Method for the assessment of air pore structure on the airfield pavement

摘要

the pore structure solves issue of aircraft in the airport cement concrete pavement, and its main use is forecasting its durability. the sample shall be proven by drilling well drilling rig pistoletowej, each hole is placed in the holder on the table handling computerized ct scan.then using x-ray ct scan lamp computer drilling examines out a x-ray permeating material samples, obtaining a three-dimensional image of high resolution structures and three-dimensional image of selected planes y perpendicular to the longitudinal axis of the image and their records in electronic form in computer memory.using a computer equipped with software for the distribution and count up the number of pores in different size classes are analysed two-dimensional images of planes.
