Typical Collection Method ASTM D6433-99

Samples - The lowest order of the definedpavement network. All samples mustbelong to a network, branch and section. Allpavement sections will be divided into 300foot pieces, with the sample portion takenfrom the beginning of each 300 foot piece.The length of the sample area will dependon the width of the roadway. Transmaplooks at the total width of the roadway onnon-divided average roads. In general, thegoal is to have sample areas between1,500 sq. ft and 3,500 sq. ft.

Why Sample?

• Scott McDonald (Certified MicroPAVER Trainer) says tothink of the pavement analysis like a bell curve.

• Real information is inside the sweet spot.• If you measure too little, the appropriate amount of

information is not getting attributed to the segment.o This will skew your PCI to be higher.

• If you measure too much, you're wasting your time (SameResults).

• Measuring at a specific interval (middle range).
