Use of high modulus bituminous materials

The French design method for airfield flexible pavement provides a total equivalent pavement thickness. The actual thicknesses of materials are determined by assigning each material a coefficient of equivalence representative of its mechanical properties.

This note recalls the principles of the design method and presents the testing by the STBA of experimental pavements built with high modulus bituminous concrete (BBME) and high modulus bituminous mixes (EME) which validates the use of these materials in airfield pavements.
