Concrete, used in the production of highways and pavements, may deteriorate after many years of service, due to severe exposure conditions. Due to strategic and economic importance of such infrastructures, swift action for repair works is required. Repairs with conventional concrete may take long time for gaining adequate strength, where...

Ice and snow on pavement surfaces cost the U.S. national economy in snow removal, damaged pavement and lost man-hours due to travel delay. Common practices for removing ice and snow from pavement surfaces include spraying anti-ice chemicals on the ground and deploying snowplowing vehicles. These methods are labor-intensive, occasionally ineffective...

For many years, the traffic volumes and percentage of heavy traffic on German roads and motorways have steadily increased and this trend is expected to continue in the future. To guarantee mobility in the future, road construction with a maximum service life and a minimum of necessary maintenance are needed....

The Castilla & Leon Regional Government has built a new road between the towns of Castrofuerte de Campos and Toral de los Guzmanes, located in León Province, in the Northwest part of Spain. It includes a 324m long and 10m wide bridge allowing local traffic to avoid a long detour...

As a proposed long-term pavement solution for bus stops and corridors in highly urbanized areas, four experimental short continuously reinforced concrete pavement (CRCP) sections with different percentages of longitudinal steel were built in São Paulo, Brazil. The pavement sections are only 50 meters long each, a short constructive length in...

The authors present the sustainable pavement design solutions applied on 106 km long section of A2 toll motorway in Poland. For this largest infrastructure project, realized in the frame of Public-Private Partnerships (PPP), the concession model, where the concessionaire has to be paid by public part for the accessibility of...

Portland Cement Concrete (PCC) pavements usually incur higher investment costs than Asphalt Concrete (AC) alternatives. In a life cycle analysis the higher cost is justified by lower maintenance costs, less and fewer traffic flow intrusions, and a longer technical life. All these factors contribute to a reduction of the carbon...

In this study, possibility of top-down cracking in concrete pavement was investigated. The main cause of the crack is supposed to be tensile stress at the top of the concrete slab. 3DFEM simulations that took into account actual temperature distributions throughout slab depth were performed on concrete pavements for a...

Jointed plain concrete pavements curl due to temperature gradients and warp in the presence of drying shrinkage gradients. Since this deformation is restrained by factors, such as the slab self-weight, tensile stresses are generated. Slabs do not remain flat in the absence of daily gradients. This is due to the...

It has been observed by many researchers that the subgrade behavior is load rate dependent. The apparent subgrade stiffness is much higher under the fast moving axle loading than during the slow developing temperature curling and moisture warping. However, traditionally a single k-value is used for both curling and axle...

In 2010 Houben has published a paper on the modelling of the process of cracking at transverse joints in jointed plain concrete pavements (JPCP). Houben uses equations from the standard Eurocode 2 for the time-dependent concrete properties and considers the thermal deformation and the shrinkage (drying and autogenous) for different...

Current pavement design guides for Jointed Plain Concrete Pavements define one critical location at the mid-slab edge and assume that damage accumulates linearly and can be described via S-N curves. More recently, experiments have shown that damage does not accumulate linearly and a pronounced stress range effect exists. These two...
