NAT NOTTINGHAM ASPHALT TESTING SYSTEM - ASPHALT PHYSICAL TESTING

The Nottingham Asphalt Tester (NAT)

• CEN PrEN 13108/12697-26
• CEN PrEN 13108/12697-25
• CEN PrEN 13108/12697-24


NATs have become essential to laboratories, universities, oil companies, regional laboratories, contractors and consulting engineers, worldwide. Trials have demonstrated that NAT test results give excellent correlation with other test methods such as bending beam and wheel tracking.

The NAT provides the most inexpensive and userfriendly means of measuring and assessing the mechanical properties of asphaltic paving materials on a routine basis. It is designed to derive the maximum information about a material using either cores cut from the highway or laboratory moulded specimens.

Application
  • Mix design
  • Quality control
  • End product specification
  • The assessment of raw materials
  • Failure investigation
  • Pavement assessment
