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...

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...

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 ALDOT’s Life Cycle Cost Analysis (LCCA) methods for comparing asphalt and concrete paving alternatives. Auburn was asked to address LCCA from...

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,...

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...

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...

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...

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...

For networks owners, like the French national gas utility, it is essential to ensure a rapid access to their installations, even with a simple pick, for normal or emergency maintenance matters. Modular concrete pavements were developed during the last years for that purpose. In order to keep their stability, the...

The paper describes the actual possibilities of using concrete pavement in a roundabout. Concrete may be better material for aprons than conventional cobblestones. It can be better for both durability of the road and for road safety. If heavy vehicles often pass through the cobblestone pavement in the apron, the...

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...

Life Cycle Cost Analysis (LCCA) evaluates the economic performance of alternative pavement investments. Currently, practitioners treat input parameters as static, deterministic values, which although computationally simpler, will hide the implicit uncertainty underlying the analysis. Over the past decade, an emphasis has been placed upon accounting for uncertainty by treating input...
