it takes to set. There are three different kinds of bituminous emulsions: Rapid setting (RS), Medium setting (MS), and Slow setting (SC).
Bituminous primers: The distillate in bitumen primer is absorbed by the road surface on which it is applied. As a result, the surface's porosity affects the absorption. On stabilized sur and water-bound macadam base courses, bitumen primers are helpful. On road construction sites, bituminous primers are often made by combining petroleum distillate with penetration bitumen.
Modified bitumen: The characteristics of bitumen and bituminous mixtures can be enhanced by specific additions or a combination of additives referred to as bitumen modifiers. Modified bitumen is bitumen that has been treated with various modifiers. Based on the demands of extreme climate fluctuations, polymer-modified bitumen (PMB) or crumb rubber-modified bitumen (CRMB) should only be used in the wearing course. It should be highlighted at tight temperature control during construction is essential for the operation of PMB and CRMB. The following are some benefits of utilizing modified bitumen.
Less prone to daily and seasonal temperature fluctuations
Increased resistance to deformation when the pavement is high
Improved aging resistance qualities
Improved bonding between the aggregates and the binder
Avoiding reflective and cracked cracking
The mix type and structure have an impact on the bitumen's desired qualities. The following qualities are often desired in bitumen.
The bitumen shouldn't be very sensitive to temperature changes; it shouldn't melt or become unstable in the hottest weather, and it shouldn't fracture in the coldest weather if it gets too brittle.
When combining and compacting, the bitumen's viscosity should be sufficient. This can be accomplished by heating the bitumen and aggregates before mixing, using cutbacks or emulsions of acceptable grades, or both.
The bitumen and aggregates used in the mix should have sufficient affinity and adhesion
