Statistical Pass-By (SPB) method

Areas of Expertise (1)

|

The purpose of this method is to determine the acoustic quality of a given road pavement at a well-defined location. BRRC performs this test according to the specifications given in the relevant standard ISO 11819-1. A sound level meter and a tachometer are installed on the roadside to measure the maximum sound pressure level and the speed of a large number of randomly sampled passing vehicles. The results are statistically processed into an SPB index (SPBI), which is a good measure of the acoustic quality of the pavement at the measuring site – more particularly, of the influence of the pavement on traffic noise load for local residents. A full description of the test can be found in BRRC’s leaflet F67 “La méthode Statistical Pass-By (SPB)”.

Core Tasks (1)

>>

The objective of this three-year research project, in which thirteen partners were involved, was to develop techniques to treat steel slag (both LD and EAF) right from the production stage so as to give it good characteristics and volume stability. It was completed in the year 2000 and the final report has been released.

End of life strategies of asphalt pavements (Re-Road)

The main objective of this four-year European research project (from 1st January 2009 through 31st December 2012; fifteen partners) conducted under FP7 was to maximize the reuse of reclaimed asphalt (RA) in bituminous mixtures, with as little downscaling of the material and as little use of new material as possible.

Sectoral operator for E227 Road Materials

Ever since CEN/TC 227 Road Materials was formed in the late eighties, that is, before there were any plans to reorganize the standardization landscape in Belgium, BRRC has been a pioneer and an active participant in this committee. The main focus at the time was on the activities of WG1 Bituminous Mixtures and WG2 Surface Dressing, Sprays and Slurry Surfacing (incorporating Microsurfacing).
