GOST 33140-2014 PDF

Full title and description

GOST 33140-2014 — Automobile roads of general use. Viscous road petroleum bitumens. Method for determining aging under high temperature and air (RTFOT). The standard specifies a short-term ageing procedure (Rolling Thin-Film Oven Test) for viscous petroleum road bitumens used as binders in construction, reconstruction and repair of road pavements.

Abstract

This standard defines the RTFOT (rolling thin‑film oven) method for simulating short‑term thermal and oxidative ageing of viscous road petroleum bitumens. It covers sample preparation, oven and specimen handling, test parameters and determination of changes in mass and binder properties after exposure to high temperature and air. The method is intended to provide reproducible conditioned material for subsequent property measurements.

Scope

The standard applies to viscous petroleum road bitumens intended for use as binders in road pavements and specifies the procedure to determine short‑term ageing under the combined action of elevated temperature and air using the RTFOT apparatus. It is used to produce aged binder samples for comparison of selected properties before and after the ageing treatment.

Key topics and requirements

• Definition and purpose of the RTFOT short‑term ageing method for viscous road bitumens.
• Sample preparation requirements (drying/dehydration, heating to a flowable state, filtration and homogenization prior to testing).
• Specified specimen mass and containment (example: glass bottles loaded with nominal sample mass, commonly 35 g per bottle for the RTFOT procedure).
• Test conditions and apparatus operation: rotating drum speed (≈15 min−1 / rpm), controlled airflow to each specimen (≈4.0 l/min), oven temperature and specified test duration (the standard prescribes precise temperatures and an ageing time around the RTFOT range).
• Determination and reporting of changes caused by ageing — commonly mass loss (percentage change), and subsequent measurement of binder properties (e.g., penetration, softening point, viscosity or other specified characteristics) on the aged material.
• Requirements for laboratory conditions, equipment verification and test repeatability; instructions for evaluating invalid tests and repeating where precondition limits are not met.

Typical use and users

Used by testing laboratories, road‑construction engineers, bitumen producers and quality control departments to assess short‑term thermal/oxidative ageing susceptibility of binders. The method is applied in material specification, quality control during production and acceptance testing for pavement projects.

Related standards

GOST 33140-2014 is part of the road‑construction and bitumen testing family of standards. It cross‑references national sampling and test procedures (for example, sampling standards such as GOST 2517 are cited for sample collection) and is broadly equivalent in purpose to international RTFOT methods (EN 12607‑1, ASTM D2872 / AASHTO T240) used to simulate short‑term binder ageing. Users commonly apply it alongside GOST methods for penetration, softening point and viscosity determinations.

FAQ

Q: What is this standard?

A: It is a GOST (interstate) standard that specifies the rolling thin‑film oven test (RTFOT) procedure to determine short‑term thermal and oxidative ageing of viscous petroleum road bitumens.

Q: What does it cover?

A: It covers sample preparation, apparatus and operating conditions, test sequence, and how to determine and report changes in binder mass and properties after RTFOT conditioning.

Q: Who typically uses it?

A: Accredited testing laboratories, bitumen manufacturers, road authorities and contractors for quality control, specification compliance and comparative evaluation of binder short‑term ageing.

Q: Is it current or superseded?

A: As published it is shown as an active standard (GOST 33140‑2014) with a recorded amendment in 2020; users should check national catalogues or official distributors for the very latest status and any subsequent amendments.

Q: Is it part of a series?

A: Yes — it belongs to the set of standards for "Automobile roads of general use" and is used together with other GOST test methods for bitumen properties and sampling standards. It is conceptually aligned with international RTFOT standards (EN/ASTM) for short‑term ageing.
