Dynamic vapor sorption (DVS) |
Dynamic vapor sorption (DVS) is a technique that measures how quickly and how much of a solvent is absorbed by a sample: such as dry aggregate filler absorbing water. It does this by varying the vapor concentration surrounding the sample and measuring the change in mass which this produces. |

| |
Force Ductilometer
|
Ductility is measured by the distance to which a sample will elongate before breaking when two ends of a specimen briquette are pulled apart at a specified speed and at a specified temperature. Our ductilometer is also able to measure the resulting realtime force caused by the specified rate of pull until the bitumen sample breaks.

The Hollow Cylinder Apparatus (HCA) has the potential to closely simulate the complex in-situ pavement stress regime induced by moving wheel loads. The equipment has the capability to generate complimentary shear stresses to the tested specimen, which allows the study of material anisotropy and the principle stress rotation effects. |
 |
Immersion Wheel Tracker |
A dual arm immersion wheel tracker which is used to evaluate the resistance to rutting and moisture susceptibility of asphalt mixtures at varying temperatures.
|
 |
Marshall Compactor |
Used for the manufacture of small asphalt cores. The Marshall compactor drops a known weight for a predetermined number of blows onto a hot asphalt mixture to form a core.

Servo-hydrauic Tension-Compression Machine
|
A Servo-Hydraulic mechanical testing machine capable of testing in both compression, or tension modes using loads of up to 150KN.
|
 |
Laboratory Roller Compactors |
Used to compact laboratory asphalt samples of 305mm by 305mm or 500mm by 500mm square at varying temperatures.
|
 |
Micro Calorimeter |
This is used to determine the changes in energy of a system by measuring the heat exchanged with the surroundings during an exothermic, or endothermic reaction. |
 |
Nottingham Asphalt Tester /NU-14 |
For the measurement of mechanical properties of bituminous materials, the NAT/NU14 can be configured in various ways to provide the user with a convenient method of measuring stiffness modulus and fatigue strength of bituminous material using the repeated load indirect tensile test and assessing resistance to permanent deformation.

Pressure Aging Apparatus for Asphalts (PAV)
|
The PAV is used to subject bitumen or bituminous materials to pressures of up to 2.45MPa and temperatures up to 148°C. This is used to simulate the in-service oxidative ageing that occurs in asphalt binders during pavement service.
|
| |
pH and Conductivity Testers for Leachate
|
Leachate is any liquid that, having passed through matter, extracts solutes, suspended solids or any other component of the material through which it has passed. We can test these components using various different techniques.
