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...
Continuously Reinforced Concrete on Bridges
As it is well known, in Belgium since the stast of the 1970s, continuously reinforced concrete has to a large extent been used as concrete pavement for motorways. On the bridges, asphalt was sometimes applied, which made it necessary to use expensive anchorages on both sides of the bridges to...
Study of a Romanian Experimental CRCP Road Section
The experimental continuously reinforced concrete (C. R. C. P.) road section has been realized in 1975 on a Romanian principal road, in a mountain area. There are presented the design method, the materials, the technology and the behavior after twenty years of traffic.
Continuously Reinforced Concrete Roadbases
In the Netherlands Rijkswaterstaat is the authority in charge among others of the construction of highways. The department Utrecht of Rijkswaterstaat has chosen a continuously reinforced concrete roadbase for the construction of the 7 km long new highway scction between the cities of Bunnik and I Jtrecht. This choise was...
Evaluation on Serviceability and Durability of Concrete Pavement in Japanese Expressways
Pavement in Japanese Expressways consists of 90% of asphalt pavement and 10% of concrete pavement. The concrete pavement is generally planned to construct because of its high durability and less maintenance cost. The concrete pavement in Tohoku Expressway has been about 20 years in service since its construction. Therefore, including...
The Monselice Experimental Road a Performance Analysis After 5 Years Service
The continuously reitifoteed concrete road executed in Monselice (Padua, Italy) is mainly devoted to heavy traffic. During construction works, the road had been fitted with suitably devised equipment to monitor the operating performance over a sufficiently long time period. The present paper is aimed at gathering significant data recorded in...
A New Approach in Concrete Highway Construction
After a long period of experience in concrete road coad construction a new type of pavement is under supervision. Reasons to develop a new type are some disadvantarous experiences with concrete slabs resting on supporting layer of hydraulically bounded material and the need to reuse old pavement materials. The new...
Hydraulic Concrete Roadways on the Autopista Del Mediterraneo Appraisal and Management
This paper addresses the appraisal and management procedure used for more than 20 years by a toll motorway concessionaire, covering a total of 300 kilometres of concrete dual carriageway built between 1970 and 1985. The system of analysis, surveys and experiments carried out during this period was based on auscultations...
Pavement Performance and Evaluation of a Four Years Old Concrete Road – Study of a Concrete Section of the E6 Road at Falkenberg in Sweden
Interest in concrete roads has increased in Sweden in recent years. Contributory factors are the increased traffic loadings, which demand more rigid types of pavements, and the excellent resistance of concrete roads to wear from studded tyres. This conference paper describes the pavement performance of a four-years-old concrete road that...
Test Method for the Determination of Wear Resistance of Concrete Pavements – a Ring Analysis of Northic Road Simulators
In the European Committee of Standardization (CEN) road simulators have been proposed as test equipment for determining the wear resistance of concrete road surfaces to studded winter tyres. The purpose of this ring analysis was to find what relationship there is between three Nordic road simulators and to produce proposals...
Evaluation Method for Jointed Concrete Airfield and Pavements
In order to harmonize FWD condition surveys on concretee pavements in the Netherlands, CROW's committee UEC1 has developed an structural evaluation procedure for jointed concrete airfield pavements. The committee has developed procedures for in-situ testing and models for determining of the mechanical pavement properties based on FWD measurements. With respect...
Judgment of Compaction Degree of Rccp by Using Acceleration Waves on Vibrating Roller and Influence of Subgrade Bearing Capacity on It
The acceleration wave of the vibrating compactor under work is disturbed from the sine wave. In this research, the disturbance of acceleration wave was defined as degree of disturbance WD, the relation between compacting time, hearing capacity of ground, consistency of concrete, compaction degree of concrete, strength of concrete and...
