Technical guide – The use of standards for hot mixes
On 1 March 2008, the product standards in the NF P series will bedefinitively withdrawn and replaced by the new NF EN Frenchstandards derived from European standardization. This document explains the nomenclature and formulation of themixes generally used in France and how they correspond to Europeanstandards.

This document explains the nomenclature and formulation of themixes generally used in France and how they correspond to Europeanstandards. It also sets out the stages of the French mix design process. The series of European standards covers French mixes and othersbesides, for wearing courses, base courses and sub-base and road baselayers. It is therefore necessary to present the information in theEuropean standards to make it suitable for application in the Frenchcontext This technical guide makes it possible to perform this transcription. Itis divided into a number of sections which explain the references tostandards, the bituminous materials used in France, the type tests formixes, the characteristics of the aggregates, the fines, the coatingbinder and the use of reclaimed asphalt. The guide does not deal withrecommendations for laying, but explains where this information canbe found. The guide ends with a series of Annexes containing tables thatsummarize the mix formulations, the minimum characteristics of theaggregates, the performance that is expected of the various types ofmix, ending with a reclaimed asphalt information sheet.
