Lastly, the weight per foot of the concrete roadway is determined by multiplying the roadway thickness (RT) in feet times the portion of the roadway carried by a single girder, BWG, times the specific weight of concrete. This gives a contribution to the distributed load, w, as: (8.10)wro...
The apron is the section connecting the driveway to the finished roadway. This means that it likely crosses the sidewalk area. It typically measures the driveway’s width by between 8’ and 15’ long. Some are small, while others are much longer. They have the same costs per square foot...
1. The method of forming contraction joints in concrete roadways which comprises setting up crosswise of the roadway, prior to pouring, a contraction joint assembly having a series of spaced load transfer expansion joints with a transversely extending dividing plate supported thereon, slidably disposing...
In 2012, Roller Compacted Concrete (RCC) pavement was used to rehabilitate a deteriorated section of roadway in the Fayetteville Shale Play Area (FSPA). Due to recent heavy truck traffic related to natural gas exploration efforts in Arkansas, the FSPA has experienced significant pavement distresses...
As the number of heavy vehicles on the road continues to increase, collisions involving heavy vehicles and concrete median barriers (CMB) occur more frequently than in the past. Consequently, there is a growing need for research into more stringent desig
FIG. 6 is a vertical section illustrating a concrete slab overlay formed with an integral anchoring channel in accordance with another embodiment of the present invention. DESCRIPTION OF THE PREFERRED EMBODIMENTS In the example shown in FIG. 1, a bridge deck is illustrated as typical, but it sho...
The fiber-reinforced concrete specimen is a typical strain rate-sensitive material. Under the condition of dynamic loading, the damage stress state of the fiber-reinforced concrete test blocks is no longer similar to the conventional quasi-static state. For example, under the conditions of high-...
For typical configurations of the joint, current design practices however rely largely on the judgement and experience of individual designers, using existing knowledge of reinforced concrete and structural steel joint design [23]. The traditional separation between structural steel and reinforced concrete ...
The typical shear rate values corresponding to each step are given in Table 7.2 (Roussel, 2006b). As already discussed, the fact that mixing intensity (or more generally the flow history) affects rheological properties (Tattersall and Banfill, 1983; Williams et al., 1999; Juilland et al.,...
