PAVEMENT STRUCTURE - POLAND

THERE HAS BEEN INTEREST IN POLAND FOR QUITE A TIME ON THE CAUSE OF CRACKING OF BASE LAYERS STABILIZED WITH CEMENT. ON THE BASIS OF TESTS AND OBSERVATIONS IT HAS BEEN NOTED THAT: /1/ THE CRACKING OF LAYERS IS MOST OFTEN CAUSED BY THE LACK OF UNIFORMITY OF THE COMPACTION OF THE SOIL UNDER HIGHWAY TRAFFIC. IT IS A KNOWN FACT, THAT VEHICLES NORMALLY TRAVEL ON THE SAME PATHS, WHICH IS DOUBTLESS THE PRINCIPAL CAUSE OF THIS TYPE OF CRACKING. IT IS NOTED THAT THE IRREGULAR PATTERN OF CRACKS OFTEN APPEARS IN THE PLACES WHICH ARE EXPOSED TO THE NUMEROUS JOURNEYS PERPENDICULAR TO THE AXIS OF THE HIGHWAY, /2/ TO ANTICIPATE FORMATION OF CRACKING IN BASE LAYERS IN SOIL CEMENT, IT IS THEREFORE ESSENTIAL TO PAY SPECIAL ATTENTION TO THE COMPACTION OF SOIL CEMENT DURING THE CONSTRUCTION OF THE HIGHWAY AND ALSO THE SUBGRADE SOIL ITSELF. IT IS ALSO NECESSARY, THAT THE MIXING WITH CEMENT IS IN SUFFICIENT DEPTH, AND /3/ CRACKING DOES NOT BRING ABOUT VERY SERIOUS DAMAGE, BUT IT REQUIRES SUPPLEMENTARY PRESERVATION WORKS SUCH AS THE CLOSING OF THESE CRACKS WITH SEALANT MATERIALS.
