Investigation of Longitudinal Cracking in Widened Concrete Pavements

Joint Deterioration in Concrete Pavements

Concrete pavements located in cold climates have been experiencing premature joint deterioration. Entrapment of moisture in the joints saturates the surrounding concrete, rendering it susceptible to freeze–thaw damage. To identify and to isolate the variables that might be causing this localized deterioration, concrete cores were obtained from deteriorated and non-deteriorated sections of US 35...

Evaluating Cracking In Concrete

FRP Dowels for Concrete Pavements

A Paper for the World Wise Conference 1999 Winnipeg, Manitoba © November 15, 1999 Introduction Joints are used in concrete pavements in order to control cracking due to thermal and environmental conditions. Dowels span joints to transfer load from one slab to an adjacent slab and to provide vertical and horizontal alignment. Currently, smooth epoxy coated steel dowels are placed across transver...

Experimental Investigation of Corrosion Cracking in Reinforced Concrete Beams Containing Nano Wollastonite

Cracking of the concrete cover due to corrosion is defined as the serviceability limit state of reinforced concrete structures. This study evaluated the influence of a mineral admixture i.e. nano wollastonite on corrosion performance and serviceability of reinforced concrete structures by performing an accelerated corrosion test on ten reinforced concrete beams under a sustained load. To do so,...
