This document specifies the test methods for the laboratory determination of the California bearing ratio and immediate bearing index. The tests are appropriate to that part of the mixture up to a maximum particle size of 22,4 mm. When immersion in water is specified as part of the curing of the specimen, this document also includes the determination of vertical swelling of the specimen before the determination of the California bearing ratio.

This document specifies a test method for the determination of the mixing quality and the tendency of segregation in composition of hot bituminous mixtures. This test method is considered suitable for mix-design purposes and for client information. NOTE This test method is based on hot bituminous mixtures. There is no experience for other types of bituminous mixtures, e.g. asphalt concrete with bituminous emulsions.

This document describes two test methods for determining the thickness of bituminous pavement. The first method describes measurements carried out on one or more cores which have been drilled from the full depth of the slab or road structure (destructive method). The second method electro-magnetic (non-destructive) measurement are used.

This document specifies a number of test methods for the determination of the relationship between the water content and the density of unbound and hydraulically bound mixtures under specified test conditions. The test results provide an estimate of the mixture density that can be achieved and provides a reference parameter for assessing the density of the compacted layer of the mixture. The test results are used as a basis for specifying requirements for hydraulically bound and unbound mixtures. The test result also allows a conclusion to be drawn as to the water content at which a mixture can be satisfactorily compacted in order to achieve a given density.

This document specifies a method for measuring the bulk density of pavement mixtures using a transmission-type gamma radiation test bench. This method applies to cylindrical specimens or blocks, prepared in a laboratory or cut from a pavement, the thickness and the mass absorption coefficient which is a function of the chemical composition are known. The thickness of the specimen body traversed by the radiation shall be between 30 mm and 300 mm. The method cannot be applied to materials containing slags, with variable metal content or chemical composition. NOTE Material containing metal or chemical compositions can affect the absorption of gamma rays.

This document specifies a method for the determination of the relationship between the dry density and water content of a mixture using vibrating hammer compaction. This document applies to mixtures which contain no more than 10 % by mass of the mixture retained on the 40 mm test sieve. This document also describes the procedure for calculating and plotting the curves corresponding to 0, 5 and 10 % air voids.

This document specifies a test method to determine the resistance of bituminous materials to de-icing fluids such as solutions of acetate and formate. The procedure determines the surface tensile strength of a specimen of asphalt which has been stored in de-icing fluid. This document is primarily used as a test on asphalt to be laid on airfields, but it can be used for asphalt to be laid on roads or other paved areas.

This document specifies general requirements for common test equipment, calibration procedures and reagents for the testing of bituminous materials in the EN 12697 series of standards. NOTE 1 This document makes use by reference of the requirements for common equipment and calibration prepared for aggregates. NOTE 2 Bodies providing accreditation of test equipment may need to consider alternative requirements and/or calibration frequencies in order to cover the possibilities of National Health & safety, regulatory and legislative requirements. Advice is also given on recommendations for laboratory management (Annex A), on the accuracy of measurement (Annex B) and on the rounding of values for reported results (Annex C).
