About Stripping Value Apparatus

Stripping Value Apparatus:

Micro Teknik

A circular tray rotates in a vertical plane at a rate of approximately 100 r.p.m. by an eletrical geared motor.
4 bottles of approximately 400 cc are mounted on this circular tray at an angle of 90 to each other with their mouths towards centre of the tray.
A time switch is provided.
Suitable for operation on volts A.C. single phase.

Purpose and Application

The Stripping Value Apparatus is crucial in asphalt testing laboratories to assess how well bitumen adheres to aggregates when exposed to water. This test is particularly significant in evaluating the potential durability of road construction materials, ensuring optimum performance in Indian climatic conditions. Reliable assessment minimizes pavement failure, thereby supporting long-lasting road infrastructure.

Key Features and Construction

The apparatus consists of a robust mild steel frame, a 1-liter borosilicate glass beaker, and metallic specimen rings made from gun metal or brass. Designed for manual operation, it allows easy inspection of up to six aggregate specimens using analog (visual) observation. The setup facilitates even heat distribution using standard laboratory heating methods for accurate and consistent results.

Testing Method and Usage

This apparatus employs the hot water immersion method, where aggregate specimens coated in bitumen are immersed in boiling water. The percentage of bitumen stripped off is then assessed visually by the operator. External heating (Bunsen burner or electrical heater) enables temperature control up to boiling point, ensuring standardized and repeatable testing conditions. Manual operation allows flexibility in laboratory and contractor environments.

FAQs of Stripping Value Apparatus:

Q: How is the Stripping Value Apparatus used for asphalt testing?

A: The apparatus is used by placing six aggregate specimens coated with bitumen into specimen rings and immersing them in a borosilicate glass beaker filled with water. The beaker is then heated to boiling using an external source. After a set duration, visual observation is performed to estimate the percentage of bitumen that has stripped from the aggregate surfaces.

Q: What standards does this apparatus comply with?

A: The Stripping Value Apparatus is designed to conform with IS:6241 and ASTM D1664 standards (or their equivalents), which specify procedures for evaluating the stripping value of aggregates in bituminous mixes.

Q: When should the stripping value test be performed during asphalt quality control?

A: This test is typically conducted during laboratory evaluation of aggregates and bitumen before construction, as part of routine quality checks, or when monitoring the potential for moisture damage in pavement materials.

Q: Where is this equipment commonly used?

A: The apparatus is widely used in asphalt quality control laboratories, testing centers, and by civil engineering consultants involved in road construction projects. It is also distributed and supplied by manufacturers, exporters, and traders across India.

Q: What is the process to heat the aggregates in this apparatus?

A: The apparatus employs a 1-liter borosilicate glass beaker positioned on a mild steel frame, heated with an external Bunsen burner or electrical heater (not supplied). The specimens are immersed in water and brought up to boiling temperature, ensuring uniform and controlled heating for accurate test results.

Q: What are the main benefits of using a manual Stripping Value Apparatus?

A: Manual operation allows for flexible and straightforward testing without the need for specialized power sources. It enables operators to visually assess stripping, encouraging hands-on training and skill development while ensuring reliable aggregate performance evaluation.

Q: How accurate are the results from this apparatus?

A: The accuracy depends primarily on the operators ability to visually estimate the percentage of stripped bitumen. While manual and subjective, adherence to standardized test methods and routine operator training can enhance consistency and reliability.
