Paper by FRANKLIN JONES MERCER from ISCR 7th 1994 Vienna Austria
A full-scale trial has been constructed in the UK in which concrete surfaces with brushed, tined bnd exposed aggregate textures have been compared with traditional hot rolled asphalt. The concrete surfaces were applied to a 250 mm thick, continuously reinforced concrete pavement laid by railmounted paving equipment. The exposed aggregate surface gave the lowest noice level and the best tonal quality of all the types of surfaces, including the hot rolled asphalt. I he lower noice level ot the exposed aggregate was achieved whilst maintaining a satisfactory high-speed skidding performance compared to that of the hot ,olled dspIIdlL.
