April 26, 2010 - Emerging high-speed inertial profilers can collect pavement profiles and, using computer technology, can simulate profilograph responses. ASTM International Committee E17 on Vehicle-Pavement Systems is developing proposed standard ASTM WK26262, Specification for Profilograph Simulation for Airfield Pavements, which will contain procedures for simulations based on current programs in use by U.S. Federal Aviation Administration and U.S. Federal Highway Administration.

W. CONSHOHOCKEN, Pa., -Since the appearance of the first California-type models around 1940, the profilograph has been a popular device used for quality control in the construction of pavements. Both roadway and airfield landing agencies have adopted roughness indexes computed from profilograph-derived measurements as a level of construction quality. Emerging high-speed inertial profilers can now quickly collect pavement profiles and, using computer technology, can simulate profilograph responses.

ASTM International Committee E17 on Vehicle-Pavement Systems is currently developing a proposed new standard for such simulation, ASTM WK26262, Specification for Profilograph Simulation for Airfield Pavements. The proposed standard is under the jurisdiction of Subcommittee E17.33 on Methodology for Analyzing Pavement Roughness.

According to Injun Song, research engineer, SRA International Inc., and an ASTM E17 member, ASTM WK26262 will contain procedures for simulations based on current programs already in use by the U.S. Federal Aviation Administration and the U.S. Federal Highway Administration.

"This proposed standard will provide a methodology to bring the basic philosophies of smoothness or rideability issues to an easier and more practical way to evaluate," says Song. "Any computer programmer or engineer who wants to add or create the simulation procedures in his or her program will be able to follow this standard to expect the same simulation results."

Song says that users who do not own a profilograph would be able to receive detailed information regarding wheel spacing and size and sample spacing from the simulations described in the proposed standard.

The proposed standard will be useful for: contractors collecting pavement surface profiles for both construction quality assurance and monitoring pavement conditions; agencies in airfield and/or highway pavement development under the U.S. Department of Transportation who want to simulate profilograph profiles using profiles from inertial profilers; and computer programmers or engineers who want to add or create the simulation function in their programs.

All interested parties are invited to participate in the development of WK26262. ASTM International welcomes and encourages participation in the development of its standards.

ASTM International is one of the largest international standards development and delivery systems in the world. ASTM International meets the World Trade Organization (WTO) principles for the development of international standards: coherence, consensus, development dimension, effectiveness, impartiality, openness, relevance and transparency. ASTM standards are accepted and used in research and development, product testing, quality systems and commercial transactions.
