Dry-Batch Pavers Have Their Day

摘要

From the 1910s into the mid 1950s, the dry-batch paver was found on practically any project requiring the placing of concrete pavement and was also used for other large-volume pours, such as spillways and canal linings. These pavers evolved in response to the proliferation of motor vehicles and the subsequent need to pave roads efficiently. Conventional mixers of the day, which were loaded with raw materials on one side and discharged from the other side, necessitated carting mix to the pour, making them unsuitable for road paving. In 1903, The Foote Manufacturing Co. modified a mixer to receive raw materials at one end and discharge out the other, so that the material flowed along the machine's direction of travel. Even though these "pavers" were distinct machines from the side-discharge construction mixer, they often still were called mixers.
