Laboratory characterization of the load transfer-crack width relation for innovative short concrete slabs pavements

Aggregate interlock is the dominant load transfer mechanism in non-dowelled Jointed Plain Concrete Pavements, as the innovative short concrete slabs. Although the Load Transfer Efficiency of this pavement innovation is based on that mechanism, the structural design methods do not relate the Load Transfer Efficiency by aggregate interlock with...

The effects of the early-age concrete behaviour on the in-service performance of Jointed Plain Concrete Pavements

For their characteristics, concrete pavements are particularly valuable in critical traffic hubs as intersections or roundabouts, roads with predominant trucks traffic or bus corridors, bus stops, bus stations, industrial floors, yards and airport aprons. In particular, in Jointed Plain Concrete Pavements (JPCPs) cracks are produced under the...

Uncracked joints in plain concrete pavements: causes, effects and possibilities of improvements

During the construction of Jointed Plain Concrete Pavements (JPCPs) in Chile, it was observed that joints remained uncracked. The objectives of this paper are to evaluate the effects of uncracked joints (UnCrJ) in JPCPs and to propose possible solutions or improvements to avoid or minimize this phenomenon. Considering low thermal amplitude as...

Functional thresholds for designmaintenance of urban pavements: Functional criteria for sustainable design of urban pavements

Functional criteria have been mostly defined in urban pavements using subjective methods, rather than by means of objective and repeatable procedures. The Whole<br/>Body Vibration, the Heart Rate Variability, and new technologies to determine the<br/>IRI (International Roughness Index), are nowadays available. For that, an analysis of<br/...
