The joint system presented herein takes advantage of the natural development of shrinkage in concrete to induce the formation of joints along the projections of previously placed system devices. Such system induces in an in-situ concrete pavement an efficient interlocking indentation among the slab elements resulting from the shrinkage phenomenon....

In 2005, a forensic engineering study was conducted on a recently constructed concrete pavement located along the Pan-American Highway (CA-1) in El Salvador. The primary distress was observed to be full-depth cracking, predominantly in the longitudinal direction. This type of cracking was noted to occur just a few months after...

The lack of quality data that relates tire-pavement noise to the texture of concrete pavements has hindered the pavement community in both understanding the phenomena and finding ways to minimize its impact. The National Concrete Pavement Technology Center (USA), the US Department of Transportation Federal Highway Administration, and the American...

Continuously reinforced concrete pavement (CRCP) has been constructed on major highways in several countries since the 1940’s. A large majority of these pavements have carried very heavy truck traffic but required low maintenance. Some have experienced problems due to inadequate design, support, and construction. This paper focuses on factors that...

A new concept of concrete pavement have been imagined and tested in France since 1998. It consists in a base layer of continuously reinforced concrete, bonded with a foundation layer of asphalt concrete. The stiffness of the asphalt material and its bonding with the concrete layer contribute to rigidify the...

Road traffic in Germany is increasing steadily year after year and recent forecasts have predicted that it will continue to do so. At the same time, neither the German central government, the federal states nor the towns and cities have the funds required for new infrastructure projects and urgently needed...

The world-wide debate on suitable economic measures to improve mobility and energy efficiency has also led to the development of new and innovative construction materials and methods as a way of solving the problem of how to pave roads and trafficked areas economically. One such innovation is paver-compacted concrete, or...

In situ Concrete Step Barrier provides one of the SAFEST BARRIER solutions for central reserves on road networks because of its almost unique ability to contain heavy vehicles without deformation and thereafter to require NO MAINTENANCE with associated road narrowing and the resulting traffic congestion. The development of Concrete Step...

Modieslab, a recently developed innovative and settlement-free precast concrete pavement structure, with a twin-layer porous concrete wearing course, was tested for its functional and structural properties on two full scale test pavements. Some functional properties, e.g. noise reduction, were very satisfying, however the resistance to raveling and especially the skid...

This document describes the design and construction of the concrete pavement for the relatively steep access ramp bridge of the PEZA truck holding area of the Bale-Weil customs facility. The pavement design takes into account the expected change in usage after 2008 as a motorway offramp and harbour access route....

In 1999, a 60 000 m2 large concrete pavement was completed in a Swedish harbour. The largest part of the area consisted of 200-210 mm thick plain jointed concrete pavement (PJCP) overlaying an old asphalt pavement. The design was based on certain prerequisite concerning traffic loads, i.e., axle loads and...

The pavement is the main and the most important component of a road. Pavements play a major role in the construction cost, maintenance and rehabilitation, traffic quality, vehicle and user costs. They are mainly divided into two types: asphalt concrete and cement concrete. For decision making in choosing the pavement...
