Bitumen Testing Equipment

Marshal test is extensively used in routine test programs for the paving jobs. The stability of the mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 600 °C. The flow is measured as the deformation in units of 0.25 mm between no load and maximum load carried by the specimen during stability test (flow value may also be measured by deformation units of 0.1 mm). This test attempts to get the optimum binder content for the aggregate mix type and traffic intensity. This is the test which helps us to draw Marshall Stability vs. % bitumen.

ASTM D6926, D5581; AASTHO T245 (only for UTAS-0071); BS-598

 

The UTAS-0670 and UTAS-0676 Marshall Manual Assemblies are used to prepare Marshall specimens manually.

The Compaction Assemblies consist of a Marshall Compaction Hammer and a Wooden Compaction Pedestal. The Pedestals are supplied complete with a steel plate, a mould holder and a hammer guide.

UTAS-0667 and UTAS-0668 Marshall Steel Blocks are used for initial heating of the foot of compaction hammer should be ordered separately.

 

 

The Reflux Extractor is used for the quantitative determination of bitumen in hot-mixed paving mixtures and pavement samples. The bitumen content is calculated by difference from the weight of extracted aggregates, moisture content and ash from an aliquot part of the extract.
 
The Reflux Extraction Test Sets are supplied complete with;

Cylindrical Glass Extractor Jar
Two Wire Mesh Cones with Interlocking Frames
Water Condenser with Inlet/Outlet Tubes
Filter Paper, 50 pcs./pack
Hot Plate
Iron Wire Gauze (-1830 with 0013, -1835 with -0020)
