In the sixties and seventies it used to be the traditional way to build paved country roads in full width in rural road construction. Economical consciousness, agricultural production zones -in the context of developing better economical systems-forced us to change our views. A very natural path is a wheel-track path...

Behaviour of Rolled Compacted Concrete Results of Measurements in Experimental Pavements
Precise measurements on experimental ruil scale pavements demonstrate that curling and warping phenomena arc affecting similarly the RCC and the conventional PCC pavements of equivalent designs: with «light differences in deflections and joint openings mainly attributed to different adherence at the slab-base interface. After IS months exposed to drying shrinkage....
The Influence of Dowel Deviation on Concrete Paving Slabs
A series of tests have been carried out to figure out the in-fluence of deviation of the dowels on concrete paving slabdowels with respect to slab movements through shrinking andthermal variations.The stresses produced in the slabs for various deviations withrespect to the theoretical position and according to the systemchosen to...
Study of Long-Lasting Materials and Conventional Paints on Concrete Surfaces
Due to the increase of concrete use in road cons-truction, the report examines the influential fac-tors on the three most important properties in roadmarking, above all on concrete pavements.The analysed properties are:- Night visibility.- Day time visibility.- Skid resistance.The study makes a comparison of two systems:two components system (plastic of...
The Use of Steel Fibre Reinforced Concrete in Heavy Duty Port Pavements
Recent years have witnessed a considerable growth in importance of heavy duty pavements, mainly because of several major pavement failures in ports leading to serious problems. A recent development took place in the concrete technology and has considerably increased the cost effectiveness and performance of concrete heavy duty pavements making...
Experimental Study of the Strain Modulus of Compacted Concrete
In this paper the results of several experimental studies carried out in order to determine some properties of RCC are described. These properties are important to design and to control RCC pavements: - comparison between strain modulus of different RCC and vibrated concrete mixes whose mechanical strength were similar; proposal...
Considerations in the Design of Jointed Concrete Pavements
This paper provides considerations, recommendations, and guidelines on the design of jointed concrete pavements. These are based on the field performance results of 95 inservice con-crete pavement sections, on the results of a literature review,and on the experience of the authors. Key considerations in thedesign of concrete pavements are highlighted...
Concrete Paving in the UK One Contractors Experience and Approach Since 1983
dfred McAlpine Construction Ltd have constructed 20 kilometres of concrete carriageway using slipform pavers; 00 kilometres of which have been completed since 1983. This aper sets out the philosophy and experience of this firm with egard to the construction since 1983. It highlights the decision laking processes undergone at tender...
Optimizing the Surface Texture of Cement Concrete Roads
The growing concern about the influence of the road surface on traffic noise raises the problem of reducing the noisiness of cement concrete roads whilst keeping high skid resistance values. Studies on various aspects of tyre/road interaction con-ducted in the past ten years at the Belgian Road ResearchCentre provide basic...
Light-Traffic Roads in France Towards New Practices
Decentralization has brought about significantly renewed interest in France in investments for regional and local roads, their rehabilitation and maintenance. Many methodological tools have been developed in the past 10 years to prepare and accompany these trends in areas in which cement concrete had played a sinall relative part in...
A New Design Method For Control of Cracking in Continuously Reinforced Concrete Pavement
Reinforcement stress and crack width has been in-vestigated in full scale experimental pavement ofContinuously Reinforced Concrete Pavement forthree years. The validity of designequation for pre-dicting crack width distributed through the thick-ness of the slab and reinforcement stress etc.,which is based on bond stress -slip relationshipconsidering the effect of both concrete...
A Contribution to the Study of Joints on Concrete Pavements
vlaterials used as joint sealants on concrete pavements are zenerally classified in: - Preformed sealants. - Field molded sealants. l'his work shows the demanded characteristics for preformed .ealants and field molded sealants. The last ones are divided in :wo types: thermosetting -two component systems- coldap-rlied, and thermoplastics --one component- bot...
