Coughing up thick mucus and chesty cough for over three weeks....Is this normal? - thicker mucus than normal

I'm an asthmatic, so, but has no effect on normal respiration. It is a thick, green, and occurs when a bad cough for about five minutes. Its always extremely annoying, but I wonder, is it normal, like the cough of three weeks. I'm not coughing all day, but the cough for about 10-12 times a day and always, whenever there is a large amount of thick mucus. I want to meet only decent please.
