RouteParams it's not available in the root component. It's only available to the routable components.

See RouterOutlet soure code, in its activate function, you can see the following

var providers = Injector.resolve([
  provide(RouteData, {useValue: nextInstruction.routeData}),
  provide(RouteParams, {useValue: new RouteParams(nextInstruction.params)}),
  provide(routerMod.Router, {useValue: childRouter})
]);

Basically RouteParams is being injected through RouterOutlet to the routable components, you can't access it in non-routable components (sorry for repeating myself).
