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

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
