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...
France Fifteen Years Review on the Behaviour of Composites Pavements Concrete on Asphalt Mix
Rapid Repair of Concrete Roads using Calcium Aluminate Cement Based Mortar in Winter Conditions
Calcium aluminate based mortars have been widely used for fast setting repair applications. This article will present the laboratory work that was conducted to repair an existing concrete road in Istanbul. The main damage mechanism was both abrasion and frost damage; the maximum time that the road can be closed...
Evaluation of Excavatable Cement Treated Materials for Urban Areas
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...
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...
Recent Developments in the Design and Construction of CRCP Towards a More Durable Concept
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,...
Noise Emission of Concrete Pavement Surfaces Produced by Diamond Grinding
In Germany, diamond grinding is frequently used to improve the evenness and skid resistance of concrete pavement surfaces. Since diamond grinding has been observed to affect tyre / pavement noise emission favourably, the relationship between surface texture, concrete composition and noise emission of concrete pavement surfaces has been systematically investigated....
The New Balastless Track Project from Idea to 1km Prototype
Within the frame of a French collaborative research program started in 2007, private companies, a public research laboratory and a rail network owner have jointly developed a new ballastless track structure (NBT) based on independent concrete slabs. This structure is dedicated to both very high speed operations and mixed passenger/freight...
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,...
Heated Transportation Infrastructure Systems Existing and Emerging Technologies
Ice and snow on pavement surfaces cost the U.S. national economy in snow removal, damaged pavement and lost man-hours due to travel delay. Common practices for removing ice and snow from pavement surfaces include spraying anti-ice chemicals on the ground and deploying snowplowing vehicles. These methods are labor-intensive, occasionally ineffective...
Texture and Noise Characteristics of Exposed Aggregate Concrete Road Surfaces
Exposed aggregate cement concrete (EACC) road pavements are used on a large portion of the Austrian federal motorway network due to their durability and reduced noise emission. The standardized types with 8 and 11 mm chipping sizes have been characterized due to their noise emission and are subject to approval...
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...
Comparison of Two Rehabilitation Worksites of Motorways Single Versus Double Layered CRCP
The technique of continuously reinforced concrete is used in Belgium for the construction or rehabilitation of heavily trafficked motorway sections. Since a few years, double layered CRCP is being considered in order to improve the rolling noise characteristics of the surface. In this paper, two worksites where CRCP was used,...
