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...

Improving the Rehabilitation Timing and Selection in a Pavement Life Cycle Cost Analysis
Life Cycle Cost Analysis (LCCA) is an economic procedure used to compare competing pavement designs, over a defined analysis period, considering all significant costs expressed in equivalent present value dollars. Currently, most agencies apply a standard, policy set, rehabilitation schedule to all pavements based on historical performance. However, this can...
Comparison of Roadway Jointed Plain Concrete Pavement Thickness Design Methods Common in the United States
While much research in the United States (U.S.) has focused on the development, enhancement, and sensitivity of the AASHTOWare Pavement ME Design (previously known and MEPDG and DARWin-ME) method, little work has focused on comparing the results from this design method to other design methods already regularly used in practice....
Influence of Test Specimen Compaction and Curing Condition for Pavement Cold Recycled Mixtures
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...
A Review of Mechanisms Associated with Premature Joint Deterioration in Concrete Pavements
Premature deterioration of sawn joints has been reported in some cold climate regions in the USA. This paper reviews the multiple mechanisms have been found to contribute to the deterioration. Laboratory and field investigations have shown that freezing and thawing of saturated concreted is a dominant factor. Magnesium and calcium...
Concrete Pavements and Structures for Dedicated Public Transport Lanes
Bordeaux, Clermont-Ferrand, Caen, Grenoble, Lille, Lyon, Marseille, Montpellier, Nancy, Nantes, Nice, Orléans, Rouen, Saint-Étienne, Strasbourg, Paris . Which city hasnt developed or is about to develop its own network of public transport on dedicated lanes? Users warmly welcome this mode of public transport, typical of urban renewal projects for...
Flatness and Levelness of Concrete Pavements for Industrial Areas Requirements and Evaluation Methods
Among various construction activities, related to concrete pavement technologies, an important role is reserved to industrial floors; these structures, in many cases, present the same technical problems of road pavements. Characteristics, construction techniques, exercise conditions, maintenance and control of industrial pavements, in effect, are very similar to the ones usually...
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...
An Industry Perspective to Improve the Life Cycle Cost Analysis Procedure Used for Pavement Type Selection a Case Study for Alabama
At the request of the cement and concrete industry, in 2012 the Alabama Department of Transportation (ALDOT) funded Auburn University and the University of Alabama to recommend updates to ALDOTs Life Cycle Cost Analysis (LCCA) methods for comparing asphalt and concrete paving alternatives. Auburn was asked to address LCCA from...
Impacts of the Longitudinal Joint Location on Slab Stresses
Longitudinal joints in concrete pavements historically have been located along the edges of lane lines, a condition that results in applied loads being located at the most critical points (e.g., edges and corners of slabs). With increasing use of light?colored silicone sealants that contrast less with the concrete surface color,...
A Framework for a New Protocol for Evaluating Concrete Curing Effectiveness
Excessive early early-age concrete surface moisture evaporation can be a source of key issues in the paving of concrete pavemen t, such as plastic shrinkage cracking and spalling related delamination; the use of liquid membrane membrane-forming curing compounds is one of the most prevalent methods to protect hydrating concrete surfaces...
Recent Advances and Uses of Roller Compacted Concrete Pavements in the United States
Roller Compacted Concrete (RCC) is a no slump concrete that is placed by an asphalt paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards, and manufacturing plants. This paper will summarize a recent survey...
