In a study conducted by Robert et al. [42] found the k 1 value in the range of 8–15 mPa and the k 2 value in the range of 0.55–0.65 for crushed-stone materials used in the base course. Sweere [43] and Robert et al. [42] emphasized that k 1 parameter is more important in determining material quality compared to k 2 .

The graph bars on the material properties cards below compare granite to other natural stone materials (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on. Mechanical Properties. Compressive (Crushing) Strength. 2200 MPa 320 x 10 3 psi ...

However, it was also revealed that Aggregate Impact Value (AIV) is 14.3%, Aggregate Crushing Value (ACV) is 21.7%, flakiness and elongation indices for the aggregate granite are 24.9% and 28.1 % respectively. In addit ion, the force or load required to produce 10% fines was estimated to be 184.86kN. Therefore, the results of

Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the ... Polished Stone Value (PSV) – this is a measure of resistance to the polishing action of tyres (Figure 4). It is increasingly important as skid-free roads ...

Explanation: The polished stone value test is used to test the abrasion of the pavement. It gives a measure of the friction in the pavement also. ... Explanation: Aggregate crushing value is found as the percentage ratio of the weight of the sample passing the sieve to the original weight of the sample. So, the aggregate crushing value for the ...

Observations of Los Angeles Test Original weight of aggregate sample = W 1 g Weight of aggregate sample retained = W 2 g Weight passing 1.7mm IS sieve = W 1 - W 2 g Abrasion Value = (W 1 - W 2 ) / W 1 X 100 Results Los Angeles Abrasion Value = Recommended Los Angeles Test Values for Pavements Los Angeles test is commonly used to evaluate …

Because granite is rarer than ceramics or other man-made materials, laying granite flooring can greatly increase the value of large real estate, and natural granite countertops have unique temperature resistance, which is the choice for various types of board processing. ...
