Dewayne was an innovator and creator at coronary heart. He was named on over 100 U.S. utility and design patents over his years, main product growth at AEC. Allen was at all times difficult the established order and searching for a greater strategy to place, end, or pave concrete. Dewayne beloved concrete as a constructing materials and the concrete trade as a complete. His ardour was serving to concrete contractors enhance their craft with machines that made their jobs simpler and their completed product higher. He can be remembered by many as a instructor and mentor of contractors who in the present day produce among the greatest concrete flooring and pavements on the planet. 

A civil engineer by training, Allen labored on the development of interstate highways in Missouri and Illinois within the late 50’s and early 60’s. In 1964, Dewayne began Allen-Hardin, Inc. which was a ready-mix concrete operation in his hometown of Piggott, Arkansas, together with his spouse, Mary Ann. This firm grew and adjusted over time to ultimately turn into Allen Engineering Company after working quite a few vegetation in Northeast Arkansas and Southeast Missouri. 
 
In 1977, Dewayne designed, engineered, and manufactured his first piece of concrete tools: the Allen Razorback Truss Screed. Underneath Allen’s path, AEC grew and developed a full line of concrete tools starting from walk-behind and ride-on energy trowels to triple tube curler pavers.  
 
Allen was instrumental within the evolution of the flat and stage concrete flooring within the late Nineteen Eighties and early Nineteen Nineties. Dewayne was the primary designer to place clip on float discs (pans) on journey on energy trowels within the USA. This mix of using trowels geared up with float pans drastically improved the flatness of concrete flooring as measured by F Numbers. These riders with pans together with laser guided concrete screeds revolutionized the development of flat and stage concrete flooring within the USA and world wide. Allen’s contribution to the event of flat and stage concrete flooring was acknowledged with the distinguished Sam Face Golden Trowel Award. 
 
Allen is survived by his spouse, Mary Ann; his two sons, Jay and John; and 7 grandchildren.
