Method Statement: Stone Mastic Asphalt (SMA) Pavement Installation inspection and test plan example.

Inspection and Test Plan for Method Statement: Stone Mastic Asphalt (SMA) Pavement Installation

AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.

Published 08 Aug 2026 Rev. 00 1 views
About this ITP: This ITP defines hold and witness points and acceptance criteria for SMA paving, including high-temperature logistics, fiber dosage control, drain-down, density, and surface finish.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To ensure SMA works comply with the JMF and specifications, safeguarding durability, texture, and safety performance.

Who uses this inspection and test plan

Site engineers, QC technicians, paving supervisors, and the Engineer’s representative.

When this ITP is prepared and submitted

Before and during SMA production paving through to opening to traffic.

Who receives or approves this ITP

Engineer/Client Representative

Inspection scope

Substrate readiness, bond coat, plant production parameters, transport temperatures, compaction process, density, thickness, joints, surface texture and evenness.

Typical hold, witness, and review points

HP1 Pre-paving substrate; WP1 Truck arrival/temperature; Drain-down at start of shift; HP2 Opening to traffic.

Typical inspection records

Batch tickets, temperature logs, drain-down reports, density/thickness logs, joint QA logs, straightedge and texture results, calibration certificates.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Pre-paving substrate inspection (HP1) Cleanliness, dryness, level; surface temp ≥10–15°C [Verify] Substrate compliant; Engineer releases paving to proceed. Site Engineer / Client Rep HP1 checklist signed-off
Tack coat application and break Residual rate verification Residual 0.3–0.5 L/m² asphalt; 0.4–0.8 L/m² milled/concrete [Verify]; ≥90% coverage; fully broken. Paving Supervisor / QC Spray log; photos
Plant mix temperature and fiber dosing Temp at discharge; fiber feeder calibration check Temp 170–190°C typical [Verify]; fiber dosage within ±10% of target; binder content within JMF tolerance. Plant Manager / QC Batch tickets; calibration certs
Truck arrival temperature and load inspection (WP1) Temp ≥150–170°C [Verify]; no segregation/contamination Within limits; otherwise reject or rework per NCR. QC Engineer Delivery log; WP1 record
Drain-down testing (ASTM D6390) Per ASTM D6390 at start of shift/change Drain-down ≤0.3% by mass [Verify]. Lab/QC Lab report
Mat temperature behind screed At start/end of lots and hourly ≥150–170°C immediately behind screed [Verify]. QC Temperature log
Early breakdown compaction tracking Start rolling at ≥145–155°C [Verify]; pass count as per test strip No flushing/aggregate crushing; stone skeleton stable (no lateral movement). Paving Supervisor / QC Rolling pattern sheet
In-situ density (cores or nuclear) ASTM D2950 or EN 12697-6/ -7 96–98% of target bulk density or 92–96% of Gmm [Verify]. QC Engineer Density report; core logs
Layer thickness checks Random checks per lot Within −5/+10 mm of design [Verify]. Site Engineer/QC Thickness check sheet
Joint quality and density 1 per 300 m (min) [Verify] Joint density within −1% of mainline minimum; straightness offset ≤10 mm; fully bonded. QC Engineer Joint QA log
Surface evenness and texture ASTM E965 for texture; straightedge sweeps Evenness ≤4 mm/3 m (wearing); texture ≥1.0 mm [Verify]. QC Engineer Straightedge/texture reports
Opening to traffic (HP2) Cooling to ≤60°C or as specified; QA/QC complete Engineer authorization to open. Engineer / Contractor HP2 permit

Frequently asked questions

Typically one test per 500 m² with a minimum of three per lot; adjust per project specification.

At the start of each shift, whenever mix temperature or materials change, or when segregation/bleeding is suspected.
