2. Undertake the asphalt mix design
  • 2.1. Interpret and analyse the relevant data and identify the available viable options for the asphalt mix design
  • 2.2. Interpret and analyse relevant data and recommend the preferred option that best meets the required project outcomes
  • 2.3. Complete the design of the asphalt mix that safely, effectively and efficiently meets the required project outcomes
  • 2.4. Prepare a cost estimate of the execution of the designed asphalt mix
  • 2.5. Participate in the review of the asphalt mix design with peers and stakeholders
  • 2.6. Complete the documentation of the asphalt mix design
  • 2.7. Monitor and coordinate the progress of other team members involved in the design process
  • 2.8. Gain design approval
3. Finalise design processes of asphalt mix design
  • 3.1. Ensure filing of design records is completed
  • 3.2. Complete and submit design cost and other reporting
  • 3.3. Participate in performance review of the design process
  • 3.4. Seek client feedback and contribute to the verification of the design
  • 3.5. Close out all systems
4. Support and review the application of the asphalt mix design
  • 4.1. Provide clarification and advice to those applying the design
  • 4.2. Review the application of the design and recommend changes for the continuous improvements of asphalt mix designs
  • 4.3. Contribute to the validation of the design

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:
knowledge of the requirements, procedures and instructions for the completion of the design and documentation of asphalt mixes
implementation of procedures and techniques for the safe, effective and efficient completion of the design and documentation of asphalt mixes
the identification of the relevant information and scope of the work required to meet the required outcomes
the identification of viable options and the selection of the design and documentation of asphalt mixes that best meet the required outcomes
working with others to undertake and complete the design and documentation of asphalt mixes
consistent successful completion of the design and documentation of asphalt mixes
Context of and specific resources for assessment
This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.
The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.
Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.
Aboriginal people and other people from a non English speaking background may have second language issues.
Assessment of this competency requires typical resources normally used in a civil works environment. Selection and use of resources for particular worksites may differ due to site circumstances.
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Method of assessment
This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:
written and/or oral assessment of the candidate's required knowledge to apply in undertaking of the completion of the design and documentation of asphalt mixes
observed, documented and/or first hand testimonial evidence of the candidate's:
implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes
identification of the relevant information and scope of the work required to meet the required outcomes
identification of viable options and the selection of the design and documentation of asphalt mixes that best meet the required outcomes
consistently achieving the required outcomes
first hand testimonial and documentary evidence of the candidate's:
working with others to undertake and complete the design and documentation of asphalt mixes
provision of clear and timely required support and advice on the completion of the design and documentation of asphalt mixes
Guidance information for assessment
Consult the SkillsDMC User Guide for further information on assessment including access and equity issues.
