Laid Asphalt quality has a lot of variables to it so it's really hard to compare the results unless everything is done to a specified standard.
The driveways and small jobs will have many a deviation from what would be considered standard on a properly supervised Government road paving job.
Variables:
First and foremost is the sub grade, material type, depth, standard of compaction, drainage and even finished smoothness.
Type of asphalt used, type and grading of the crushed gravel used, The actually mixing plant design, size and operator skill, Job site delivery temperatures, Type of compaction equipment used and the compaction method, Degree to which it is compacted, the thickness of the mat, the outside temperature and weather and lots of items I neither know or have forgotten.
Also one must realize the small job lots may use a blend of asphalts on hand, aggragate that does not meet the specs that major users will demand and perhaps lower temperatures and less mixing at the plant.
Makes it hard to compare jobs.:thumbsup:
