LPC Bituminous Mixtures Design Guide– Appendix G - Glossary –TermSymbol orAbbreviationUnitDefinitionCommentsMix formulationComposition of a single mixture expressedas target composition. It may be expressedas “input target composition” or as “outputtarget composition”EN 13108 seriesMixed fillerFiller of a mineral origin mixed calciumhydroxide.EN 13043NaturalaggregateAn aggregate from mineral source whichhas been subjected to nothing more thantransformation other than mechanical.EN 13043Non-connectingvoidsVoids in a test specimen open at one face,yet unable to reach the other face.Noxiouspotential of finesSee harmfulness of fine aggregates.Occluded voidsVoids in the test specimen that do not openonto any of the specimen faces.Output targetcompositionExpression of a mix formulation in terms ofthe constituent materials and the mid pointgrading and soluble binder content to befound on analysis. This will usually be theresult of a production validation.EN 13108 seriesParticle sizedistribution orgrading analysisPavement% The dimensional distribution of grain sizes,expressed in terms of mass percentagepassing through a specified series ofsieves. The analysis is carried out inaccordance with EN 933-1 for aggregatesin general and with EN 12697-2 foraggregates stemming from strippingoperations.Structure, composed of one or morecourses, to assist passage of traffic overterrain.EN 13043EN 13108 series- 188 -
LPC Bituminous Mixtures Design Guide– Appendix G - Glossary –TermSymbol orAbbreviationUnitDefinitionCommentsPaving bitumenBitumen used to coat mineral aggregate foruse in the construction and maintenance ofpaved surface. In Europe, the most usedgrades are defined by needle penetrationat 25°C, up to a value of 900 1/10 mm.EN 12597Percentage oflaboratory voidscharacteristic ofthe bituminousmixturePVL % Value deduced by the mix designer, basedon void percentages measured on the testspecimens produced in the laboratoryusing various means of compaction.Percentage ofvoidsv % The air void is the pocket between thebitumen coated aggregate particles in acompacted bituminous specimen. The airvoid content or percentage of voids is thevolume of the air voids in a bituminousspecimen, expressed as a percentage ofthe total volume of that specimen.EN 12697-8Percentage ofvoids filled bybitumenVFB % Binder volume as a ratio of total voidvolume in the granular skeleton, expressedas a percentage.EN 12697-8Percentage ofvoids in themineralaggregateVMA % Percentage of the pore and intersticevolume in the granular skeleton as a ratioof total specimen volume. This valueincludes the percentage of voids in themixture and the percentage volumeoccupied by the binder.EN 12697-8PigmentablebitumenA special bitumen category characterizedby a low asphaltene content, whichfacilitates the coloration of asphalt mixesthrough adding pigments.EN 12597PolymermodifiedbitumenBmPModified bitumen materials are bituminousbinders whose properties have beenaltered through the use of a chemicalagent, which when introduced into theEN 14023- 189 -
