Bituminous mixtures - Test method - Part 33: Specimen prepared by roller compactor
This document specifies the methods for compacting parallelepipedal specimens (slabs) of bituminous mixtures, to be used directly for subsequent testing, or from which test specimens are cut. For a given mass of bituminous mixture, the specimens are prepared either under controlled compaction energy, or until a specified volume and therefore air voids content is obtained. This document describes the following methods of compaction: - method using a wheel or two wheels fitted with pneumatic tyres; - methods using a steel roller, which includes 3 different procedures: - steel roller; - steel roller used on wheel fitted with pneumatic tyres; - steel roller running on vertical sliding steel plates; - method using a steel roller sector. This document is applicable to bituminous mixtures manufactured in the laboratory or in a mixing plant.

Bituminous mixtures - Test methods - Part 44: Crack propagation by semi-circular bending test
This document specifies the Semi-Circular Bending (SCB) test method to determine the tensile strength or fracture toughness of an asphalt mixture for the assessment of the potential for crack propagation. The results of the test can be used to calculate: - the maximum load that the material containing a notch (crack) can resist before failure; - when the presence of a notch is critical. It should be noted that the test only describes a method to determine the resistance to crack propagation of an asphalt mixture. The crack propagation phase describes the second part of failure mechanism during dynamic loading. The first phase, which is the crack initiation phase, is mainly covered by the fatigue test (EN 12697-24).

Bituminous mixtures - Test methods - Part 32: Specimen preparation by vibratory compactor
This document specifies a method for the preparation of bituminous test specimens using a vibratory compaction technique. This document is applicable to loose mixtures and cores and is used to establish a refusal density for a bituminous mixture, or to determine the ease of compaction as described in EN 12697-10.

Geotechnical investigation and testing - Laboratory testing of soil - Part 11: Permeability tests (ISO 17892-11:2019)
This International Standard specifies methods for the laboratory determination of the water flow characteristics in soil. This International Standard is applicable to the laboratory determination of the coefficient of permeability of soil within the scope of geotechnical investigations. The permeability test is carried out on a cylindrical test specimen that is either confined laterally by a rigid container or by a flexible membrane. The specimen is subjected to differential hydraulic head and the water flow is measured under either a constant or falling head. The results are used to determine the coefficient of permeability of the soil specimen. Tests may be carried out on undisturbed, remoulded, compacted or reconstituted specimens. The calculation of coefficient of permeability assumes the application of Darcy’s law for laminar flow under saturated conditions. The size of the specimen may not adequately represent the fabric features present in field conditions.

Bituminous mixtures - Test methods for hot mix asphalt - Part 32: Laboratory compaction of bituminous mixtures by vibratory compactor CONSOLIDATED TEXT
This European Standard describes a test method for the preparation of bituminous test specimens using a vibratory compaction technique. This European Standard is applicable to loose mixtures and cores and is used to establish a reference density for a bituminous mixture in accordance with the procedures described in EN 12697-9, or the ease of compaction as described in EN 12697-10.

Geotechnical investigation and testing - Laboratory testing of soil - Part 11: Determination of permeability by constant and falling head
This document is intended for use in earthworks and foundation engineering. It specifies laboratory test methods to establish the coefficient of permeability of water through water-saturated soils. In the proposed laboratory tests soil specimens are subjected to a flow of water passing through the specimen. The water pressure conditions and volume of water passing through the specimens are measured for evaluation of the permeability. The results obtained serve to calculate groundwater flow and to assess the permeability of man-made impervious layers and filter layers.
