(Main)Unbound and hydraulically bound mixtures - Part 2: Test methods for laboratory reference density and water content - Proctor compaction
General Information
- Abstract
This European Standard specifies test methods for the determination of the relationship between the water content and the dry density of hydraulically bound or unbound mixtures after compaction under specified test conditions using Proctor compaction. It allows an estimate of the mixture density that can be achieved on construction sites and provides a reference parameter for assessing the density of the compacted layer of the mixture.
This European Standard applies only to unbound and hydraulically bound mixtures of aggregates used in road construction and civil engineering work. It is not applicable to soils for earthworks. The results of this test method can be used as a basis for comparing mixtures before use in road construction. The test results also allow a conclusion to be drawn as to the water content at which mixtures can be satisfactorily compacted in order to achieve a given dry density.
This test is suitable for mixtures with different values of upper sieve (D) size up to 63 mm and an oversize up to 25 % by mass.

Overview
EN 13286-2:2010 is a CEN European Standard that defines laboratory Proctor compaction test methods to determine the relationship between water content and dry density for unbound and hydraulically bound mixtures used in road construction and civil engineering. The standard provides a laboratory reference density (Proctor and modified Proctor) that estimates the density achievable on site and serves as a reference parameter for assessing the compaction quality of pavement layers. It applies to aggregates mixtures (upper sieve D up to 63 mm) with an oversize up to 25% by mass and is not applicable to soils for earthworks.
Key Topics and Requirements
- Scope and purpose: Establish the dry density / water content curve to determine optimal compaction moisture and compare mixtures prior to use in road construction.
- Test variants: Six similar Proctor and modified Proctor procedures are specified to suit different maximum particle sizes and sample/mould sizes.
- Proctor vs Modified Proctor:
- Proctor test: specific compaction energy ≈ 0.6 MJ/m³ (standard Proctor).
- Modified Proctor: higher energy ≈ 2.7 MJ/m³ for denser compaction.
- Apparatus essentials:
- Rammers with defined masses and drop heights (examples: Rammer A 2.50 kg, 305 mm drop; Rammer B 4.50 kg, 457 mm; Rammer C 15.00 kg, 600 mm).
- Cylindrical moulds sized to the mixture particle size (mould types A, B, C).
- Balances, sieves (EN 933-x), oven (EN 1097-5) and depth gauges for accurate measurement.
- Sample preparation and limitations:
- Procedures for mixtures passing particular sieve sizes, correction methods for oversize material, and handling of self-draining mixtures are described.
- Test not suitable where >25% of material is retained on the 63 mm sieve.
Applications and Who Uses It
- Pavement engineers and designers: to determine target dry density and optimum moisture for base and sub-base layers.
- Construction contractors and site QA/QC teams: for verifying compaction specifications and predicting achievable field densities.
- Materials laboratories and testing bodies: to compare mix designs, control material quality, and produce reference Proctor curves.
- Specifiers and procurement professionals: for setting contractual density and moisture criteria in roadworks and civil engineering projects.
Practical outcomes include establishing the optimum water content for satisfactory compaction, estimating achievable on-site density, and providing a reproducible basis for mix comparison and specification compliance.
