EN 13588:2008 (E) 4 Introduction The cohesion is one of the measures of the performance of a bituminous binder. It is important to use binders which have a sufficient level of cohesion according to the level of traffic to be supported. Cohesion has originally been developed for surface dressing however it can be used for any type of binder (pure, modified or fluxed) which is to be used in different types of road applications. Knowledge of cohesion enables the choice of binder type for given traffic and site conditions. This European Standard describes a method for determining the cohesion of a binder and how to draw the cohesion curve as a function of temperature. SIST EN 13588:2008

This method is applicable for pure bitumen, modified bitumen and fluxed bitumen; in the case of fluxed bitumen, the test can be performed on the binder containing fluxant or on binder from which the solvent has been removed. For bitumen emulsions, the test is carried out on the residual binder obtained after recovery and the method used to recover the binder should be reported.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 58, Bitumen and bituminous binders - Sampling bituminous binders EN 12594, Bitumen and bituminous binders - Preparation of test samples 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 cohesion energy per unit area required to fully detach a cube from the support, with the previously-bonded faces of cube and support remaining fully covered by binder NOTE Where the cube remains attached to the support after elastic displacement, the energy value measured by the test is always less than the true cohesion value, so the test result can be used to establish that the binder has more than a specified minimum value of cohesion. 4 Symbols and abbreviations For the purposes of this European Standard, the following symbols and abbreviations apply. α

The assembly is brought to the test temperature and the cube is dislodged by the impact of a swinging pendulum. The energy absorbed by rupture of the binder is calculated from the angle (α) of swing of the pendulum. The determination is performed over a range of at least six temperatures covering the cohesion peak of the binder (see Figure 1). SIST EN 13588:2008

EN 13588:2008 (E) 8 A 360° dial graduated in 0,5° interval, with zero in the lower balance position of the pendulum. NOTE Some dials are graduated in grades from 0 to 400 grades, with 0,5 grade intervals. 6.1.4 Cubes and cube supports, steel, to the forms and dimensions shown in Figure 3, Figure 4 and Figure 5, serrated on the faces to be coated with binder. The mass of any cube is (9,0
± 0,5) g. The precise details for the serrations are not mandatory and alternative configurations may be used provided they do not result in adhesion failure between binder and cube or support during testing. NOTE A minimum of six test assemblies, consisting of a cube attached by a film of binder to the cube support, are suggested for each temperature, and typically a minimum of three different temperatures are needed to show the relationship between cohesion and temperature. It is therefore useful to have 18 assemblies (i.e. cubes and cube supports). 6.2 Oven, capable of maintaining a set temperature of from 60 ºC up to a temperature equal to 85 °C above the ring and ball softening point of the respective binder under test with an accuracy of 5 ºC 6.3 Thermostatically controlled enclosure(s), incubator air bath(s) or liquid bath(s) capable of maintaining the set temperature within ± 1,0 °C over the range (- 10 °C) to (+ 80 °C). 6.4 Temperature reading device, capable of measuring the temperature of the thermostatically controlled enclosure, readable and calibrated to 0,2 °C or less. 6.5 Other apparatus including a brush, spatula and knife blade. 7 Procedure NOTE Sufficient cube and support assemblies for not less than eight different test temperatures should be prepared. 7.1 Preparation of cubes and supports Ensure that the cubes and supports are clean by washing in a suitable solvent and by checking afterwards. If necessary, use a small brush (6.5) to remove contamination from the serrations. Rinse with water containing ethanol, and dry the cubes and supports in an oven and examine to ensure that they are undamaged. Pre-heat cubes and supports for each temperature in the oven at (60 ± 5) °C for at least 60 min. If the cubes and supports are heated to a higher temperature (see 8.3.2 Note), record the temperature used. If the binder is fluxed, the cube and support can be heated for 30 min. If the binder has a softening point above 60 °C accordingly to EN 1427 [1], the cube support shall be heated to the softening point with an accuracy of 5 °C. 7.2 Preparation of the binder for test 7.2.1 E
