Abstract
An aggregate material spreader which is suitable for spreading aggregate material especially concrete on driveways, roadways and other paved surfaces. Work is performed by a roller-skid assembly adequate for rolling on forms and also skidding on the ground. It may have a built-in vibrating system and screed plates to grade material off at a desired level. Because of the skid embodiment it is designed to slip form. Finally a gliding float moves over the surface smoothing out all wrinkles. Also an alternate embodiment exists with a hopper built above the spreader with a sloping top attached on at the rear of said hopper at a lower position for concrete to discharge through for a finished product.
