Cracks have formed in my driveway over the past couple of years. They are relatively thin - probably 0.5" at the widest point - but wide enough that weeds have taken root in them. There are essentially 3 separate cracks & their combined length has approximately doubled over the past 12 months. This picture shows the two largest cracks in focus, with the third (much smaller) crack in the background.
I live in a cold climate (New England) & I'm worried that ice will cause the cracks to expand. Is there a DIY fix I can use to prolong the life of the driveway / prevent these cracks from expanding?
