A Guide to Asbestos Containing Materials (ACMs) in UK Highway Infrastructure

Asbestos remains one of the most significant legacy risks within transportation infrastructure across the United Kingdom. Although the use of asbestos was banned decades ago, many older highway assets still contain Asbestos Containing Materials (ACMs) that require careful identification, monitoring, and management.

As the UK continues modernising transport infrastructure, authorities are increasingly combining traditional asbestos management practices with technologies such as AI infrastructure inspection UK, digital road inspection technology, and AI asset condition monitoring UK to improve safety, compliance, and long-term asset management.

This guide explains the purpose of the General Asbestos Management Plan (GAMP), the types of ACMs commonly found in highway infrastructure, and the strategies used to safely manage asbestos across the UK road network.

Why Asbestos Remains a Critical Infrastructure Challenge

Asbestos was widely used throughout the twentieth century because of its:

  • Fire resistance
  • Durability
  • Thermal insulation properties
  • Cost-effectiveness

However, when asbestos-containing materials are damaged or disturbed, microscopic fibres can become airborne. Exposure to these fibres can cause serious health conditions, including:

  • Mesothelioma
  • Lung cancer
  • Asbestosis
  • Pleural disease

Because of these risks, the UK's Control of Asbestos Regulations (CAR) require strict management procedures for public infrastructure assets, including highways, bridges, tunnels, and associated facilities.

Understanding the General Asbestos Management Plan (GAMP)

The General Asbestos Management Plan (GAMP) provides the framework used across the Strategic Road Network (SRN) to identify, manage, and control asbestos-related risks.

The plan supports compliance with Regulation 4 of the Control of Asbestos Regulations, which establishes the legal duty to manage asbestos within non-domestic premises and infrastructure assets.

Core Objectives of GAMP

The GAMP framework focuses on:

  • Identifying ACMs within highway infrastructure
  • Recording asbestos locations and conditions
  • Monitoring deterioration and potential exposure risks
  • Supporting compliance and reporting requirements
  • Providing workforce training and awareness
  • Establishing safe maintenance and inspection procedures

Modern asset owners increasingly supplement these activities using AI infrastructure risk assessment systems and AI road compliance monitoring UK solutions that improve visibility across large infrastructure portfolios.

Common Locations of ACMs in UK Highway Infrastructure

Much of the UK's strategic road network was constructed before the asbestos ban, meaning ACMs may still exist in various highway assets.

Bridges and Structural Assets

Common ACM locations include:

  • Permanent formwork
  • Bearing assemblies
  • Expansion joint filler boards
  • Gaskets and sealing materials

These components often require specialist assessment during bridge inspections and refurbishment projects.

Drainage Systems

Asbestos-containing materials may also be present in:

  • Drainage pipes
  • Culverts
  • Protective insulation materials
  • Bituminous coatings

Effective monitoring helps prevent accidental disturbance during maintenance works.

Electrical Infrastructure

Older highway electrical systems may contain ACMs within:

  • Control cabinets
  • Fuse boards
  • Switchgear panels
  • Lighting column assemblies

Many highway authorities now use digital road asset surveys UK to maintain accurate inventories of aging infrastructure components.

Tunnels and Underground Assets

Tunnel environments frequently contain asbestos in:

  • Ventilation systems
  • Fireproofing materials
  • Cable duct insulation
  • Roof and wall cladding systems
  • Rope gaskets

These confined environments require particularly stringent management procedures.

Highway Maintenance Activities That May Encounter ACMs

Several routine and major highway operations may involve asbestos-related risks.

Major Infrastructure Projects

Projects involving:

  • Road widening
  • Junction improvements
  • Bridge rehabilitation
  • Tunnel upgrades

often require detailed asbestos surveys before construction begins.

Routine Maintenance

Daily operational activities can also disturb ACMs, including:

  • Sign replacement
  • Drainage maintenance
  • Lighting upgrades
  • Vegetation management
  • Pavement repairs

Using Road hazard monitoring AI systems helps agencies better identify potential infrastructure risks before maintenance crews are deployed.

Emergency Response Activities

Emergency situations may require rapid interventions, including:

  • Vehicle collisions
  • Fire damage
  • Storm-related repairs
  • Surface failures

These incidents demand immediate asbestos risk assessments before repair works commence.

Compliance Framework for Managing ACMs

The GAMP establishes a structured compliance process involving:

Area Asbestos Management Plans (AAMPs)

These plans manage asbestos risks across specific geographic regions.

Scheme Asbestos Management Plans (SAMPs)

Project-specific plans are developed for construction, maintenance, and improvement schemes.

Audits and Monitoring

Regular audits verify:

  • Compliance with asbestos regulations
  • Safe working procedures
  • Record accuracy
  • Risk management effectiveness

Many organisations now integrate AI smart infrastructure management platforms to streamline compliance monitoring and asset reporting across extensive road networks.

The Growing Role of Technology in Asbestos Asset Management

Managing asbestos across thousands of kilometres of highways presents significant logistical challenges.

Modern infrastructure operators increasingly rely on:

These technologies help agencies:

  • Identify deteriorating infrastructure faster
  • Prioritise inspections
  • Improve workforce safety
  • Maintain accurate asset records
  • Support regulatory compliance

The result is a more proactive and data-driven approach to asbestos management.

Training and Workforce Competency

Effective asbestos management depends heavily on workforce awareness and competency.

Personnel involved in:

  • Highway maintenance
  • Bridge inspections
  • Construction activities
  • Asset management

must receive appropriate asbestos awareness training.

Training programs focus on:

  • Recognising ACMs
  • Understanding risk levels
  • Following safe work procedures
  • Emergency response protocols
  • Documentation requirements

This ensures that asbestos risks are consistently managed across all operational activities.

Monitoring, Reviews, and Continuous Improvement

The GAMP framework is reviewed regularly to ensure ongoing effectiveness.

Annual reviews evaluate:

  • ACM condition trends
  • Compliance performance
  • Incident reports
  • Audit findings
  • Emerging risks

Combined with digital road asset surveys UK and modern asset intelligence platforms, these reviews support continuous improvement in infrastructure safety management.
