Pavement Type Selection: What is the Ideal Process?

Highways Members Only

Pavement type selection is often one of the more challenging and controversial decisions highway administrators face. The process involves weighing engineering factors such as materials, structural, and even long term performance against initial and life-cycle costs to help agencies decide between various pavement alternatives. Given the expenditure of significant public...

Accelerated Full Scale Test on Prefabricated Conrete Slab Pavement for Electrical Supply by Induction of Urban Transport Systems

Highways Members Only

Innovative solutions for transport infrastructure are needed to meet future mobility needs, especially in urban areas. Recently, Bombardier Transportation has developed a new system for supply by induction of electrical public transportation vehicles. It consists in integrating electrical supply cables in a prefabricated concrete slab implemented in the road. These...

A Concrete Cycle Track in the Velodrome of San Vicente Del Raspeig Alicante Spain

Highways Members Only

A concrete cycle track was built in the velodrome of San Vicente del Raspeig, a town close to the Mediterranean Sea in the province of Alicante, in the South East part of Spain. This sport facility was opened in 2013. The cycle track is 7 m wide and 250 m...

Importance of Correct Dowel Positions in Transversal Joints of Rigid Pavements

Highways Members Only

Positions of dowels and tie bars in jointed unreinforced concrete pavements and the importance of their correct placement on pavement behaviour and lifespan was studied as a part of R&D project of Technology Agency of the Czech Republic No. TA02031195 and TE01020168. Laboratory concrete beams with in-built dowels in different...

Surface Grinding Concrete Pavements

Highways Members Only

The report outlines some of the perceptions and issues associated with Concrete roads, and asks if the process of Diamond Grinding is a viable solution to the refurbishment of worn concrete pavements. The paper outlines the process of Diamond Grinding for reconditioning structurally sound but worn concrete surfaces. Gives a...

Belgian Specifications for Freeze-Thaw-Resistant Pavement Concrete

Highways Members Only

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...

Precast Electrified Roadway Pavement Systems using Engineered Cementitious Composites

Highways Members Only

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...

Mixture Quality and Cost-Benefit Analysis of Concrete Overlay Application in Lithuania Pavements

Highways Members Only

Heavy vehicles traffic flow and loads are increasing every year and influence faster degradation of asphalt pavement. A lot of money is expended on distressed pavement repair and rehabilitation, so sustainable pavement structure development is one of priority in Lithuania. Flexible (asphalt) pavement design lifetime is 20 years and often...

A 32-Year-Old CRCP only with a New Porous Asphalt Top Layer still Fit for the Future

Highways Members Only

The A76 is the corridor between the Ruhr area (Germany) and Antwerp (Belgium) in the southern part of the Netherlands. It was built in 1985. Because the asphalt pavement failed as a result of a geological fault in the subsurface, a CRCP with a toplayer of porous asphalt was chosen....

A Dedicated Bus Platform in Castellón Spain

Highways Members Only

The metropolitan area of the city of Castellón, situated East of Spain at the Mediterranean coast, has a network of dedicated bus platforms, which was conceived with two main purposes: to enhance public transport and to structure urban development. As a part of this network, a bus platform, 3.9 km...

Influence of Test Specimen Compaction and Curing Condition for Pavement Cold Recycled Mixtures

Highways Members Only

Presently in most European countries the quality of cold recycling mixtures in pavement rehabilitation is proven by achieving required strength values (indirect tensile strength or compressive strength) and eventually by values of stiffness modulus (IT-CY test method). This empirical approach of quality assessment is quite simple, relatively fast in performance...

Roller Compacted Concrete Pavements for the Urban Environment Turkish Experience

Highways Members Only

Roller compacted concrete has traditionally been used for pavements carrying heavy loads in low speed areas because of its relatively coarse surface texture. However, its use in commercial areas for local streets and highways has been increasing, especially within the United States. Even though Turkey is one of the main...
