Ashhalt Millings Driveway Bumpy Chunks

My dad had millings for his driveway a while back and they turned out great....almost like black top. I'm not sure if they were fine or chunky b/c I wasn't around when he did it. I had 4 loads of millings delivered for my driveway and its ruff and bumpy. There were chunks and the driveway is pretty bad. it was spread with a bobcat and then rolled with a small rider roller. Anyway I can smooth this out? Bigger roller? I think its the chunks that messed everything up and i'm disappointed as the driveway is in bad shape.

thanks
