Microstructure of porous pavements - Experimental procedures

摘要: The DRI-DWW Noise Abatement Programme is a joint cooperation between the Road and Hydraulic Engineer-ing Institute (DWW) in Netherlands Danish (DRI) for research development issues related to abatement of road traffic noise.The present report addresses two techniques analysis assessment drilling cores from sections with porous asphalt.The addressed are CT-scanning asphalt drill thin plane prepared scanned analysed microscope.The has proven give information about microstructure that could not be identified other know techniques.The only presents prepared, no relations performance po-rous pavements on roads studied.Hence, it should noted this phenomenological study cores.
