6. CAUSES of DAMAGES on ASIAN ROADS
KEY FACTORS
• Overloaded trucks: Axle load x 2 Damage x 25 = 32 China: On the Tianjing-Shantan Expressways, 28-44% of trucks exceed the legal limit Vietnam: 30 -70% overload
• Slow heavy traffic: 90km/h to 30km/h Rutting x 5
• High service temperature: 45 to 60oC Rutting x 3
• Under designed road structure / Non reliable traffic data
• Non appropriate asphalt pavement performances: Based on 60/70 pen

7. WHY CHOOSING KBC HARD GRADE BITUMEN ?
PRO’s
BITUMEN
o Regular user: Australia o Experiences: Thailand, Vietnam, China o To come: Indonesia, Malaysia
Emerging Demand
o Base for Very hard grade (10/20 – 15/25)
EME2
HMA PERFORMANCES IMPROVEMENT o High Stiffness Modulus o High Rutting Resistance
Problem solving Cost Efficiency Extended service life
Sub Base Course Crusher Run
Base Course Crusher Run
Bituminous Base Course
Asphalt Wearing Course
Structural Reinforcement (BBME – GB4 - EME)
ASIA Tech 2015 Nov. 18 - 20, 2015 Bangkok Thailand
8 . OPPORTUNITY for KBC and the GROUP
• To initiate the change by using harder grades through:
• Seminar
• Workshop
• Feedback in High Performance HMA
• To provide sustainable solution
• To prove our professionalism in bitumen processing
• To catch up new markets
• To take the leadership in engineered and hard grades bitumen
• To become THE reference in South Asia / Pacific
ASIA Tech 2015 Nov. 18 - 20, 2015 Bangkok Thailand
9 . OUR STRENGTH
• A dedicated refinery to our core business
• The exclusivity for processing 100% naphthenic crudes
• Consistency in sourcing and quality
• Adaptability to the demand
• Capacity of production and shipping
• Competency of KBC teams and experience
• Sales teams
• Technical support from PD
ASIA Tech 2015 Nov. 18 - 20, 2015 Bangkok Thailand
10. PROPOSALS
• Top priority issues to focus on • Smell Scavenger • Smokes Blending
• To investigate production of very hard grades for EME
• Blowing column?
• Blending (with SAMI blown AC)
• Chemical modification
• More technical support to customers Customer Service
• To work more “Upstream” with local road authorities and customers through seminars and workshops. We should become the “catalyst” for better HMA
ASIA Tech 2015 Nov. 18 - 20, 2015 Bangkok Thailand
Transversal cooperation
11. CONCLUSIONS
• We secured the crude supply
• We upgraded our tool of production
• We now need to prepare the future for:
• HSE issues
• Diversified and “tailored” markets, source of bigger profits and market share
ALL TOGETHER WE CAN BECOME THE BEST RECONIZED BITUMEN
