LPC Bituminous Mixtures Design Guide- Appendix F – Product family descriptionAC-BBM Asphalt Concrete – Béton Bitumineux MinceDefinition Bituminous mixture in accordance with EN 13108-1 characterized by anaverage application thickness of between 3 cm and 5 cm. The materialis designed to yield surface courses and possibly binder courses. Theparticle size distribution is most often gap-graded. Categories A, B, Cdepend on the “gap” of the grading curve.Classification by the resistance to permanent deformation.Identification AC10 or AC14 according EN 13108-1Surface or (binder) courseEmpirical approachDesignation AC-BBMA, AC-BBMB or AC-BBMC class 0AC-BBMA, AC-BBMB or AC-BBMC class 1AC-BBMA, AC-BBMB or AC-BBMC class 2AC-BBMA, AC-BBMB or AC-BBMC class 3Usualaggregatecharacteristics(minimal values)SurfacecourseCoarseaggregateFineaggregateor All-inAddedFillerMain characteristicsLA 20 or LA 25 , M DE 15 or M DE 20, PSV 50Fragmentation,Wear,Polishing resistanceAngularityCoarse;Fine aggregateGrading requirementFlakinessFine contentGrading requirementMethylene blue valueStiffness by ring andball, Void of drycompacted fillerC 95/1E CS 35G C 85/20 or G 25/15 ;FI 25 ; f 2G F 85 ; G TC 10 ; G A 85MB F 10∆ R&B 8/16 ; V 28/38V max13Type of binderPaving grade bitumen 50/70 or 35/50Polymer modified Bitumen 45/80-60 or 40/100-65Minimum binder contentB min5,00,063 5 to 80,250 10 to 23Grading : %Sieve in 2,0 27 to 37mm 4,06,3 30 to 40D 90 to 100Water sensitivity Method B (I/C) ITSR 70Gyratory Category of AC-BBM AC-BBMA AC-BBMB AC-BBMC40 gyrations V min6 V max11 V min7 V max12 V min8AC- AC- AC- AC-ClassificationBBM 0 BBM 1 BBM 2 BBM 3Gyratory 10 gyrations V10G min11 Not applicableNb of 3 000 cycles P 15cyclesWheel tracking10 000 cycles P 15test30 000 cycles No perf.P 10Large device Void content AC-BBMA determined {Vi= 7% Vs = 10%}60°C of slab AC-BBMB or{Vi= 8% Vs = 11%}CLevel 0Level 1Level 2- 167 -
