Developments in Noise Redution of Concrete Roads in the Netherlands

Paper by EERLAND GROB ONSTENK from ISCR 6th 1990

In the Netherlands experiments have been performed recently :onceming noise reduction on concrete roads. Three pos-.ibilities are being investigated:I. Top layer of no-fines porous concrete.~. Surface of washed dense concrete.. Dense concrete with fine-grained epoxy surface treatment. noise emission level slightly higher than on porous asphalt,iut much less than on a "normal" concrete or dense asphaltoad, was achieved with porous concrete. Noise measurementsIn washed concrete gave results comparable to a noise emissionevel of dense asphaltic concrete, while on a fine-grained epoxy.urface treatment the noise level was as low as on porous as-ihalt,
