FABRIC MEMBRANE IN FLEXIBLE PAVEMENT CONSTRUCTION OVER SOILS OF LOW BEARING STRENGTH

THE ARTICLE DESCRIBES THE PERFORMANCE OF A NON-WOVEN FABRIC KNOWN AS PRF140 DEVELOPED BY ICI FIBRES, AND DESIGNED AS A SEPARATION MEMBRANE BETWEEN SUBGRADE AND SUB-BASE OF TEMPORARY ACCESS ROADS BUILT ON LOW-BEARING-CAPACITY SOILS. THE FABRIC IS COMPOSED OF TWO TYPES OF CONTINUOUS FILAMENT; ONE TYPE IS POLYPROPYLENE, THE OTHER A HETEROFILAMENT COMPRISING A POLYPROPYLENE CORE WITH A NYLON SHEATH. TESTS DESCRIBED AT A NUMBER OF SITES SHOW THE FABRIC TO BE OF USE AS A SEPARATOR TO PREVENT HARDCORE FROM SINKING INTO A SOFT SUBGRADE SOIL. /TRRL/
