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...
France Fifteen Years Review on the Behaviour of Composites Pavements Concrete on Asphalt Mix
On the initiative of concrete road professionals on the one hand the French cement industry represented by its trade association CIMBETON and concrete pavement construction companies represented by the trade association SPECBEA and the French road administration represented by SÉTRA on the other hand, a new concrete pavement...
Classification and Methods for Rehabilitation of Concrete Pavement- a Spanish Example
Highways superficial rehabilitation appears nowadays as one environmental friendly option to increase the service life of pavements. The remaining structural section is responsible for providing enough resistance for the ongoing traffic loads. The basic goal of this kind of treatments is to recover a certain level of comfort and security...
In-situ Architectural Concrete and Pre-Dosed Micro-Concrete for Wear Thin Layer Pavements in Urban Areas Diogo Menezes Square as an Example of Environmental Renovation
In this communication the development of non traditional-solutions for pavement surfaces will be assessed, by the use of colored pre-dosed micro-concrete or in situ concrete in thin layers of high performance architectural applications for urban, pedestrian, cycling and roads. This assessment will be focused on frequently technical constructive barriers inherent...
Slab Curling and Rolling Resistance
In a life cycle analysis a higher investment 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 footprint. To further improve the sustainability of PCC pavements the rolling resistance should be...
How to Build Smooth Concrete Roads and Measure Success the Moment You Pave
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...
Concrete Roads in Poland the Case for Selling Non-Mainstream Infrastructure Technologies
The paper illustrates, on the grounds of Polands case, the concrete roads network development in a jurisdiction dominated by asphalt roads. The author reviews typical drawbacks apparent when promoting concrete roads, and identifies several most arresting phenomena that have led to the current technological stalemate. The goal of the paper...
Precast Concrete Pavement Innovations, Performance and Best Practices
The precast concrete pavement (PCP) technology is gaining wider acceptance in the US for rapid repair and rehabilitation of concrete pavements as well as for heavily trafficked asphalt concrete intersections. Although the US PCP technology is of recent origin, with projects less than about 12 years old, many projects have...
Abrasion Resistance and Transport Properties of Road Concrete
Abrasion resistance and impermeability are vital in road concrete. In this experimental study the compressive strength, abrasion resistance and transport properties of the road concrete were investigated. In order to study transport properties, water sorptivity and depth of penetration of water under pressure were taken into consideration. For this purpose,...
Design & Construction of an Experimental Two Layer Concrete Pavement Motorway Section in Spain
In June 2006, GISA a Public Company, within the Department of Planning and Public Works of the Catalonian Regional Government, awarded CEDINSA the concession for the project of constructing and operating the projects of converting into a dual carriageway the stretch Vic-Ripoll of the C-17 highway. As a participant in...
Modular Security Barriers for Urban Demands Current and Demands State of the Art Solutions
Using appropriate security barriers for directing the traffic in urban areas, close to downtown, shopping centers, protecting working zones in urban areas in general, and separating traffic, is essential for the safety of different traffic users. The traffic flow at industrial, commercial and public areas is easily managed by using...
Experimental Study of Properties of Pervious Concrete Used for Bridge Superstructure
One of the main advantages of pervious concrete is its ability to drain water easily. Moreover, ear-lier studies on pervious concrete have shown that it can be designed to perform well in freeze-thaw regions. Bridge superstructures placed in regions where the temperature during winter time varies around freezing point are...
