STRIPPING VALUE APPARATUS AZA0943
The AZA0943 Stripping Value Apparatus from Azalab is a precision laboratory instrument designed to evaluate the adhesion characteristics of bitumen-coated aggregates when subjected to water immersion. This test is critical in assessing the resistance of aggregates to stripping, a major cause of premature pavement failure due to moisture ingress.
The apparatus is widely used in road construction quality control laboratories, civil engineering departments, research institutions, and third-party testing facilities. It fully complies with ASTM D1664 and IS 6241, ensuring acceptance across both international and Indian testing frameworks.
Description
Importance of the Stripping Value Test
Moisture damage is one of the leading causes of deterioration in bituminous pavements. The stripping value test determines the ability of bitumen to retain its bond with aggregates under adverse water and temperature conditions.
Using the AZA0943, bitumen-coated aggregate samples are immersed in hot water under controlled conditions. After immersion, the aggregates are visually examined to assess the percentage of bitumen film stripped from the aggregate surface. This qualitative evaluation plays a vital role in:
-
Selecting suitable aggregates
-
Designing durable bituminous mixes
-
Evaluating the need for anti-stripping agents or additives
-
Ensuring long-term pavement performance
Robust Design & Efficient Operation
The AZA0943 Stripping Value Apparatus features a thermostatically controlled, double-walled stainless steel water bath capable of maintaining temperatures up to 100°C, simulating extreme service conditions. The system includes six heat-resistant glass beakers, suspended uniformly on a specially designed stand to ensure consistent heating and immersion.
The apparatus is engineered for laboratory safety, durability, and ease of operation, with corrosion-resistant construction and a compact footprint suitable for routine testing.
