CONSISTENCY TEST FOR MICRO SURFACING

Method for Determination of Consistency, As per IRC:SP:100-2014, Appendix-3

Scope :  

This Test is used to determine the consistency of slurry seal and micro surfacing mxture.

Apparatus :

Mould of metal, in the form of a frustum as a cone, 38 mm in diameter at top,89 mm in diameter at the base and 76 mm in height. The centre of 228 mm metal plate is inscribed with a circle of 89 mm in diameter. Three to four additional circles each 13 mm greater in diameter than the preceding circle are inscribed on the metal plate around the centre.

Method :

Mould is loosely filled with slurry seal/microsurfacing mixture and struck off. The mould and contents are then inverted in the centre of the metal plate by placing the inscribed surface of the metal plate on the slurry filled cone, which while holding cone and plate firmly together, is quickly inverted. The mould is removed and contents allowed to flow over the inscribed circles until flow of the slurry stops.

Report :

The outflow of slurry is measured at four points 90° apart from each point. The average value is reported in cm.
