This paper aims to outline briefly the history of the first concrete pavements in Europe and in the United States. The authors will present examples of concrete pavements built in Tarnów, a relatively large city (115,000 inhabitants) in southern Poland. They will show technological and structural solutions for using concrete...

Concrete slit drains (also known as slot drains – see fig. 1,2) are being used for the draining of highways and roads, as well as for large handling and parking areas. Recently, this system of drainage has become increasingly applied, which does, however, bring with it an increased incidence of...

The Strategic Highway Research Program 2 (SHRP 2) recently completed a study entitled, “Real-Time Smoothness Measurements on Portland Cement Concrete Pavements during Construction”. As part of this project, the feasibility of this technology was explored. There was both an evaluation and demonstration of emerging and proven technologies. Model specifications and...

On the beginning of third millennium we, in the Czech Republic, can also notice a big construction boom in the area of bicycle roads and trails. The rehabilitation of existing roads, temporary solutions (e.g. traffic sign placement) overweight the others. Other systematic approaches are also built and they bring a...

The use of continuously reinforced concrete pavement (CRCP) is enjoying a renaissance in the United States (USA). CRCP has the potential to provide a long-term, “zero-maintenance,” service life under heavy traffic loadings and challenging environmental conditions, provided proper design and quality construction practices are utilized. In the USA, the Federal...

Ultrasonic tomography is a non-destructive method to evaluate different characteristics of the pavement such as thickness, position of reinforcement, presence of cracks and impurities, strength evolution. This technique can be used for control and follow-up of new pavements but also for non-destructive analysis of existing pavements in order to determine...

The adoption of electric vehicles (EVs) remains low mainly because of its battery related problems, which include high cost, range limitation and weight. Electrified roadways, which allow EVs to charge while they are in operation (motion or stationary) by using Inductive Power Transfer, is a very innovative technology to overcome...

Road constructions with fibremix concrete allow longer distances between joints, compared to unreinforced concrete pavements. In the absence of a dedicated design tool for fibremix concrete pavements, the search for a maximum crack-free slab length took place in several projects. Fibremix concrete has been used in parking areas near motorways,...

The technique of continuously reinforced concrete for pavement construction is being applied in Belgium since the 1960s. The original design underwent several changes over time, sometimes for economic reasons but mostly in order to improve the long term behaviour of the pavements. Today there are still possibilities for further optimisation,...

Skanska a.s. is one of the leading construction companies, who successfully execute concrete pavement projects in Czech Republic, Slovakia, Poland mostly on motorways and airports. To achieve the best quality, durability and cost-efficiency, it is needed to put an effort to research and development. Recently experts from Skanska are leading...

Concrete pavements are continually subject to the effects of weather and traffic. These may cause tensile stresses at the top and bottom of the concrete road slabs. The resistance of the concrete slab to such effects depends on a large number of factors. In particular, the concrete tensile strength and...

The Belgian standard specifications contain a number of clear requirements for the composition of concrete mixtures and the properties of fresh and hardened concrete. It is generally known that water and air content have a substantial impact on the frost susceptibility of a concrete surface – the former in a...
