works effectively with others to undertake and complete the compacting of asphalt with rollers that meets all of the required outcomes including:

organising work activities to meet all task requirements

communicating clearly and concisely with others to receive and clarify work instructions

using a range of communication techniques and systems such as signage to advise others of work activity and exclusion zone

demonstrates completion of compacting asphalt with rollers that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

identifying, reporting and recording hazards and risks

compacting a minimum of 2000m2 of asphalt to the determined pattern, the measured density, with the minimum number of passes specified and to job specifications for five projects, with at least one project under 50mm thick and one project over 50mm thick

a minimum of three longitudinal joints of 100 metres each and two transfer joints to be matched


Evidence of Knowledge

The candidate must demonstrate knowledge of compacting asphalt with rollers through:

applying legislative, organisational and site requirements and procedures:

site and equipment safety requirements

asphalt compacting techniques

asphalt paving operations

asphalt strength and performance characteristics

edge and joint treatments

safe operating techniques in all terrain

housekeeping

equipment types, characteristics, technical capabilities and limitations

applying and monitoring operational, maintenance and basic diagnostic procedures

applying site isolation and traffic control responsibilities and authorities

applying processes for the calculation of material uniformity and travel speed

safety data sheets and materials handling methods

monitoring project quality requirements

preparing and/or implementing JSAs/JSEA/safe work method statements


Assessment Conditions

An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,

this unit must be assessed in the context of this sector’s work environment; and,

this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,

assessment may be conducted in conjunction with the assessment of other Units of Competency; and,

assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,

assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,

where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,

assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:

Industry sector

AQF** Level

Required assessor or Industry subject matter expert experience

Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction

1

1 Year

2

2 Years

Drilling, Coal Mining and Extractive (Quarrying)

3-6

3 Years

Metalliferous Mining and Civil Construction

3-6

5 Years

Other sectors

Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation.

*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
