TRANSVERSE GROOVING TESTS ON CONCRETE PAVEMENTS

ESSAIS DE STRIAGE TRANSVERSAL DES CHAUSSEES EN BETON DE CIMENT

The skidding resistance of carriagewyas, on which vehicles travel at high speed, depends on the possibility of breaking up and eliminating the film of water between the carriageway and vehicle tyres. The surface treatment of concrete pavements was studied at the CRR (Centre de Recherches Routieres) in Brussels, which has developed a machine which operates on conventional form work and which can automatically produce deep transverse grooves on fresh concrete. The tests described in this article had the following aim: (1) to control the grooving property of concrete the mix-design of which had been selected for slip-form application, (2) to investigate the influence of surface finishing procedures on the quality of the grooves, (3) to check the possibility of transversely sawing at a skew angle at a 1/6 slope a grooved carriageway without causing spalling when the shrinkage joints are sawn, (4) to determine the wear of grooves made in a concrete containing 330 KG cement per M3 under the influence of traffic, (5) to study the noise level of moving vehicles, (6) to examine problems of application. Tests were carried out on a road on which approximately 4000 vehicles travelled per day, 25% of them being heavy vehicles. The depth of the surface treatment and the coefficient of longitudinal friction were measured before the road was opened to traffic and a year later.
