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...
Classification and Methods for Rehabilitation of Concrete Pavement- a Spanish Example
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....
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...
Improvements to the Construction Process for Semi-Rigid Pavement Rehabilitation on Mexican Highways
The Mexican Federal Government has allocated a great deal of investment to the maintenance of pavements across the existing road network (in 2010 and 2011, this investment amounted to 7,860M and 7,894M respectively). During the 1990s, a pavement system was introduced in Mexico involving the incorporation of Portland cement using...
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...
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...
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...
Optimization of the Recycling of Concrete in Concrete Application to an Airport Slab
The use of demolished concrete as recycled aggregate in new concrete is a promising solution within the context of sustainable development. However, this application is still limited in the construction sector due to the lack of knowledge. In that context, Ifsttar (France) and the French industry's major players have finished...
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...
Surface Grinding Concrete Pavements
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...
Progressive Composite Bridge Construction with Cement Concrete Pavement
The project deals with research on effective composite steel and concrete bridge structures, profiting from directly running cement concrete pavements. The aim is an innovative layout solution, technology of construction and maintenance and research of new formulas for concrete parts which will lead to lower collective costs of production and...
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...
