This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Learners who are assessed as competent against this unit standard will be able to demonstrate competence in the executing of standard laboratory testing, under supervision, pertaining to asphalt materials used in the Construction Industry.

This unit standard will enable learners to identify hazards and protective measures during asphalt testing, prepare asphalt samples for testing, identify and apply the required apparatus during testing, take readings and record these. (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. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING
