For particle size, as particle size increased, the reaction rate decreased. The reaction rate was about two times faster for the broken particle. The activation energy was found to be 430.53 J/mol. The data was pretty linear and the line of best fit was found relatively easily.

The experimental results demonstrated that filler particle size exerted a significant influence on the fatigue lives of bituminous mastics. When applied in terms of initial shear strain levels, the fatigue lives for both un-aged and aged mastics were ranked in descending order of filler particle size (F1, F2, and F3).

Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. Sand, as you may guess, forms sandstone. Sandstone is medium-grained, meaning its fragments are between 1/16 mm and 2 mm. Silt forms fine-grained siltstone, with fragments between 1/16 mm and
