Evaluation of Silica Fume High Density Thin Bonded Overlays (FHWA-OK-02-2 2132)
(2002-9)
Aggregate base is an important component of a pavement structure. It supports the asphalt concrete (AC) layer and reduces the wheel load-induced stresses on the underlying Microsilica fume, commonly called silica fume, is ...
Experimental determination of the ultimate capacity of a composite prestressed bridge unit (FHWA-OK-89-05) 2162
(1989-12)
A 55 ft. long prestressed, composite steel girder-concrete slab bridge unit was tested to ultimate load. The unit had previously undergone a series of tests including sustained loading, fatigue loading, and static loading ...
INVESTIGATION OF OPTIMIZE GRADED CONCRETE FOR OKLAHOMA - PHASE 1 (FHWA-OK-13-12 2160)
(2013-10)
Optimized Graded Concrete has been a subject widely discussed through the history of concrete. Since aggregates make up over 70% of the volume in a mixture, gradation is critical to the strength, workability, and durability ...
