Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: laying and compaction of final asphalt wearing course on site. It ensures the work is planned in advance, the correct resources and controls are in place, and all personnel understand responsibilities, sequence, quality requirements, and safety controls before work begins. It aligns site execution with the documented scope and acceptance expectations.
Who uses this method statement
This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.
When it is prepared and submitted
The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.
Who reviews or approves it
The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.
Important approval note
This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.
For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.
Method statement content
Scope
Overview
This method statement covers the supply, laying, and compaction of the final asphalt wearing course, including temperature-controlled delivery and placement, non-tracking tack application and truck management, precise paver operation with automatic grade/slope control, seamless longitudinal and transverse joints, steel-wheel and pneumatic-tyre rolling sequences, and post-construction verification of surface texture and riding quality using straightedge, texture tests, and inertial profilometer.
Extents
- Final wearing course for carriageways, ramps, shoulders, and tie-ins.
- Integration with existing asphalt at interfaces and structures (manholes, gullies, bridge joints) [Verify per drawings].
Exclusions
- Base and binder course construction (covered under separate methods).
- Major geometric corrections (>20 mm) prior to wearing course (to be completed before this activity).
Key Objectives
- Achieve target layer thickness and density with uniform texture.
- Construct tight, durable, low-permeability joints.
- Meet smoothness (IRI) and straightedge tolerances.
- Maintain strict thermal regime to avoid segregation, tenderness, flushing, or premature cooling.
