Bituminous cements testing

Mixing stability with cement is the mass of coagulated material (bitumen and cement), which is produced when a bituminous emulsion is mixed with cement under the conditions of the test. 

General and specific requirements for FPC together with minimum test frequencies for FPC, such as equipment calibration requirements, inspection and test frequencies for aggregates, inspection and test frequencies for bituminous emulsions, control of the water, control of the additives (including cement, lime, fibres and chemicals), controls during the process and installation of the slurry surfacing and inspection and test frequencies measured after installation, are given in CEN EN 12273 (2008), Annexes 6.A and 6.B. 

As it can be seen, the structural layer coefficients for the granular base or sub-base layers may be derived from different laboratory tests including resilient modulus (Egg or sb)-Similarly, the structural layer coefficients for the cement-treated bases or bituminous-treated bases may be derived from unconfined compressive strength or Marshall stability, respectively, including elastic modulus.
