Those are indeed concrete paving bricks. They're more expensive to install, but I think cheaper to maintain. For example, if there's a problem beneath them (leaky pipe etc), you can pull up the paving bricks, fix the problem, and replace the paving bricks -- you don't have to pay to re-lay a substantial portion of the surface like you would with asphalt.

I work in HKG and no one can tell me why using concrete bricks for the apron. My guess is that it is for the ease of maintenance as Brenintw has pointed out, and also for the flexibility to add stuffs like pipes and cables running under the apron.
Here is a pic showing when the A380 visit HKG last saturday, they actually had to run extra power supply to the aircraft. The temporay power supply is the little tower underneath the airbridge, conned off, then run two yellow cables to the nose gear, along with the existing orange ones from the airbridge. The temp power supply tower was put there in one night, I guess the apron being built with concrete bricks helped.

Many stands at LHR, all the T1 Domestics for example are laid with brick pavers. They are excellent when maintainance is required as they are taken up and relaid very quickly with minimum stand closure time. No cement...no drying time.....
