National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Pavement and Geometric Design Criteria for Minimizing Hydroplaning. A Technical Summary.

PB80190457

Publication Date	1979
Personal Author	Gallaway, B. M.; Hayes, G. G.; Ivey, D. L.; Ledbetter, W. B.; Olson, R. M.
Page Count	112
Abstract	The authors have covered the empirical indications of hydroplaning as determined from hard data. Precise measurements of surface drainage were examined, and equations relating pavement texture and cross slope and rainfall intensity were developed. Vehicle control as related to variation in cross slope was simulated with the HVOSM simulation model. A determination of the deficiencies in existing surface drainage design methodology for sag vertical curves was conducted, and innovative solutions to these problems are presented. From a detailed study of state rainfall records a method is presented for determining a design rainfall intensity. Field studies of open-graded friction courses included water depths in simulated and natural rainfall, the effects of tire type, tread depth, inflation pressure, vehicle speed and accumulated traffic.
