| 摘要： | This report presents a set of recommended test methods for evaluating durability of detectable warning systems. These methods address exposure regimes, test procedures, and evaluation criteria to help select detectable warning systems that provide long-term performance and durability while meeting the requirements of the Americans with Disabilities Act Accessibility Guidelines (ADAAG). The test methods are presented in AASHTO format to facilitate consideration and incorporation into the AASHTO Standard Specifications for Transportation Materials and Methods of Sampling and Testing. The material contained in the report should be of immediate interest to state materials engineers and those concerned with the different aspects of the ADAAG. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
