Asphalt Laying Safety

Asphalt laying involves spreading, levelling, and compacting hot bituminous material to create road and pavement surfaces.
Hot mix asphalt is delivered to site at temperatures between 140°C and 180°C — contact causes instant, severe burns.
Bitumen fumes from hot asphalt are classified as a potential carcinogen — exposure must be minimised at all times.
The paving machine operator must have clear visibility and communication with the laying gang walking behind the paver.
Roller operators compact the asphalt immediately behind the laying gang — physical separation between gang and roller is critical.
Manual raking and levelling of hot asphalt exposes workers to heat, fumes, and sustained physically demanding postures.
Joints between new and existing surfaces must be properly cut and sealed — working near live traffic adds additional risk.
Night laying operations are common to minimise traffic disruption, introducing fatigue and reduced visibility hazards.
Pre-coated chippings, tack coat, and bond coat materials require specific handling procedures and PPE.
Coordination between the paver, rollers, material delivery wagons, and the laying gang is essential for safe operation.

Severe burns	Asphalt at 160°C causes instant full-thickness burns — thermal gloves and waterproof clothing are the minimum protection.
Fume exposure	Bitumen fumes are a potential carcinogen — workers must position upwind and minimise inhalation exposure at all times.
Roller crush	Compaction rollers operate directly behind the laying gang — clear separation and communication prevent fatal crush injuries.

Do

Don't

Wear thermal-resistant gloves and waterproof boots when working with hot asphalt.
Position yourself upwind of hot asphalt to minimise fume inhalation during laying.
Maintain clear separation between the laying gang and compaction rollers at all times.
Use the paver's communication system to coordinate with the operator during laying.
Manage fatigue during night laying operations with proper rest breaks and rotation.
Wear RPE when fume exposure cannot be controlled by positioning alone.
Use traffic management when laying adjacent to live carriageways or public footpaths.
Handle tack coat and bond coat materials with the PPE specified in the COSHH assessment.
Drink water regularly to stay hydrated when working near hot asphalt in warm weather.
Brief the team on the laying sequence, roller positions, and communication signals daily.

DON'T handle hot asphalt without thermal gloves and waterproof protective clothing.
DON'T stand downwind of hot asphalt — bitumen fumes are a potential carcinogen.
DON'T allow rollers to operate without clear separation from the laying gang.
DON'T work behind the paver without communication with the operator established.
DON'T work excessive hours during night laying without following fatigue management rules.
DON'T breathe in bitumen fumes — use RPE when wind conditions prevent upwind positioning.
DON'T lay asphalt near live traffic without approved traffic management fully installed.
DON'T handle coating materials without the PPE specified for the specific product.
DON'T ignore dehydration — hot asphalt work combined with warm weather causes heat illness.
DON'T skip the daily briefing — roller positions and communication arrangements must be confirmed.
