I don't think there is much you can do to extend the tree's life; with 
the exception that if it's about to split you could have an arborist 
wire it up. Any other work to fill the holes won't "save" it but might 
make it look better to you. However the way it is now, it's a home and 
food source for wildlife. One reason that it's probably dying is that 
blacktop around it - which has killed the surface roots- assuming the 
tree was there first.

In the forest, many maples are hollow and live for centuries.
