Improved Life for Longitudinal Joints in Asphalt Pavement - WisDOT ...

Quality ControlThe following research focuses on the use of field permeameters for quality-control monitoring of longitudinaljoints.New England Transportation ConsortiumProject 03-5, Evaluation of a Field Permeameter as a Longitudinal Joint Quality Indicator, Jo Sias Daniel, RajibMallick and Walaa Mogawer, University of New Hampshire, April 2007.http://www.netc.umassd.edu/netc03_5_final_report.pdfThis study sought to evaluate the use of field permeameters for evaluating the quality of constructed longitudinaljoints. Various construction methods were used, including the use of infrared heaters and joint sealants. Based ondensity, air void content and strength from cores, conclusions included:• Permeameter use is promising but requires refinement to reduce variability.• Joint sealants and joint heaters improve short-term joint performance.See also “Development and Evaluation of a Field Permeameter as a Longitudinal Joint Quality Indicator,” R.B.Mallick and J.
