Bitumen emulsion is a mixture of bitumen with water, typically stabilized by an emulsifier. This liquid substance offers distinct properties that make it critical in various road construction applications. One of its primary advantages is its ease of application, as it can be easily sprayed and distributed using conventional tools. Bitumen emulsion also exhibits excellent adhesion with aggregates, ensuring a strong road surface. Its ability to set quickly also contributes to its efficiency in construction projects.
Applications of bitumen emulsion in road construction are wide-ranging. It is commonly used as a cement for pavement layers, providing stability to the road surface. Additionally, it serves as a barrier against water penetration, preventing damage caused by moisture. Furthermore, bitumen emulsion is employed in various other applications such as crack sealing, shoulder construction, and surface treatments.
