Geotechnical investigation and testing - Geotechnical monitoring by field instrumentation - Part 5: Stress change measurements by total pressure cells (TPC) (ISO 18674-5:2019)
This document specifies the measurement of stress changes by means of total pressure cells (TPC). General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674‑1. If applied in conjunction with ISO 18674‑4, this document allows the determination of effective stress acting in the ground. This document is applicable to: — monitoring changes of the state of stress in the ground and in geo-engineered structures (e.g. in earth fill dams or tunnel lining); — monitoring contact pressures at the interface between two media (e.g. earth pressure on retaining wall; contact pressure at the base of a foundation); — checking geotechnical designs and adjustment of construction in connection with the Observational Design procedure; — evaluating stability during or after construction. Guidelines for the application of TPC in geotechnical engineering are presented in Annex B. NOTE This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of total pressure cells as part of the geotechnical investigation and testing according to EN 1997-1[1] and EN 1997-2[2].

Road marking materials - Preformed road markings
This European Standard specifies construction products which are white and yellow, removable or non-removable, preformed road marking materials, under the form of tape, cold plastic, thermoplastics with or without drop-on materials, to be used for permanent and/or temporary road markings in circulation areas. Other products and colours intended for road markings are not covered in this European Standard. This European Standard also gives specifications for the evaluation of conformity for white and yellow, removable or non-removable, preformed road materials under the form of tape, cold plastic, thermoplastics with or without drop-on materials to be used for permanent and/or temporary road markings in circulation areas including type testing and factory production control. This European Standard includes an Annex ZA for tapes, preformed cold plastic road marking and thermoplastic road marking with and without drop-on materials with the clauses addressing the provisions of the EU Construction Product Directive for permanent road marking.

Bituminous mixtures - Test methods - Part 48: Interlayer Bonding
This European Standard specifies test methods for determining the bond strength between an asphalt layer and other newly constructed construction layers or existing substrates in road or airfield pavements. The tests can also be applied on laboratory prepared interlayers. Further informative test methods are defined for evaluating the complex bond stiffness between road construction layers. The normative tests described in this standard are - Torque Bond Test (TBT), generally applicable to any layer thicknesses - Shear Bond Test (SBT), generally applicable to layer thicknesses ≥ 15 mm - Tensile Adhesion Test (TAT), generally applicable to layer thicknesses < 15 mm NOTE 1: Further non normative test methods are described in informative annexes: - Annex A (informative) - Compressed shear bond test (CSBT) - Annex B (informative) - Cyclic compressed shear bond test (CCSBT) - Annex C (informative) - Alternative Shear bond test (ASBT) - Annex D (informative) - Layer Adhesion Measuring Instrument (LAMI)
