In this paper, delamination formation is investigated. Stresses due to temperature and moisture variation are considered within the scope of the formation of the delamination. Tensile and shear stresses are determined numerically based on finite element analysis using simulated pavement moisture data. A finite element program is developed to allow...

The space available on our roads is becoming less and less. All forecasts agree that the increase in traffic will also cotiliiiue to grow considerably in the years before us. At the same time, because of the changes in political conditions in Europe and the opening of the frontiers, there...

Cement treated asphalt mixtures (CTAM), which are composed of an asphalt mixture and cement milk injected into voids of the asphalt mixture, were studied for use as a fast overlay material for airport pavements. The cement milk must have adequate fluidity for about 30 minutes and must develop a flexural...

To the North of Gent there is an important harbour and industrial zone. Because of the heavy traffic on the road connecting Gent and Zelzate (R4, section J. Kennedylaan), deep ruts have formed in the asphalt pavement, mainly at the junctions. In order to repair these ruts in a durable...

For the year-long approved concrete safety barriers, produced of in-situ concrete or prefabricated units, the new EN 1317 part 1 will discribe the general criterions of the test methods in the future, and part 2 the performance classes and acceptance criteriOns. The opening of the European Market has consequences for...

Mix-in-Place Recycling with cement stabilization is an economical and environmentally friendly method for the reconstruction of damaged asphalt roads and ways. The most remarkable characteristic of this method is that the entire existing road construction material can be used again for the new road pavement. This essay contains descriptions of...

In this paper some roads and industrial pavements where "semi-continuous concrete" was employed are prcscntcd as well as cost and performance under several conditions.

Increasing traffic loads and new environmental criteria have led to more stringent requirements for the surfacing of roads. At the same time, practical experience and new methods have improved the construction of concrete road surfaces. In the light of these developments, it was also necessary to adapt the German technical...

Many areas in western Europe suffer trom congestion of traffic during peak hours, mainly on motorways leading to and situated near the economic centres. Therefore, authorities plan to widen several motorways in order to improve the mobility. In the Netherlands the widening of approximately 400 km motorways is expected to...

Waste disposal is a serious problem for local authorities and the search for alternative solutions which allow for reusing is necessary. rin public works on roads or sewer systems,new techniques, new types of materials and new approaches are coming to the front, including the consideration of "environmental costs" besides technical...

Two test sections were constructed with a base course of porous concrete under the emergency lane of a motorway. This base composed of new aggregates or recycled aggregates, has the strength of a cement treated base and the function both of bearing capacity and drainage. Mixed in Plant and placed...

Roller compacted concrete (RCC) pavements are expected to be an economic and rational concrete pvPmAnt system that will become increasingly popular in Japan. The maximum thickness of a RCC slab completed in one layer is limited to 25 cm because of limitations in the compactability of the concrete and the...
