Die Erhaltungsprojekte N6, Rubigen-Thun-Spiez (RUTS) haben\u00a0daher zum Ziel, die Fahrbahn \u00fcber die ganze Strecke zu sanieren\u00a0und dabei den neuesten Standards anzupassen. Damit verbunden\u00a0sind die Instandsetzungen und Anpassungen der Kunst- und St\u00fctzbauwerke\u00a0sowie Neubauten.<\/p>\n<p>Aufgrund einer Verschiebung der Bauetappen wird das Teilst\u00fcck\u00a0zwischen Kiesen und Thun Nord (TP-3 Heimberg) fr\u00fchestens\u00a0im Jahr 2019 instand gesetzt. Da der betriebliche Zustand der\u00a0bestehenden Betonfahrbahnplatten jedoch bis dahin ungen\u00fcgend\u00a0ist, waren \u00dcberbr\u00fcckungsmassnahmen notwendig. Diese\u00a0beinhalteten die tempor\u00e4re Stabilisierung der schlecht gelagerten\u00a0Betonplatten mittels Kunstharz-Injektionen durch die Firma\u00a0URETEK Schweiz AG.<\/p>\n<h2>Kunstharz stabilisiert die Platten<\/h2>\n<p>Die Fahrbahnplatten sind aus Beton und ungef\u00e4hr 22 cm stark.\u00a0Unter den Betonplatten gibt es eine Kofferung von ungef\u00e4hr\u00a050 cm. Im erw\u00e4hnten Autobahnabschnitt sind einige Fahrbahnplatten\u00a0im Fugenbereich instabil geworden. Die Instabilit\u00e4t der\u00a0Platten f\u00fchrte vor allem bei der \u00dcberfahrt von Schwerverkehr zu\u00a0Schwankungen, vereinzelt sind auch Stufenbildungen entstanden.\u00a0Das URETEK-Fachpersonal leitete und f\u00fchrte die Arbeiten mit\u00a0einem mit der gesamten Arbeitsinstallation ausger\u00fcsteten Lastwagen\u00a0durch.<\/p>\n<p>Das URETEK Floor Lift<sup>\u00ae<\/sup>-Verfahren l\u00e4sst sich generell wie folgt\u00a0beschreiben: Das URETEK-Kunstharz wird fl\u00fcssig und mit kontrolliertem\u00a0Druck durch Bohrl\u00f6cher von 12 mm und in einem horizontalen\u00a0Abstand von ca. 1,0 m direkt unter den Betonbodenplatten\u00a0injiziert. Es verteilt sich, f\u00fcllt alle Hohlr\u00e4ume und verdichtet\u00a0und verfestigt den Untergrund durch die Expansionskraft einer\u00a020-fachen Volumenvergr\u00f6sserung (im Luftraum gemessen). Der\u00a0ganze Vorgang der Stabilisierung wird durch ein Laser-Messger\u00e4t\u00a0kontrolliert.<\/p>\n<h4>Die Arbeitsleistung ist in der \u00dcbersicht beschrieben:<\/h4>\n<table class=\" aligncenter\" style=\"width: 100%; margin-bottom: 40px;\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td style=\"background-color: #f2f2f2; text-align: center;\" rowspan=\"2\"><span style=\"color: #ef7d00;\">Fahrbahn<\/span><\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\" rowspan=\"2\"><span style=\"color: #ef7d00;\">Zeitraum<\/span><\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\" rowspan=\"2\"><span style=\"color: #ef7d00;\">Anzahl Platten<\/span><\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\" rowspan=\"2\"><span style=\"color: #ef7d00;\">Fl\u00e4che<\/span><\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\" colspan=\"4\"><span style=\"color: #ef7d00;\">Menge Kunstharz<\/span><\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #f2f2f2; text-align: center;\"><span style=\"color: #ef7d00;\">gesamt<\/span><\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\"><span style=\"color: #ef7d00;\">\u00a0min.<\/span><\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\"><span style=\"color: #ef7d00;\">\u00f8<\/span><\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\"><span style=\"color: #ef7d00;\">max.<\/span><\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #e9e9e9; text-align: center;\"><\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\"><\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\"><\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">[m<sup>2<\/sup>]<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">[kg]<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">\u00a0[kg\/m<sup>2<\/sup>]<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\"><\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\"><\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #f2f2f2; text-align: center;\">Richtung Thun<\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\">08.\u201324.06.2015<\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\">395<\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\">3950<\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\">9099<\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\">\u00a01.7<\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\">\u00a02.3<\/td>\n<td style=\"background-color: #f2f2f2; text-align: center;\">\u00a03.3<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #e9e9e9; text-align: center;\">Richtung Bern<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">25. &amp; 29.06.2015<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">85<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">850<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">2144<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">\u00a01.9<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">\u00a02.5<\/td>\n<td style=\"background-color: #e9e9e9; text-align: center;\">\u00a03.2<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Die Kunstharzinjektionen auf der N6 fanden im Zeitraum vom\u00a008.bis 29.6.2015 statt.
