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...
Effectiveness of Load Transfer in Jointed Reinforced Concrete Pavement
The load tiansfer due to the dowel bars in jointed reinforced concrete pavements (JRCP) or to the steel reinforcing in continuously reinforced concrete pavements (CRCP) has also the effect of reducing the stress on the edge of the load slab. Therefore, the calculation of the load transfer between contiguous slabs...
Effects of Loss of Support on the Residual Life of JPCCP
One of the most frequent ajid insidious distresses in Jointed Portland Cement Concrete Pavements (JPCCP) is the loss of pavement support near the joint. This problem is principally caused by a lack of maintenance ofjoint sealing that can give rise to the well-known phenomenon called pumping in the presence of...
Longtime Experience with Exposed Aggregate Surfaces in Austria
Exposed aggregate surfaces MA 8 have been used in Austria on a !arge scale since 1990 and have proveu not only noise-reducing but also very skid resistant. On different motorway sections paved with the same quarzitic chippings 4/8 the friction values (Stuttgart friction meter, 60 km/h, with water, with slip)...
