Operating and controlling operations of road plant, machinery or equipment for laying high friction surfacing in the workplace
This unit focuses on the competent operation and control of specialized road plant and machinery used to apply high friction surfacing materials, a critical process for enhancing skid resistance on roads. Learners must demonstrate the ability to interpret work instructions, organize tasks with colleagues, and comply with health and safety regulations while maintaining productivity and quality standards. Practical application includes selecting appropriate resources, minimizing environmental damage, and ensuring the finished surfacing meets contract specifications within deadlines.
Assessment criteria
Topic Overview
The GQA LEVEL 2 NVQ DIPLOMA IN ROADBUILDING AND MAINTENANCE (CONSTRUCTION) is a vocational qualification designed for individuals working in the highways sector. It covers the practical skills and knowledge required to construct, maintain, and repair roads, footpaths, and other paved areas. This diploma is part of the Construction & Building Services suite and is recognised by employers across the UK, making it essential for those seeking a career as a roadworker or highway maintenance operative.
The qualification focuses on key areas such as interpreting drawings, preparing work areas, laying kerbs and channels, and using materials like asphalt and concrete. It also emphasises health and safety regulations, including risk assessments and safe manual handling. By completing this NVQ, students demonstrate competence in real-world tasks, which is critical for ensuring road safety and durability. This diploma aligns with the Construction Skills Certification Scheme (CSCS), helping learners gain the necessary cards for site access.
Understanding this topic is vital because the UK's road network is a critical infrastructure asset. Proper roadbuilding and maintenance reduce accidents, improve traffic flow, and extend the lifespan of surfaces. This qualification equips learners with the skills to contribute to these outcomes, whether working on local roads, motorways, or cycle paths. It also provides a foundation for progression to Level 3 qualifications in highways maintenance or civil engineering.
Key Concepts
Core ideas you must understand for this topic
- →Health and Safety Compliance: Understanding the Health and Safety at Work Act 1974, risk assessments, and method statements (RAMS) is non-negotiable. You must know how to use personal protective equipment (PPE) like hard hats, high-visibility clothing, and steel-toe boots, as well as traffic management measures such as temporary traffic lights and cones.
- →Material Properties and Handling: Know the differences between asphalt, concrete, and tarmac, including their uses for base courses, binder courses, and surface courses. Understand how to handle materials safely, including storage, mixing, and laying temperatures for hot-rolled asphalt.
- →Subgrade Preparation and Compaction: Properly preparing the subgrade (the natural ground) is crucial to prevent future settlement. This involves grading, compacting to the correct density (e.g., using a Proctor test), and ensuring drainage to avoid water damage.
- →Kerbs, Channels, and Edgings: Laying kerbs and channels requires accurate alignment, levels, and jointing. You must know how to set out using string lines, use concrete haunching for stability, and ensure falls for water runoff.
- →Surface Course Laying and Finishing: Techniques for laying asphalt or concrete include using a paver, screeding, and compacting with rollers. Achieving the correct surface texture and camber (crossfall) is essential for skid resistance and drainage.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate interpretation of method statements, risk assessments, and work schedules related to high friction surfacing operations.
- Award credit for evidence of organizing the sequence of operations with team members, including clear communication and coordination of plant movement.
- Award credit for compliance with legislation such as the Health and Safety at Work Act, COSHH, and road traffic regulations, shown through safe operating procedures and use of PPE.
Assessment Guidance
Guidance for achieving higher grades
- 💡When completing portfolio evidence, include annotated photographs of machine checks, test strips, and final surface texture to demonstrate quality control.
- 💡Ensure witness testimonies specifically reference your ability to work to time constraints and minimize disruption to traffic flow, as time management is a key assessment criterion.
- 💡When answering questions about laying kerbs, always mention the importance of using a string line for alignment and a spirit level for crossfall. Examiners look for practical details like 'haunching concrete should be mixed to a 1:3:6 ratio (cement:sand:aggregate) and compacted to avoid voids.'
- 💡For health and safety questions, don't just list PPE – explain why each item is needed. For example, 'High-visibility clothing ensures you are seen by plant operators and traffic, reducing the risk of collision.' Also, reference specific regulations like the Construction (Design and Management) Regulations 2015.
- 💡In practical assessments, demonstrate correct manual handling techniques: keep your back straight, lift with your legs, and avoid twisting. Examiners will observe your technique and note if you use mechanical aids like wheelbarrows or lifting equipment for heavy kerbs.
Common Mistakes
Common errors to avoid in your coursework
- Misinterpreting the specified application rate or treatment depth for high friction surfacing, leading to inadequate skid resistance or material wastage.
- Failing to check the compatibility of equipment (e.g., spray bars, screeds) with the surfacing material, causing blockages or uneven application.
- Misconception: 'Any type of asphalt can be used for any road layer.' Correction: Different layers require specific asphalt types. For example, a base course uses a coarser aggregate (e.g., DBM – Dense Bitumen Macadam) for strength, while the surface course uses a finer mix (e.g., HRA – Hot Rolled Asphalt) for durability and skid resistance.
- Misconception: 'Compaction is only about rolling the surface.' Correction: Compaction must be achieved in layers (lifts) of the correct thickness, typically 50-100mm for asphalt. Under-compaction leads to rutting, while over-compaction can cause cracking. Use a nuclear density gauge or core samples to verify.
- Misconception: 'Health and safety paperwork is just bureaucracy.' Correction: Risk assessments and method statements are live documents that prevent accidents. For example, a RAMS for working near traffic must include traffic management plans, exclusion zones, and emergency procedures – ignoring them can lead to serious injuries or fatalities.
