perhaps your engine trim is too high causing excess speed on approach. the thing to remember is steer with rudder and ailerons until speed is low enough to give it full up elevator so the tail stays down while taxing.
also a couple of "clicks" of throttle on approach then cut to idle as you cross the runway threshold would help.
i normally fly on grass and have flown on asphalt. ashpalt is much faster. you can put a cardboard spacer on your main wheels to slow them down while on asphalt, however if you land in grass it will act as a brake so dont forget to take them off if you go to grass.
the best thing to do is join a local club and use their field. you get advice from members, and will have good company to "hangar fly" with.
good luck and keep the shiney side to the sun lol
