Full title and description

STB PD 6682-5-2005 (2011) — national adoption (STB) of Published Document PD 6682-5:2005, "Aggregates — Lightweight aggregates for bituminous mixtures and surface treatments and for unbound and bound applications. Guidance on the use of BS EN 13055-2." The document provides practical guidance for applying the European standard BS EN 13055-2 in national/regional work, with particulars on material classification, properties and recommended uses for lightweight aggregates in road and surface treatments.

Abstract

This Published Document explains the intent and application of BS EN 13055-2 for lightweight aggregates (mineral-origin LWA and LWA fillers) when used in bituminous mixtures, surface treatments and in unbound or hydraulically bound layers (excluding concrete, mortar and grout). It summarises requirements, typical tests and regulatory context to help specifiers, producers and testing laboratories apply the EN requirements consistently.

Scope

PD 6682-5 gives guidance on the use of BS EN 13055-2. BS EN 13055-2 covers lightweight aggregates (LWA) intended for bituminous mixtures and surface treatments and for use in unbound and hydraulically bound applications other than concrete, mortar and grout. It includes LWA of mineral origin and recycled or by‑product materials with particle densities not exceeding 2 000 kg/m3 or loose bulk densities not exceeding 1 200 kg/m3, and describes how those materials should be classified and assessed for such uses.

Key topics and requirements

• Guidance on applying BS EN 13055-2 to design, specification and testing of lightweight aggregates for road and surface applications.
• Definitions and classification criteria for LWA (particle density and loose bulk density limits).
• Types of acceptable materials: natural LWA, manufactured LWA, industrial by-products and recycled aggregates.
• Recommended tests and conformity checks (referencing relevant EN test methods and links to Construction Products Directive provisions where applicable).
• Practical notes for specifiers and suppliers on selection of material for bituminous mixtures, surface treatments and unbound/hydraulically bound layers.

Typical use and users

Used by highway and pavement engineers, materials laboratories, aggregate producers and suppliers, road contractors, specification authors and national/regional standards or regulatory bodies. Typical applications include specification and acceptance of lightweight aggregates for asphalt mixtures, surface dressing, base and sub-base layers where lower density or specific mechanical/thermal properties are required.

Related standards

Primary normative reference is BS EN 13055-2 (Lightweight aggregates — part 2). Related documents and tests include other PD 6682 parts (guidance on the EN series for aggregates), BS EN 13055-1, BS EN 13108 (bituminous mixtures), BS EN 13242 (aggregates for unbound and hydraulically bound materials), and a number of EN test standards for particle size, density and mechanical properties.

FAQ

Q: What is this standard?

A: STB PD 6682-5-2005 (2011) is the national designation/adoption of the Published Document PD 6682-5:2005 — guidance on using BS EN 13055-2 for lightweight aggregates in bituminous, unbound and bound applications (excluding concrete, mortar and grout). It is a guidance (PD) document rather than a formal national technical specification replacing the EN.

Q: What does it cover?

A: It explains the scope and application of BS EN 13055-2, sets out classification criteria (including particle and bulk density limits), lists typical tests and gives practical selection and specification guidance for lightweight aggregates used in road construction and surface treatments.

Q: Who typically uses it?

A: Road and pavement engineers, aggregate producers and suppliers, testing laboratories, contracting organisations and standards or regulatory authorities responsible for materials specification and acceptance in transport and civil engineering works.

Q: Is it current or superseded?

A: The Published Document PD 6682-5:2005 is recorded as current/active in BSI records and was reviewed/confirmed in December 2011; the STB adoption is dated 2011. Users should always check national/regional catalogues for any later revisions or harmonised updates in their jurisdiction.

Q: Is it part of a series?

A: Yes — PD 6682 is a multi‑part Published Document series providing guidance on the use of the suite of EN standards for aggregates (parts cover aggregates for concrete, bituminous mixtures, mortar, lightweight aggregates for concrete, lightweight aggregates for bituminous uses, unbound materials, armourstone, and guidance on EN test methods). PD 6682-5 is the part addressing BS EN 13055-2.

Q: What are the key keywords?

A: Lightweight aggregates (LWA), BS EN 13055-2, PD 6682-5, aggregates guidance, bituminous mixtures, surface treatments, unbound layers, STB adoption.
