Asphalt emulsion is a dispersion of bitumen and water, with a cationic or anionic emulsifying agent. The bitumen content in the emulsion is around 60% and based on the mix stability, the emulsion can be Rapid Setting (RS), Medium Setting (MS), or Slow Setting (SC). Different types of emulsions require different tests; the most common are water content, setting time and residue on sieving.
The breaking value is the amount of filler needed to coagulate a bitumen emulsion.
Standards EN 13075-1
The breaking value ia a dimensionless number corresponding to the amount of reference filler, in grams, needed to coagulate 100 g of bitumen emulsions. The test is performed with a set of items comprising:
The above set correspond to the basic “Equipment for manual procedure” prescribed by the EN 13075-1 standard.
To perform the test in the “Semi-automatic procedure”, the set has to be completed by a Stirrer motor (see accessories, model 81-B0139/D) and by a Adjustable filler feeder (see accessories, model 81-B0139/F).
Used to examine the asphalt emulsions.
Standards ASTM D244 AASHTO T59 EN 1431 ASTM D6997
Used to examine the asphalt emulsions composed principally of a semi-solid or liquid asphaltic base, water and an emulsified agent. The apparatus consists of an aluminium-alloy still with ring burner, a glass connecting tube with water-cooled condenser, a graduated cylinder 100 ml cap, support stands, holders and two thermometers range -2 to 300°C.
Used for determining the penetration power of bitumen emulsions.
Standards EN 12849
Used for determining the penetration power of bitumen emulsions.
41.5 mm internal dia., 115 mm approx. total height, fit with glass filter disc pore size between 160 and 250 µm.
This equipment is used for the identification of anionic and cationic bituminous emulsions.
Standards ASTM D244 EN 1430 ASTM D7402
This equipment is used for the identification of anionic and cationic bituminous emulsions used in road construction. For this purpose, it has two electrodes that are introduced into the emulsion, connected to a continuous power supply, in which after a time of passing a current through the emulsion, it can be observed which of them has been deposited a binder film.
Used for determining settling tendency of bitumen emulsions.
Standards EN 12847 ASTM D6930
Used for determining settling tendency of bitumen emulsions.
600 ml capacity, with one division mark at 500 ml. Complete with two closeable side tubes.
