Riyadh, the capital of Saudi Arabia, suffers from traffic congestion like other modern societies, during peak hours but also all day long, even without any incidents. To solve this horrible problem, various efforts have been made Active Traffic Management (ATM) aspect. Ramp metering (RM) is one representative methods ATM and has already proven its value in many locations worldwide. Unfortunately, RM not yet fully implemented Arabia. This research aimed to assess applicability a freeway...

In order to facilitate the effective implementation of MEPDG, researchers concentrate on quantifying local material properties, with a particular emphasis pavement layer moduli.
