the spherical sand particles are screened and graded by screening and grading of the spherical sand particles no.9 9 (Sep 2014): 3755–3763.Laboratory testing of railway ballast poses practical difficulties because the particle size is often too large for most standard apparatus. There are therefore advantages in developing a scaled material whose behavior is representative of the full size material. A first stage in validating such an approach is to investigate whether the particle shape is affected by the change in scale.Natural Aggregate. Using natural rocks (such as limestone

and railroads. It is widely available in quarries across the country.The crushed sand is manufactured by crushing diabase rock. The sieving curve in Fig. 1 shows that the particle content with size of 2.36–4.75 mm is the highest 63 and 100 mm is used on roads or driveways to bridge over muddy and standing water conditions. ...
