<p>SLAB INTELLIGENT TRACk VERSATILE IVES AND SOLID EffICIENT</p> <p>RHOMBERG RAIL</p> <p>IVES SYNTHESIS Of DESIGN AND CONSTRUCTION EXPERIENCERhomberg Rail can call on years of theoretical and practical know-how in the various types of slab track construction. And the result is IVES, the latest development in ballastless track construction. IVES stands for intelligent, versatile, efficient, solid. All these characteristics are embodied in this integrated concept, which is based on an analysis of the advantages and disadvantages of various long-term tested slab track techniques.</p> <p>PHILOSOPHY AND CONSTRUCTIONDuringthedevelopmentofIVES,thevariouspossiblecomponents,materialsandworkingprocesseswereinvestigatedand matchedtooneanothertocreateanoverallsystemthatworks wellandiscost-efficient.Theresultisatechnicallyandeconomicallyoptimisedformofconstructionthatreducesnotonlycostsin ordinaryfieldsofapplicationofslabtrack(high-speedtrackinhighly developedregions)butalsoallowsaconsiderablywiderrangeof usesofthistechnologyasanalternativetoballastroadbed.</p> <p>Load capacity</p> <p>Accuracy</p> <p>Overall qualityThe requirements for overall quality are consistently fullled.</p> <p>The load capacity The inuence of requirement decreases manufacturing The amount as the stresses from accuracy on vehicle of work involved in the railway loads track guidance building the track decreases decrease from decreases from the bottom upwards. the top from top Amount of work downwards. downwards.</p> <p>The IVES efficiency principle:</p> <p>Loadcapacity,accuracyandamountofworkareideallymatchedtotherespectiverequirements.Intermsofcostandeffort, IVESinvolvesasmuchasnecessaryandaslittleaspossibleoftheseresourcesinallareasofconstruction.</p> <p>BasicprinciplesofIVES</p> <p>EffICIENT USE Of COMPONENTS AND MATERIALSOneofthekeyideasinthedevelopmentofIVESwastheefficientanddeliberateuseofcomponentsandmaterialswithqualitiesthat matchtheirrespectiverequirements.Likewise,manufacturingmethodsandtransportandconstructionprocessestakeintoaccountthe objectiveofincreasingefficiency.Theresultsareconstituentpartsthatarequickandeasytoproduce,transport,handleandinstall.</p> <p>RAIL fASTENING SYSTEM TheDFF304systemisbasedonprovenandapprovedcomponents.Thesupportpointsweremodifiedsothattheyprovide aformofdirectfastening(groutedintotheprecastelement)to fulfilthehighestdemandsforlong-termpull-outresistanceand convenienceofinstallation.</p> <p>RailfasteningDFF304</p> <p>STRUCTURAL ELEMENTS Thesecomponentscarrythegrouted-inrailfasteningsand transferthevehicleloadintothebaselayer.Astheydonot directlydeterminetherailgeometry,theycanbemanufacturedintheappropriatequalitywithoutadoptingtoohigha technicalstandardsothatcostscanbekeptrelativelylow.</p> <p>Structuralelement</p> <p>GROUTING IN THE RAIL fASTENINGS Ahigh-strength,rapid-hardeninggroutingmortarisusedso thatgroutingtherailfasteningsintotheprecastconcreteunits isaneasy,quickandreliableon-siteprocessthatachievesa high-qualityresult.</p> <p>BASE LAYER Thebaselayerispreferablyconstructedofroadasphaltusingconventionalmethods.Asarule,thebaselayershould havedowelsinsertedtocreateaconnectioncapableof transferringshearfromthestructuralelementsintothe baselayer.</p> <p>INSTALLATION TECHNIqUE: SIMPLE, RELIABLE, qUICk, fLEXIBLETHE SUCCESS Of THE IVES INSTALLATION CONCEPT IS BASED ON THE fOLLOWING: Combination of bottom-up and top-down installation principles Efficient distribution of the accuracy and amount of work involved Efficient use of material and component qualities Appropriate simplification of components</p> <p>INSTALLATION SEqUENCECONSTRUCTION Of BASE LAYER Thebaselayer,preferablyconsistingofasphalt,isnormally laidwitharoadfinisherinaccordancewiththebottom-up principle.Theaccuracyrequirementsarelowerthanmost roadconstructionprojectsandshouldbequiteeasyto achieve.
