The Mediterranean Highway has been in service for more than fifteen years, and we can state that the performance of the concrete paving has been overall excellent whether referring to its surface characteristics or its structural characteristics, except for those areas giving support where damage has taken place. The modifications...
Evaluation and Maintenance of the Concrete Pavements on the Mediterranean Highway
Load Transfer Restoration LCPC Freyssinet Connector
The LCPCIFREYSSINET slab connector is an innovating device allowing load transfer restauration of concrete roads submitted to pumping effects. It is constittïed by two synietrical half-shells in cast iron glued to a central elastomeric pad and contains an adjusted steel-pin which slides freely within housings machined in the shells, making...
Proposed Test Method For a Procedure to Stitch Longitudinal Weakened Plane Joints in a Plain Jointed Portland Cement Concrete Pavement Where Tie Bars Were Ineffectivel Y Located During Construction
The method used to conduct pull-out tests on tie bars cast into the edge of an existing concrete pavement is described. The test results are used in conjunction with a simple statical procedure to design an economical system for stitching sections of longitudinal weakened plane joints in a plain jointed...
Very Thin Surfacings For Improving Skid Resistance of Concrete Pavements
This paper describes work on the skid resistance properties of some fine aggregates available in Indiana, as an attempt to improve the driving safety characteristics of concrete pavements. In this work the British Polishing Machine and the Portable Skid-Resistance Tester were used for laboratory evaluation of some mortar mixes. Aggregates...
Pavement Rehabilitation. Tools That Work
A nation's highway system is an investment used to transport manufactured goods and farm products. The challenge in maintaining this transportation system has been devising a cost-effective rehabilitation method as an alternate to the «bandaid » cover up. This paper describes the six steps of concrete pavement restoration plus two...
The Design and Maintenance of Contraction Joints Behaviour of the Namur Test Road After 10 Years of Traffic
This article describes the behaviour after 10 years of service of the test sections constructed in 1979 on State road N 4 in the Belgian province of Namur, The object of this experiment, is to compare various types of contraction joint on the same site and under the same conditions...
Rapid Rehabilitation Techniques with Cement Concrete_ Applied on Deformed Asphaltic Roads
On asphaltic roads the so called «wash-boardeffect » in front of traffic lights is a well known phenomenon. Regular reconstruction of these areas places a significant and recurrent burden on road managing authorities. Because of the large volumen of traffic at these intersections repair works also lead to a huge...

Surface treatment of limestone concrete slab with the chipping technique
Since 1980 the technique of pavement construction with thick concrete slabs has been applied on 100 km of the A.26 motorway (Calais - Reims) in northern France. The concrete employed is made with regional limestone aggregates. In order to counteract lowered skidding resistance due to wear of these materials, a...
Continuous quality control of high performance concretes for road – within the framework of site supervision – using a new field tested BASIC-MC programme
Introduction and statement 'of problems: This paper closes the gap in concrete highway engineering technology by evaluating complex compactionphenomena and by deriving mathematical relationships between the concrete-technological, dynamic (thixotropic- plasticized) and physical parameters. It is based on the latest experience, e.g., including the construction of the concrete pavements of the...
