Introduction
Depending on the local experience and availability of products and materials, different binders are used for
roadbases and sub-bases, capping layers, soil stabilization and soil improvement in Europe. These include
cements conforming to EN 197-1 and EN 197-4, building limes conforming to EN 459-1 and hydraulic road
binders presently defined in existing national standards or technical approvals.
Hydraulic road binders are finished products, produced in a factory and supplied ready for use. They are
differentiated according to their strength development in normal hardening hydraulic road binders specified in
this standard and rapid hardening hydraulic road binders specified in EN 13282-1. The Part 3 of EN 13282
defines the conformity evaluation procedure for hydraulic road binders according to this standard.
Binders obtained through mixing of their constituents on site are not covered by this European Standard.
Cements, masonry cements and building limes are also outside the scope of this European Standard, as they
are defined in specific European Standards.

4 HYDRAULIC ROAD BINDER
4.1 General
A hydraulic binder, when mixed with water, hardens both in the air and under water and remains solid, even
under water.
A hydraulic road binder is a factory produced hydraulic binder, supplied ready for use, having properties
specifically suitable for treatment of materials for bases, sub-bases and capping layers as well as earthworks,
in road, railway, airport and other types of infrastructures.
NOTE 1: Hydraulic road binders are not only used for road construction but this general designation will be used for a
better understanding in this document.
A hydraulic road binder consists of a powder made from a blend of different constituents and statistically
homogeneous in composition. A high degree of uniformity in all properties shall be obtained through
continuous mass production processes.
NOTE 2: Continuous production refers to the process, the definition of the product, its composition and properties but does
not imply a 24 hour production.
Qualified and skilled personnel and the facilities to test, evaluate and adjust product quality are essential for
producing normal hardening hydraulic road binders included in this European Standard.
The manufacturing process and its control shall ensure that the composition of a normal hardening hydraulic
road binder is kept within the limits fixed in this European Standard.
4.2 Normal hardening hydraulic road binder
A normal hardening hydraulic road binder is a hydraulic road binder which conforms to the requirements for
strength at 56 days, fineness, initial setting time, soundness and sulfate content.

oSIST prEN 13282-2:2010
prEN 13282-2:2010 (E)
Crystallised basic oxygen furnace slag (Sb) can be added to the other constituents of the normal hardening
hydraulic road binder during its manufacture.The declared value shall be less than 40 %.

- calcium lime (CL) and natural hydraulic lime (NHL) which conform to EN 459-1. CL limes may be either quick
lime (CL-Q) or hydrated lime (CL-S).
5.2 Minor additional constituents
Minor additional constituents (Mac) can be added in a proportion not exceeding 10 % by mass in total.
Minor additional constituents are specially selected, inorganic natural mineral materials, inorganic mineral
materials derived from the clinker or calcium lime production process, or constituents as specified in 5.1
unless they are included as main constituents which, after appropriate preparation and on account of their
particle size distribution, improve the physical properties of the binder (such as workability or water retention).
They can be inert or have slightly hydraulic, latent hydraulic or pozzolanic properties. However, no
requirements are set for them in this respect.
Minor additional constituents shall be correctly prepared, i.e. selected, homogenized, dried and comminuted
depending on their state of production or delivery.
Minor additional constituents shall not impair the properties of the binder.
5.3 Calcium sulfate (Cs)
Calcium sulfate, gypsum, hemihydrate or anhydrite (natural or artificial) can be added to the other constituents
of the normal hardening hydraulic road binder during its manufacture.
5.4 Additives
Additives, for the purpose of this European Standard, are constituents not covered in 5.1 to 5.3 which are
added to improve the manufacture or the properties of the normal hardening hydraulic road binder.
The total quantity of additives, excluding water, should not exceed 1 % by mass of the binder.
A total content of additives over 1 % by mass is permitted provided that quantity and function of each of them
are stated on the packaging and/or on the delivery note.
Additives shall not impair the properties of the normal hardening hydraulic road binder.
6 CLASSIFICATION
Normal hardening hydraulic road binders are designated by the letter N followed by a number representing the
strength class.
The strength class of a normal hardening hydraulic road binder shall be determined by the compressive
strength at 56 days tested in accordance with EN 196-1.
Four strength classes are defined in this European Standard: N 1, N 2, N 3 and N 4 (see § 7.1).
NOTE : Strength classes are incorporated to enable the manufacturer to control quality and are not related to the
mechanical performance of soils or other materials treated with normal hardening hydraulic road binders.
