Vacuum Pyknometer Test Set

Vacuum Pyknometer is used to determine the theoretical maximum specific gravity and density of noncompacted bituminous mixtures. Vacuum Penetrometer is used together with Sieve Shaker, Vacuum Pump and Vacuum Gauge to complete the test set. Percent air voids in compacted bituminous mixtures and the amount of bitumen absorbed by the aggregates can also be calculated with the test set. Vacuum Pyknometer is manufactured from transparent plastic and supplied complete with water trap and rubber tube.

Asphalt Bitumen Equipment

Execute Sampling of Asphalt Materials for Testing

Unit Standard No: 116773

NQF Level: 2

Credits: 10

Days: 3

Overview: Learners who are assessed as competent against this unit standard will be able to demonstrate competence to sample asphalt materials, under supervision, for standard laboratory testing.

This unit standard will enable learners to identify hazards and protective measures during asphalt sampling, identify and prepare resource for sampling, execute sampling, label and transport samples to the laboratory. (under supervision ) The unit standard contributes to the overall competence required of the construction materials tester.

The laboratory test results are used for quality control purposes during the construction and manufacturing processes as well as for final acceptance of the finished products.

Its contribution to socio-economic transformation is that learners would be able to undergo RPL-assessment and thereby receive recognition for previous learning and experience. The employability and career prospects of learners can therefore be enhanced by this qualification.

Previously disadvantaged individuals with this qualification can also progress to the level 4 qualification – this will enable them to start their own businesses supplying a construction materials testing service – a process that will accelerate economic transformation and give economic empowerment.
