Vialit Adhesion Test Apparatus

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.
