Road users and transportation agencies are the largest groups of clients for pavements. Both assign priority to the functional pavement condition and the Joint Faulting (JF) is directly related with this condition. An alternative to the traditional design of Jointed Plain Concrete Pavements (JPCPs) is the short slabs. The objective of the present paper is to compare the JF between traditional JPCPs and short concrete slabs. This comparison is made using an available deterioration model and JF trends observed at sh...

The Jointed Plain Concrete Pavements (JPCPs) can resist high traffic demands without invasive maintenance interventions that produce delays, discomfort and even can affect users safety. However, sealing the joints of JPCPs and keeping them sealed for 10 years, costing up to 45% more than the Unsealed Joints (UnJs). As in addition the joint seals are not working well enough there is an increasing interest to eliminate them. The Wisconsin Department of Transportation (WisDOT) has reported savings of 6,000,000 US dol...

An urban arterial, collector or local street must be geometrically and functionally designed, i.e. not only considering the occupation of the physical space but also the capacity and level of service provided, that is directly related with the perception of the user. The pavement is an element of the urban infrastructure that also has a fundamental effect on the perception of the user, for instance on the ride quality (regularity and skid resistance of the surface), visibility and especially on the interventions f...

Since early age, the concrete experiences deformations due to thermal differences and shrinkage. The Jointed Plain Concrete Pavements (JPCPs) have joints, these are weak zones where it is expected the cracks will be produced. In fact the designed slab length considers that the joints crack. During the construction of JPCPs in Chile, in wet climatic conditions, it was observed that the joints remained uncracked even 3 weeks after construction. Nevertheless, in average climatic conditions, the cracking time of the f...
