Slurry Seal Testing

80-B0193
Slurry Seal is a mixture of water, asphalt emulsion, additives and fine crushed aggregate that is spread on the surface of a road as treatment to improve its friction properties. This section includes a range of equipment to evaluate the mechanical properties of Slurry Seals, including cohesion, consistency and resistance to abrasion by using a planetary mechanical stirrer.

Cohesion Tester

For determining the proper consistency (mix design) for a slurry seal mixture.

Standards ASTM D3910 EN 12274-4

80-B0193
Description

 

For determining the proper consistency (mix design) for a slurry seal mixture. Pneumatically operated, it consists of a double acting, double end-rod pneumatic cylinder fit in a frame, which houses the pressure gauge and valves. A hand torque tester is also supplied. The tester has to be completed with the suitable Square mould. See accessories.

  • Weight approx.: 20 kg

Vialit Adhesion Test Apparatus

Used to assess the adhesion property of aggregates to bitumen.

Standards EN 12272-3

80-B0178/A
Description

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; a 512 g steel ball; a supply of 6 metal test plates; a hand operated rubber lined roller with lead shots ballast. The test plate, coated by bitumen on one face and spread by the aggregate chippings in a standard way is rolled by the roller and then placed on the three-point support of the basement.
The steel ball drops three times from the shot and the loose chippings are counted and checked.
