LPC Bituminous Mixtures Design Guide– Appendix G - Glossary –TermSymbol orAbbreviationUnitDefinitionCommentsAir-slaked limeProduct derived through a curing processusing a very pure limestone.NF P 98-101All-in aggregateAn aggregate consisting of a mixture ofcoarse and fine aggregates; it can beproduced without separating into coarseand fine aggregates or by combiningcoarse and fine aggregates. Forbituminous mixtures 0/4, 0/6 may beusually used.EN 13043AngularityCharacteristic of aggregates with respectto the edges present on each grain.Angularity ofcoarseaggregatesC 100/0C 95/1C 90/1C 50/10C 50/30C DeclaredCharacteristic of aggregates with respectto the edges present on each grain.According to EN 13043, angularity ischaracterized for coarser alluvial or marineaggregates by completely-crushed orsemi-crushed grain categories, along withfully-rounded grains.Coarseaggregatesderived from solidrock lie incategory C 100/0Angularity offine aggregatesAngularity(former standard)Angularity(former standard)Crushing ratioAngularity(former Frenchstandard)Crushing indexE CS38E CS35E CS30E CSDeclaredAccording to EN 13043, angularity ischaracterized for fine aggregates by flowtime categories.Angularity had been evaluated by eitherthe crushing index (CI) or the crushingratio (CR) (former standard XP P18-540).RC - Ratio between the smallest dimension ofthe original coarse aggregate submitted tothe initial crushing and the D value of theresultant aggregate.IC % Percentage of elements in excess of D ofthe resultant aggregate contained in theoriginal material submitted to crushing.These measuresare no longerstandardized, yetstill do appear inbibliographies.These measuresare no longerstandardized, yetstill do appear inbibliographies.These measuresare no longerstandardized, yetstill do appear inbibliographies.Asphalt concretefor airfieldpavementsAC-BBAAsphalt concrete for airfield pavements(continuous grading curve AC-BBA C orgap-graded grading curve AC-BBA D), inaccordance with EN 13108-1.EB-BBA in theNF EN version- 176 -

The material is designed to yieldsurface courses and possibly bindercourses. The particle size distribution ismost often gap-graded. Categories A, B, Cdepend on the “gap” of the gradingcurve.Classification by the resistance topermanent deformation.EB-BBM in theNF EN versionAsphaltConcrete-BétonBitumineux àModule ÉlevéAC-BBMEBituminous mixture in accordance with EN13108-1 whose stiffness is higher than thatof a BBSG mixture and designed to yieldsurface or binder courses with a thicknessof 5 cm or greater until 9 cm.EB-BBME in theNF EN versionAsphaltlimestoneA sedimentary rock impregnated onsite bynaturally-occurring bitumen.- 177 -
