Continuously Reinforced Concrete with Noise Reducing Surface for the Reconstruction of the E31 3 (Al 3) Motorway in Hasselt (Belgium)

Paper by POELMANS HENDRIKX BOGAERTS from ISCR 7th 1994 Vienna Austria

rFor the reconstruction of the E31 3 motorway which was constructed with concrete slabs round about 1960, CRCP was chosen and since 1983 the exposed aggregate technique was applied there. As the conventional exposed aggregate concrete is still too noisy, in 1992 it was decided to pursue the reconstruction works by adapting the paving texture on a 1.8 km long test section near Hasselt, by limiting the aggregate size to 20 mm and by imposing a "super-smoother"
