Railway applications - Infrastructure - Hollow sleepers and bearers
Scope: This document defines technical criteria and control procedures which are satisfied by hollow sleepers and bearers used in ballasted track with Vignole rails. The hollow sleepers and bearers designed for ballasted track can also be used in ballastless track. In this case, the requirements are defined by the customer.

Road materials - Environmental product declarations - Product category rules complementary to EN 15804 for bituminous mixtures
Scope: This document provides a common European basis with Complementary Product Category Rules (c-PCR) to EN 15804 for the preparation of Environmental Product Declarations for bituminous mixtures used on roads, airfields and other trafficked areas covered by relevant product standards in the EN 13108-series.
Complementary to EN 15804, this document:
— specifies the declared unit;
— defines the system boundaries for bituminous mixtures;
— specifies and describes the default scenarios and rules for defining scenarios for certain life cycle information modules.
This document applies to the preparation of EPD for the following module configurations:
— cradle to gate with modules C1-C4 and module D. This includes the declaration of the minimum modules: A1-A3 (product stage), C1-C4 (end-of-life stage) and D (supplementary information beyond the pavement life cycle);
— cradle to gate with options, modules C1-C4 and module D, only when the added optional modules are A4 and/or A5. This includes the declaration of the minimum modules (as above), plus A4 (transport) and/or A5 (construction – installation process).
This document does not cover modules B1-B7.

Eurocode 7 - Geotechnical design - Part 1: General rules
Scope: 1.1 Scope of EN 1997 1
(1) This document provides general rules for the design and verification of geotechnical structures.
(2) This document is applicable for the design and verification of geotechnical structures outside the scope of EN 1997 3.
NOTE In this case, additional or amended provisions can be necessary.
1.2 Assumptions
(1) In addition to the assumptions given in EN 1990, the provisions of EN 1997 (all parts) assume that:
— ground investigations are planned by individuals or organisations with knowledge of potential ground and groundwater conditions;
— ground investigations are executed by individuals with appropriate skills and experience;
— the evaluation of test results and derivation of ground properties from the ground investigation are carried out by individuals with appropriate geotechnical experience and qualifications;
— the data required for design are collected, recorded, and interpreted by appropriately qualified and experienced individuals;
— geotechnical structures are designed and verified by individuals with appropriate qualifications and experience in geotechnical design;
— adequate continuity and communication exist between the individuals involved in data collection, design, verification and execution.
(2) This document is intended to be used in conjunction with EN 1990, which establishes principles and requirements for the safety, serviceability, robustness, and durability of structures, including geotechnical structures, and other construction works.
NOTE Additional or amended provisions can be necessary for assessment of existing structures, see EN 1990 2.
(3) This document is intended to be used in conjunction with EN 1997 2, which gives provisions for determining ground properties from ground investigations.
(4) This document is intended to be used in conjunction with EN 1997 3, which gives specific rules for the design and verification of certain types of geotechnical structures.
(5) This document is intended to be used in conjunction with other Eurocodes for the design of geotechnical structures, including temporary geotechnical structures.

Bituminous mixtures - Test methods - Part 12: Determination of the water sensitivity of bituminous specimens
Scope: This document specifies three test methods for determining the effect of saturation and accelerated water conditioning:
- method A uses the indirect tensile strength of cylindrical specimens of bituminous mixtures;
- method B uses the compression strength of cylindrical specimens of bituminous mixtures;
- method C defines the bonding value for a bituminous mixture 1 h after mixing, where the bonding of bitumen and aggregate can be equated to a bonding value.
Method C is suitable for soft asphalt with bitumen of kinematic viscosity at 60 °C of 4 000 mm2/s or less.
These methods can be used to evaluate the effect of water on asphalt mixtures with or without anti-stripping additives including liquids, such as amines; and fillers, such as hydrated lime or cement.
