LIGHTLY TRAFFICKED ROADS-POLAND

IN THE FIELD OF UTILIZATION OF NON-TRADITIONAL LOCAL MATERIALS FOR ROAD CONSTRUCTION, PROGRESS IS BEING MADE IN POLAND IN THE USE OF LIGNITE FLY ASH REPLACING CEMENT AND LIME. MIXTURES OF FLY ASH OF LIGNITE AND COAL ARE GIVING GOOD RESULTS. MANY WASTE PRODUCTS ARE BEING USED AS FILLERS FOR COATED MATERIALS, INCLUDING REFINED RESIN POWDERS, FLOTATION POWDERS, AND CEMENT DUST HELD BY ELECTRO-FILTERS. CHALK IS ALSO BEING USED AS A FILLER. THE BEHAVIOR OF CARRIAGEWAYS IS APPRECIATED VISUALLY BUT DOUBTFUL SECTIONS ARE CHECKED BY AXLE-WEIGHTS AND SPECIAL NOTING OF HEAVY LORRIES. THE PROBLEM OF FIGHTING EROSION IS DEALT WITH ON THE BASIS OF RESEARCH CARRIED OUT ON DISTRICT ROADS. THE EROSION OF EMBANKMENT SLOPES CREATES THE GREATEST DIFFICULTY. THE FAILURE OF THE COVERING LAYER IS THE MAIN CAUSE OF DAMAGE. FINE AND SMOOTH SANDS ARE SOILS MOST SUSCEPTIBLE TO EROSION. THE MOST EFFECTIVE METHOD IS THE PROTECTION OF EMBANKMENT SLOPES BY MEANS OF BITUMINOUS IMPREGNATION. AS REGARDS THE INFLUENCE OF SECONDARY ROADS ON SOCIAL AND ECONOMIC DEVELOPMENT, AN EXAMPLE IS DESCRIBED OF DISTRICT DEVELOPMENT WHICH HAS CONSIDERABLY IMPROVED ITS ROAD NETWORK DURING THE LAST TEN YEARS. PARTICULARLY NOTICEABLE HAVE BEEN CULTURAL AND SOCIAL CHANGES IN VILLAGES WHICH HAVE BEEN LINKED BY ROADS TO TOWNS.
