Bitumen K140: Benefits and Usage Guide

Bitumen k140

Understanding Bitumen K140

Bitumen K140 stands out as a rapid-setting cationic bitumen emulsion, composed of at least 40% bitumen and 60% water. This emulsified asphalt, meeting the standards of Malaysian Standard MS 1.61 (1994) and British Standard BS 434 Part 1: 1984 Class K1-40, offers a low viscosity that is primarily leveraged in tack coating applications. Its chocolate brown hue and free-flowing liquid state at room temperature make it easily recognizable and applicable.

Application and Uses of Bitumen K140

Tack Coating Excellence

Primarily utilized as a tack coat, Emulsion K1-40 plays a crucial role in establishing a strong bond between existing surfaces and overlays like hot rolled asphalt, macadam, and slurry seals. This functionality is pivotal in:

Minimizing spillage risks between courses.

Improving compaction during overlay laying, reducing pushing and sliding.

Versatile Functions

Beyond tack coating, K1-40 finds application in mist spraying and concrete curing operations. Its counterpart, K1-60, with a higher bitumen content, is typically employed in surface dressing, patching, retreading, and similar endeavors.

The Application Process

Optimal Coating Techniques

CARBONKIM Bitumen Emulsion K1-40, a cold-applied rapid-acting 40% cationic bitumen emulsion, forms a thin yet uniform bitumen film upon curing, enhancing the adhesive bond between bituminous overlays and existing surfaces. For optimal results, especially during overlaying with hot rolled asphalt or macadam, proper tack coating is strongly advised.

Best Practices for Application Bitumen K140

Prior to application, surfaces must be dry and devoid of contaminants like dust, oil, or grease. In hot weather conditions, surface dampening might be necessary to prevent rapid water loss from the emulsion during curing. Temperature ranges between 5°C and 35°C are ideal for application.

Safety Measures and Advantages

Safety First

Bitumen Emulsion K1-40 necessitates careful handling due to its flammable nature. Protective gear like clothing, gloves, and goggles is crucial to mitigate risks. Precautions against skin, eye, and inhalation contact are essential for safe usage.
