Place sharp or pointed objects on your driveway. Indentations will result. This will certainly be true for the first year of its life and perhaps longer (such as on a hot summer day when the mercury reaches 80°F or above). Stay off the new driveway 2-3 days after installation and longer if temperatures are hot.
Principal offenders are high heels, bicycle kickstands, ladders, porch chairs, etc.
REASON - The pounds per square inch on the above subjects is so great. This means that while small in area and light in weight, the weight involved is too great for the area concerned being all concentrated in one small spot. Also, asphalt is not a hard, tight material, but a soft, porous one.
