RT Journal Article SR Electronic A1 Lelak, Jan A1 Slavik, Dusan A1 Mecar, Martin T1 Static and Dynamic Tests of the Railway Subgrade Construction Model JF Communications - Scientific Letters of the University of Zilina YR 2004 VO 6 IS 1 SP 64 OP 67 DO 10.26552/com.C.2004.1.64-67 UL https://komunikacie.uniza.sk/artkey/csl-200401-0014.php AB The presented paper deals with the research of railway subgrade construction. The purpose was to compare static and dynamic modulus of deformation namely on two different railway subgrade constructions. The effect of reinforcing geosynthetics was found out as well, when a different type of reinforcing geosynthetics was used.
