ASTM Int'l Proposed Standard Measures Adhesion of Coatings to Driveways - ASTM WK14355

December 16, 2007 // Published as a news service by IHS

ASTM WK14355 - Practice for Evaluating Hot Tire Pick-Up of Coatings Applied to Concrete is used to evaluate the durability and adhesion of paints applied to concrete driveways that were heated and then subjected to a compressive force with a rubber tire to simulate the effect of a car sitting on an exposed coated driveway that was heated by exposure to the sun.

"This proposed practice could be used to test any coating for adhesion and/or tire marking on concrete driveways or garage floors," said Richard Potter, senior formulator, United Gilsonate Laboratories.

"The most likely users of [ASTM] WK14355 would be coating manufacturers that make coatings for driveways or garage floors and suppliers and manufacturers of raw materials that are sold or being evaluated to be sold to coatings manufacturers for end use."

"We know that there are a wide variety of testing practices being used in various laboratories around the world," said Potter, who also said that it is a long-term goal of the subcommittee to have uniform testing methods that can be reproduced by anyone who wants to perform tests.

"For [ASTM] WK14355, we would like to have input from anyone who has been using a proprietary procedure that could have input in improving it," said Potter. "It is very difficult to exactly reproduce what happens in the real world with accelerated lab testing so we would appreciate any input that could help this practice achieve this goal."

The proposed practice is being developed by Subcommittee D01.47 on Concrete, Stone and Masonry Treatments, which is part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
