Comparing Bournemouth to MAN is comparing apples and oranges. One is a rambling old site with acres of old taxiways and a tiny operation at the best of times, the other is a very large multi billion site with a worldwide operation that has slowed but will begin to pick up rapidly in the next couple of months.
If you loose a single runway for whatever reason thats it, game over, if you have the luxury of a second runway that can be re opened rapidly that is a major attraction to airlines. Runway 2 at MAN is predominantly of asphalt construction it has a PCN sufficient for all aircraft types, however its very expensive runway surface could be susceptible to asphalt degradation should any fuel or oils leak onto the surface from a stored airliner, that then could becomes an expensive repair bill. The asphalt used on a runway is part of a finely engineered surface that has to cope with the weight, exhaust temperature and thrust of aircraft and provide friction characteristics that allow safe braking and steering at high speed, thats why aprons are usually made of tough thick Concrete that can withstand prolonged weights and leaky old Virgin 747s !
