FIBROUS CONCRETE EXPERIMENTS SHOW PROMISING FIGURE AS PAVING MATERIAL

THE U. S. ARMY'S CONSTRUCTION ENGINEERING RESEARCH LABORATORY HAS BEEN CONDUCTING A SERIES OF TESTS AT THE ARMY'S WATERWAYS EXPERIMENT STATION, VICKSBURG, MISS., ON THE PREFORMANCE OF FIBROUS CONCRETE. THIS CONCRETE IS PORTLAND CEMENT CONCRETE MIXED WITH SHORT STEEL FIBERS RANDOMLY DISPERESED THROUGHOUT. IT WAS DESIGNED BY THE UNIVERSITY OF ILLINOIS IN CONJUNCTION WITH THE U. S. STEEL CORP.; ACCORDING TO RESEARCH ENGINEERS THE MATERIAL PROVIDES BETTER RESISTANCE TO CRACKING SINCE IT IS REINFORCED THROUGHOUT AND OFFERS INCREASED FLEXURAL STRENGTH AND FATIGUE ENDURANCE. THE TESTS AT THE WATERWAYS EXPERIMENT STATION HAVE CONSISTED OF 4,500 LOADINGS BY AN APPARATUS SIMULATING ONE 12 WHEEL GEAR OF THE C-5A AIRCRAFT LOADED AT 30,000 LB/WHEEL. THE FIRST CRACK APPEARED AFTER 1,000 LOADINGS. ANOTHER EXPERIMENT IS UNDERWAY TO ACTUALLY TEST THE PERFORMANCE OF FIBROUS CONCRETE PAVEMENT AT THE TAMPA INTERNATIONAL AIRPORT, FLORIDA.
