GOST 32729-2014 PDF

Full title and description

ГОСТ 32729-2014 — «Дороги автомобильные общего пользования. Метод измерения упругого прогиба нежестких дорожных одежд для определения прочности». English: "Automobile roads of general use — Method of measuring elastic deflection to determine the strength of non‑rigid pavement."

Abstract

Standard specifies a method for measuring elastic deflection (progib) of non‑rigid pavement structures under dynamic and/or static loading to assess their bearing capacity (strength). Results are intended for use in diagnostics, evaluation of pavement condition and in design or rehabilitation decision‑making. The method covers measurement procedures, required equipment characteristics (including falling‑weight and similar deflection devices), measurement points and basic interpretation of results.

General information

• Status: Active (introduced into application in the Russian Federation as a national standard).

• Publisher: Стандартинформ (Moscow) — official publication of the interstate standard text.
• ICS / categories: Civil engineering — Road works; classification 93.080.01 (road construction / testing).
• Edition / version: First edition, 2014 (ГОСТ 32729-2014).
• Number of pages: Short national publication — bibliographic entry lists II, 5 pages (concise standard text).

Scope

Applies to measurement of elastic deflection of non‑rigid (flexible) pavement structures on public automobile roads. The method covers dynamic and static loading tests used to determine pavement strength and to derive parameters (deflection basin, equivalent modulus) for diagnosis and further engineering evaluation. It is intended for use by road authorities, testing laboratories and organizations performing pavement condition assessment.

Key topics and requirements

• Definitions and terminology for elastic deflection (progib) of non‑rigid pavements.
• Measurement procedures for dynamic (e.g., falling‑weight deflectometer, FWD) and applicable static loading tests, including test sequence and positioning of sensors.
• Equipment characteristics, calibration and verification requirements to ensure measurement accuracy.
• Sampling, spacing of test points and requirements for number of measurements to characterise pavement sections.
• Data processing: determination of deflection basins, calculation of equivalent moduli or indicators of bearing capacity, and rules for reporting results.
• Use of results for assessing strength, planning rehabilitation and supporting design or maintenance decisions.

Typical use and users

Used by road authorities, pavement engineering laboratories, design and research institutes, contractors performing acceptance and diagnostic testing, and consultants involved in pavement evaluation and rehabilitation planning. Typical applications include network‑level diagnostics, local investigation before repair or reconstruction, and verification of construction quality.

Related standards

Q: What does it cover?

A: Procedures for conducting dynamic and applicable static deflection tests (including use of devices such as falling‑weight deflectometers), equipment requirements, measurement layouts, data processing and use of results to assess pavement strength.

Q: Who typically uses it?
