New Developments in Rapid Set Concrete Slab Replacements
Current and future eras are seeing an operational environment where road occupancy for pavement maintenance or repairs will be severely restricted under conditions of maximising availability for service traffic and access to roadside properties. A key driving force for concrete pavement slab replacement, where required, is the need to use...
Latest Developments for Roller Compacted Concrete (RCC) in USA
Roller Compacted Concrete (RCC) is a no slump concrete that is placed by a high density paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards and manufacturing plants. This paper will summarise a recent...
Design Of Ultrathin Fiber Reinforced Concrete Pavements
A new methodology has been developed to design the concrete slab thickness by optimizing the slab size given the geometry of the truck axles, the design is based on an unbonded system with either granular, HMA, Stabilized or Concrete Base. The key principle of the design method is to configure...
