My husband & I are trying to determine what type of driveway to install in our new home. He'd like the more traditional blacktop and I say some sort of concrete design? He doesn't want concrete b/c he say's it will crack. Our gargage is concrete and there are cracks all over. How can I be sure or is there something special to use that we won't get cracks in a driveway.

There really is no way to prevent cracks or predict accurately where or when they will occur. Some cracks appear almost immediately as the concrete cures. Some will present themselves months or years later. Some are weather dependent. Some occur as the earth moves.

What can be done is to have a designed concrete mix for your area, and a designed plan of pours and jointing for the driveway slab(s). You might need a professional engineer to prepare the plan. The plan would indicate how the driveway would be divided into pours that limit the amount of expansion and shrinkage the slab will experience as it cures. It will show where construction, control, and tooled joints should be placed to "catch" cracks that might occur. Construction joints occur between concrete pours. Control and tooled joints are installed after a concrete pour is done, while the concrete is setting up, but before it hardens. These joints basically provide a weak vertical plane in the slab where a crack will occur if it's going to occur. A crack occuring at a control or tooled joint will most often not be apparent. Having the concrete mix designed for your area can most often be accomplished by the ready mix company. In some areas, and in some companies, what is called "admixtures" are added to the concrete mix to vary the strength characteristics of the concrete. They can be chemical or small fibers made of various materials.
