Abstract

THIS DOCUMENT DEFINES THE NORMAL METHODS OF USING ANY TYPE OF SOIL IN EMBANKMENTS AND IMPROVED SUBGRADES. BY NORMAL CONDITIONS, IT IS MEANT CONDITIONS NECESSARY FOR OBTAINING AN EMBANKMENT OR IMPROVED SUBGRADE FULFILLING THE STANDARD QUALITY REQUIREMENTS, USING CONVENTIONAL METHODS OF EXECUTION OF THE WORK. IF THESE CONDITIONS ARE FULFILLED, IT IS POSSIBLE TO OBTAIN:- EMBANKMENTS WITH DEFORMATIONS NOT HARMFUL TO THE TRAFFICABILITY OF THE ROAD; AND IMPROVED SUBGRADES WITH THE REQUIRED BEARING CAPACITY AND SURFACE CONDITIONS. THE PROBLEMS WHICH CAN ARISE DURING THE EXTRACTION OF THE MATERIALS ARE NOT DEALT WITH; CONDITIONS RELATING TO THE EXTRACTION ARE MENTIONED ONLY WHEN THEY HAVE A DIRECT RELATION WITH THE QUALITY OF THE EMBANKMENTS BUILT. ATTENTION IS DRAWN TO THE FACT THAT THE PREVENTION OF SLOPE EROSION IS NOT STUDIED. FOR VOLUME1, SEE IRRD ABSTRACT NO. 104544, FOR VOLUME3, IRRD ABSTRACT NO. 104546.
