National Asphalt Pavement Association (NAPA) webinar. Modern design tools such as PerRoad and PaveXpress, which now includes PerRoad design criteria, facilitates straightforward design and analysis of perpetual pavements. To promote these tools and help perpetual pavement design gain wider acceptance and use, there is a need for a webinar that covers these topics aimed at engineers and pavement type selection makers. This webinar is RCEP approved.
