The behaviour of plain concrete slabs, belonging to pavements with no dowels through transversal Jo~nts, is described. The slab behaviour is observed by means of field instrumentation, measuring absolute deflections produced by environment variations (temperature and moisture), by support rigidity variations and by a controled axle load. Deformations are measured...

Erosion of concrete pavement sub-bases
A special session of the 65th annual meeting of the Transportation Research Board in Washington, in January 1986, brought together some 50 practitioners and research workers on the theme "Erosion of sub-bases; stepping of slabs and pumping of concrete pavements"; ~he presentation of 3 U.S. papers and two French ones...
Road concrete with superplasticizers
Road concrete made with superplasticizers has successfully been used for about ten years now. Its special features with regard to mix composition and method of placing were reported in detail at the London symposium in 1982. This method of construction is increasingly being applied in Austria: - For the maintenance...
Maintenance and Rehabilitation of Concrete Roads
For the repair of concrete roads to be effective and economic it is essential to have planned maintenance procedure. Details of such a procedure are to be published in the forthcoming publication "Manual for the Maintenance and Repair of Concrete Roads" ,which is to be adopted for roads administered by...
