โœฆ Synopsis

We extend our earlier work on developing a low-noise pavement by considering a porous elastic road surface (PERS). We find that the noise characteristics of PERS are superior to those of a drainage asphalt pavement including the normal absorption coeficient. We have found signtficant total noise (power unit plus tire/road noise) reduction of PERS for both cars and trucks, 13 and 6 dB(A) respectively. In addition, in this paper, we present a new technique of processing the noise for short intervals.

## In this report, we analyze the relationship between noise reduction and the thickness and aggregate size of the drainage asphalt road surface. Earlier results indicated overall noise reductions of 3-5 dB. However, noise reductions of 5-10 dB are necessary to improve the urban roadride areas of Ja

The measurement of dynamic surface tensions by a differential maximum bubble pressure method has been used to permit the determination of Marangoni surface elasticities associated with the interface between gas and foam-forming surfactant solutions. The method was used to study the behaviour of a nu
