The Complete Guide to Crushed Stone and Gravel

Because large stones and quarries are hard on tires, crushed stone was challenging to make and transport until heavy machinery with tracks arrived on the scene. WW2 expedited the development of this type of machinery, and crushed stone began to be used widely in construction projects in the 1940s and 1950s.
