Benkelman Beam Apparatus – For Bitumen Testing

The Benkelman Beam Apparatus is a precision instrument used to measure the deflection of flexible pavements under moving wheel loads. This bitumen testing equipment is essential for evaluating the structural performance and rebound deflection of asphalt and bituminous road surfaces. Designed as per ASTM D4694, ASTM D4695, and IRC:81-1997 standards, it provides accurate and repeatable measurements for pavement evaluation and maintenance planning.

The apparatus features a lightweight yet sturdy beam assembly with precision pivoting and a sensitive dial gauge for accurate readings. Ideal for road construction quality control, highway research, and pavement performance analysis, the Benkelman Beam Apparatus ensures reliable results in both laboratory and field conditions.

✅ Key Features:

• Conforms to ASTM and IRC standards

• Lightweight, rigid aluminum beam construction

• Sensitive dial gauge for accurate deflection measurement

• Easy to assemble and transport

• Suitable for field testing of flexible pavements
