Are you looking for efficient and non-destructive methods for asphalt quality assurance? The Density Profiling System (DPS) offers real-time, continuous density measurements that enhance pavement performance and construction outcomes. TRB will host a webinar on Thursday, December 18, 2025, from 1:00 PM to 2:30 PM Eastern that will explore the application and advantages of DPS technology for continuous, non-destructive asphalt pavement density measurement. Presenters will share agency perspectives and case studies from recent field implementations, highlighting how DPS improves quality assurance, supports data-driven decision-making, and contributes to long-term pavement performance.
The registration fee is $100. Purchase a webinar package for discounted pricing. Complimentary registration is available for employees of TRB sponsors, standing technical committee chairs, involved CRP panel members, media, congressional staff, and TRB or National Academies staff.
