Note the AWPA E25 test deck
design has since been modified on the basis of further experience with this test method.
These results correlate well with available NTPEP test deck retroreflectivity and durability ratings.
The relatively high cost associated with sample submission has resulted in only a limited number of test paints being placed on the test deck every year.
In addition, no flaming or glowing portion of the sample blown or falling off the test deck
can continue to glow after reaching the floor.
The last part of the test requires a sample that is a test deck
that can be anywhere from 8 ft.
Since transverse pavement markings were applied, all vehicles traveling in the marked lane drove over the test deck
, contributing to its wear.
The 4" hail passed through both test decks
. Testing then took place with the Vermont Slate on the same 3/8" wood deck, firing the 4" hail at 183mph, well beyond the typical terminal velocity of falling hail that size (approximately 100mph).
Approval of a new resin or marking material typically requires extensive evaluation on test decks
monitored by the National Transportations Product Evaluation Program (NTPEP), which is part of the American Association of State Highway and Transportation Officials (AASHTO), a nonprofit, nonpartisan association representing highway and transportation departments in the 50 states, the District of Columbia, and Puerto Rico.
Kasprowicz knows the Australian Test decks
better that most and believes there will be no issue for the young Glam star on that score.
Meticulously absorbed in every aspect of his work including the proper selection of finishes and fasteners, Rayboy has also experimented extensively on his very own test decks
to perfect his art.
Treated timber and batches of untreated and water-treated controls were then used in the manufacture of 4 test decks
, each deck containing 3 replicate boards for each treatment (12 boards in total).
