Below is the list of working group members:Yves BROSSEAUD, Laboratoire Central des Ponts et ChausséesYves GANGA, Laboratoire Régional des Ponts et Chaussées de Clermont-FerrandRené HIERNAUX, Laboratoire Régional des Ponts et Chaussées de Saint-QuentinJean-François LAFON, Laboratoire Régional des Ponts et Chaussées de ToulouseFrancis MOUTIER, Laboratoire Central des Ponts et ChausséesClaude ROGER, Laboratoire Régional des Ponts et Chaussées de StrasbourgPatrick VAN GREVENYNGHE, Laboratoire Régional des Ponts et Chaussées– d’ Aix-en-ProvenceAlso providing valuable assistance with this publication were:Chantal de la ROCHE, Laboratoire Central des Ponts et ChausséesFlorence PERNOT-MOREAU, Laboratoire Régional des Ponts et Chaussées de l’EstParisienFrançois TRAVERS, Laboratoire Central des Ponts et ChausséesLouisette WENDLING, Laboratoire Régional des Ponts et Chaussées d’AutunNicole VERCHERE, Laboratoire Régional des Ponts et Chaussées de l’Est ParisienPreface contributed by:Jean-Michel PIAU, Technical Director for Pavements and Road Safety, LaboratoireCentral des Ponts et Chaussées
LPC Bituminous Mixtures Design Guide– Preface –PrefaceLPC Bituminous mixtures Design GuideJean-Michel PIAUThis guide is intended to collate and set forth the knowledge accumulated byFrance's Ministry of Public Works' Scientific and Technical Network (RST) in the fieldof designing hot bituminous mixtures.It provides a description of:⎯ the bituminous mixtures design method used by RST; and⎯ the rules of practice and expertise introduced in asphalt mix design studies,for the purpose of efficiently obtaining materials capable of meeting a seriesof predefined specifications.This document has been compiled with an educational aim of transferring knowledgeand standardizing methods currently applied within the various Ponts et Chausséeslaboratories.It would be beneficial however to expand the document scope over the near term bycontributions from the world of industry to give rise to the publication of a "Frenchmethod for road material design". This effort would allow covering the entire range oftechniques implemented throughout France capable of being shared among ourEuropean and international partners.We felt it appropriate to use this guide's introductory section to recall the mainobjectives inherent in bituminous mixtures design methods and then to explain thepredominant constituents based of a streamlined formulation, making it morestraightforward to grasp long and complex processes that often imply developingsuch methods. It then becomes easier to understand the diversity of methods in useacross the world. Highlighting the key stakes involved and the breadth of this topicstill to be explored also serves to justify the permanence of research resourcesallocated to improving and optimizing mix design methods.Along the same lines, a number of preliminary considerations will be provided belowon another aspect of this "bituminous mixtures design" focus; these concern morespecifically the mix design studies actually being conducted.–3 –
