Concrete Driveway

Many driveways  that were going to have texture sprayed on have  many random cracks. (hairline --1/2 " wide). I would like to know the best way of patching these cracks. to minimize reoccurrence  through texture. Thank you very much
I would need more information.
Are these concrete driveways? What distance between cracks?  When did the cracks appear? Do the cracks keep growing or are they stable?
What type of texture coat are you talking about?
Where are you? What is the weather like?  Is it freezing? large temperature differences?
How is the soil? Expansive?
Whatever you know will help.

NO FURTHER RESPONSE FROM THIS PERSON...
I don't if this is something that is in your area of work, but if it is not maybe you could direct me to someone who can help.
We have a driveway at our home in Lake Arrowhead that is about 6 years old, approx. 25' x 35' and is sloped. The driveway has developed many cracks. I am wondering if the driveway was built to code, there are no expansion joints.
From your description this is a very simple case of not following the rules (and codes).
ACI (American Concrete Institute) recommends joints at 10-15' max. (depending on thickness and strength of concrete).  If you do not do that, you can expect cracks where the joints should have been (and some extra).
If the concrete was not cured and protected correctly during the first week, it could explain some additional cracking.
