ASPHALT BUTON
Cost Effective Solutionfor Road Construction
LAWELE PENETRATION MACADAM
BRAM = Buton Rock Asphalt MacadamBRAM = Processed Lawele Asbuton and ready to use for penetration macadam or other constructions Low Water Content (Max. 5%)Fine granular size (Max. 1 cm)
BRAM Penetration Macadam
Suitable for rural roads (low-med traffic load) 15% cheaper than conventional penetration macadamMeaning that the length of the road built increases 15% than conventional penetration macadamNo additional petroleum asphalt needed (using 100 % Asbuton BRAM)
Benefits
Labour intensiveMore economicAvailable budget can be used to lengthen the road built
BRAM LAPEN
BRAM Penetration Macadam
With the same budget, the cost for developing 1 km conventional penetration macadam can be used for developing 1.2 km BRAM penetration macadamCost savingSolution for making quality roads affordableTarget development can be achieved faster

COLD MIX APLICATION
Cold mix Application / Ton MixMaterial : BRAM 120 kg
Cutback/Emulsion Asphalt 35 kgAggregate 0.78 m³
Tool : Pan MixerSpreading : Asphalt Finisher or Manually
Cold mix construction with BRAM is more economical ± 12 % than conventional cold mix construction
COLDMIX APLICATION- BRAMCold Mix
BRAM + Cut Back Mixing Material Cold Mix Product
Compating
Coldmix Mixture Procedure
BRAM + Cutback are heated at a temperature of 120-135 ° C for ± 15’
Aggregates are mixed within a Pan mixer
BRAM + Cutback are poured onto aggregates in the Pan mixer
The mixture is spreading manually on the road
Asphalt is compacted by Baby Roller
Application of Penetration Macadam ( LAPEN )
LAPEN Application/M2
Material : Base Aggregates 110 kgBRAM 15 kgFine Aggregates 2 Kg
Tools : Manual & CompactorSpreading : Manually
Lapen construction with BRAM is cheaper ± 15 % than conventional penetration macadam (using
virgin asphalt/oil asphalt)
System COLD MIX / Penetration Macadam System is suitable for making rural roads
Benefits :Cheaper tools’ investment Ideal for light to medium traffic Easy to apply and done manually (labour intensive – social benefit)The mixture result can be stored & re-use for up to 1 month thereafterSaving the budget for rural development roads
