The Vialit Adhesion Test Apparatus is used to assess the adhesion property of aggregates to bitumen. The method is a check on the adhesion of aggregates to be applied to the surface of wearing course rolled asphalt.
The apparatus consists of a:
- metal basement with three vertical pointed rods to hold the test plate
- vertical rod 50 cm high with a shot at the upper end for the steel ball to drop
- 512 g steel ball
- supply of 6 metal test plates
- hand operated rubber lined roller with lead shots ballast.
How it works
- The test plate, coated by bitumen on one face, and spread with aggregate chippings (in a manner compatible with relevant standards) is rolled and then placed on the base.
- The steel ball drops three times from the shot and the loose chippings are counted and checked.
