AS NZS 1141.8-2014 PDF

Full title and description

AS/NZS 1141.8:2014 — Methods for sampling and testing aggregates, Method 8: Water‑soluble fraction of filler. This joint Australian/New Zealand standard specifies a laboratory procedure for determining the water‑soluble fraction present in mineral filler intended for use in asphalt and other bituminous mixtures; the result is used in quality control and acceptance of filler materials for pavement surfacing applications.

Abstract

AS/NZS 1141.8:2014 provides a short, prescriptive test method to extract and quantify the proportion of material in filler that is water‑soluble. The procedure supports assessment of filler quality (impurities, soluble salts or fines) which can affect asphalt durability, binder interaction and long‑term pavement performance. The part is one element of the AS/NZS 1141 series covering sampling and laboratory tests for aggregates.

Scope

This part of AS/NZS 1141 specifies the procedure for determining the water‑soluble fraction of mineral filler used in asphalt. It applies to laboratory samples of filler and is intended for use in material acceptance, routine quality control testing and specification compliance for asphalt production. It is narrowly focused on the water‑soluble component and does not replace other physical or chemical tests in the AS/NZS 1141 series.

Key topics and requirements

• Definition of test sample and preparation rules for filler material.
• Procedure for extraction of water‑soluble constituents and determination of the soluble fraction (quantitative measurement expressed as percentage by mass).
• Requirements for laboratory apparatus, reagents, and reporting of results (including repeatability/precision expectations for routine QC).
• Intended use of results for acceptance criteria, specification conformance and assessment of potential deleterious materials in filler for asphalt mixes.

Typical use and users

Primary users are materials testing laboratories (NATA/IANZ accredited labs in Australia/New Zealand), quarry and asphalt plant quality managers, pavement designers, road authorities and contractors responsible for production and acceptance of asphalt. Typical use cases include incoming filler acceptance, periodic quality surveillance, contract compliance testing and investigations where chloride/salt or other soluble fines are suspected to affect mix performance.

Related standards

AS/NZS 1141.8:2014 is one part of the AS/NZS 1141 series (Methods for sampling and testing aggregates). Commonly referenced related parts include test methods for particle size distribution (AS 1141.11 series), materials finer than 75 μm (AS 1141.12), voids in dry compacted filler (AS/NZS 1141.17) and many other AS 1141 methods used together for aggregate and asphalt testing. It is also used in conjunction with asphalt sampling/testing standards (AS/NZS 2891 series) and pavement material specifications.

FAQ

Q: What is this standard?

A: AS/NZS 1141.8:2014 is the joint Australian/New Zealand standard that specifies the laboratory method for determining the water‑soluble fraction present in mineral filler used in asphalt mixtures.

Q: What does it cover?

A: It covers sampling requirements for the test sample and a step‑by‑step laboratory extraction and measurement procedure to quantify the water‑soluble portion of filler material, used for material acceptance and quality control. It does not cover unrelated physical tests (e.g., particle shape, Los Angeles abrasion) which are found in other AS/NZS 1141 parts.

Q: Who typically uses it?

A: Accredited materials testing labs, quarry and asphalt plant QC staff, road agencies, engineers and contractors involved in asphalt production and pavement specification compliance.

Q: Is it current or superseded?

A: The 2014 publication is listed and sold as the current AS/NZS 1141.8 edition (first edition, 2014). Users should confirm currency before relying on it for contractual purposes by checking the issuing bodies or their procurement channels.

Q: Is it part of a series?

A: Yes — it is Part 8 of the AS/NZS 1141 series (Methods for sampling and testing aggregates). The series contains many related parts covering particle size, density, strength, shape, durability and other aggregate properties used in concrete, asphalt and pavement engineering.

Q: What are the key keywords?

A: Water‑soluble fraction, filler, mineral filler, aggregates testing, AS/NZS 1141, asphalt, quality control, sampling, Standards Australia, Standards New Zealand.
