The world-wide debate on suitable economic measures to improve mobility and energy efficiency has also led to the development of new and innovative construction materials and methods as a way of solving the problem of how to pave roads and trafficked areas economically. One such innovation is paver-compacted concrete, or...
Concrete Pavement in the Streets of Access to Paranaguá Port in the South of Brazil Portside Area Revitalization
The objective of the concrete pavement construction design of the main access streets to all Paranagua Port Terminals was to improve the traffic of trucks which transport goods being imported into and exported out of Brazil. Concrete pavement was the final engineering design chosen for this job due to the...
Roller Compacted Heavy Concrete (RCHC) for Pavement Strength and Density
In the technology of the Roller Compacted Concrete (RCC) for pavement, various types of aggregations are used classically as aggregates, such as the crushed and the rolled aggregates limestone and siliceous, giving concretes with a relative density in the order of 2200 to 2300 kg/m3. In the present work, we...
A New Design Method of Concrete Pavements
In this paper a new design method of plain concrete pavements without bond to the subgrade is presented. For the first time, stresses resulting from environmental conditions will be considered in a realistic way in addition to stresses due to live loads. The basis of this new design method is...
CRCP a Cost-Effective Long-Life Pavement Solution for Highways & Expressways
Continuously Reinforced Concrete Pavement, CRCP is a concrete pavement that is reinforced with steel bars in the direction of traffic. CRCP is a durable pavement solution, advancement to plain concrete pavement. Reinforcement is used in CRCP, to tackle the problem of concrete slab cracking, instead of joints used in conventional...
Guidance to Quality Management of Road Construction
The purpose of this article is to provide the administration and the designers with an effective, workable flow-chart so that the quality of the road is priority number one and that the execution problems are manageable. Based on the experience during most recent jobs COPRO observed interesting evolutions and missing...
New Innovative Road Construction Method Whitetopping a Quick Way to Resolve Rutting
Road traffic in Germany is increasing steadily year after year and recent forecasts have predicted that it will continue to do so. At the same time, neither the German central government, the federal states nor the towns and cities have the funds required for new infrastructure projects and urgently needed...
Storage and Infiltration of Rain Water Through Permeable Paving Blocks a First Step to Disconnect – Results of a Belgian Research Project
Water-permeable paving is used to minimize the far-reaching adverse effects produced by sealing off the natural water balance. The risk of flooding during thunderstorms by water running off the surface or by overflow from sewer pipes is strongly reduced by the immediate absorption and subsequent storage of water in the...
Long-Term Performance of Low-Noise Concrete Pavements
Traffic noise is one of the major environmental concerns within the countries of the European Union. 80 to 90% of the traffic noise pollution is generated by road traffic. The major part of the noise emitted by vehicles on roads in the mid- to high-speed range is nowadays due to...
The Frost-Resistance within the Drainage Concrete
Drainage concrete on the base of cement with BD10 admixture was analyzed in our research. The paper presents components of mixture, experimental results of thaw and freezing tests and compression strength for drainage concrete. The specimens were fabricated in Poznan University of Technology laboratory. All specimens were prepared as drainage...
Composite Pavements Restoration of the E411 and E25 Motorways in the Province of Luxemburg (Belgium)
The composite pavement concept can be described as an association of bituminous layers or modular elements with cement concrete. The desired objective is the association of two or more layers of a different nature in such a way that the specific advantages of both types can be profited from thus...
Concrete Pavements on Bridges
Pavements on bridges are a very problematic element for each road administration. Classic European solution, concrete bridge deck with waterproofing membrane and pavement with asphalt wearing course, makes a lot of problems with maintenance, road closures etc. The paper presents results of research in the field of concrete pavements on...
