LT-AS0025 Vialit Plate (Binder Adhesion) Test Apparatus
LT-AS0025/1 Flat Steel Plates | 6 Adet
LT-AS0025/2 Steel Ball | 512gr
LT-AS0025/3 Hand-Operated Rubber-Lined Roller
The Vialit Plate (Binder Adhesion) Test Apparatus determines the adhesion performance between bituminous binders and aggregates using the Vialit plate impact method. The system helps laboratories evaluate the resistance of aggregate particles to detachment from the binder-coated surface.
- Vialit plate test method: Evaluates adhesion between bituminous binder and aggregate on prepared steel test plates.
- Controlled impact: A 512 g steel ball applies a repeatable impact to the prepared specimen.
- Standard specimen preparation: The rubber-lined hand roller presses aggregate particles uniformly onto the binder surface.
- Complete test set: Includes the test apparatus, steel plates, steel ball and rubber-lined roller.
- Six steel test plates: Supports routine preparation and comparison of multiple specimens.
- Stable test structure: The rigid metal frame provides consistent positioning during impact testing.
- Easy evaluation: Detached aggregate particles can be counted after impact to assess adhesion performance.
- Laboratory applications: Suitable for asphalt producers, road laboratories, universities and R&D centres.
- Standards compliance: Supports Vialit testing according to EN 12272-1 and EN 12272-3.

What Is a Vialit Plate Adhesion Test Apparatus?
The Vialit Plate Adhesion Test Apparatus determines the adhesion performance between bituminous binders and aggregates. The system uses the Vialit plate impact method to evaluate how strongly aggregate particles remain bonded to a binder-coated surface. Therefore, laboratories can assess the compatibility of materials intended for road surface applications.
Strong adhesion between binder and aggregate is important for the durability of surface treatments. The Vialit test also helps compare different binder and aggregate combinations before use.
How Is the Vialit Plate Impact Test Performed?
The operator first coats one side of a metal test plate with the selected bituminous binder. Aggregate particles are then distributed across the prepared surface.
A rubber-lined hand roller presses the particles into the binder and helps create a consistent specimen. The prepared plate is positioned on the test apparatus, which uses a stable supporting structure during impact.
A 512 g steel ball is then released onto the plate under controlled conditions. After impact, the operator evaluates the aggregate particles that have detached from the binder surface. Liya Test supplies the system with six steel plates, the steel ball and a hand-operated rubber-lined roller.
Controlled Impact Application
The drop mechanism allows the steel ball to strike the test plate under repeatable conditions. As a result, different specimens are exposed to comparable mechanical impact.
The rigid frame also keeps the test plate correctly positioned during the procedure. Consistent impact conditions help laboratories compare adhesion performance between different material combinations.
Specimen Preparation Equipment
The Vialit Plate Adhesion Test Apparatus includes the main components required for specimen preparation and testing. The six flat steel plates provide reusable test surfaces, while the rubber-lined roller helps press aggregates uniformly into the binder.
Proper specimen preparation is important because differences in aggregate distribution can influence the final result. Therefore, consistent preparation improves the repeatability of the adhesion assessment.
Laboratory Applications
The apparatus is suitable for asphalt producers, highway laboratories, universities, quality control centres and research facilities.
It is particularly useful for evaluating binder-aggregate adhesion in materials intended for road surface treatments. Laboratories can compare alternative binders and aggregate sources before selecting a suitable combination.
Vialit Testing According to EN 12272
The Vialit Plate Adhesion Test Apparatus supports testing associated with EN 12272-1 and EN 12272-3. Liya Test currently lists both standards for the LT-AS0025 product.
Overall, the LT-AS0025 Vialit Plate Adhesion Test Apparatus combines controlled impact, standard specimen preparation components and straightforward result evaluation. Therefore, laboratories can assess binder-aggregate adhesion under consistent and repeatable test conditions.
