Asphalt Characteristics of Concrete Asphalt Mixed to Reduce Early Damage in Flexible Pavement

Abstract


 
 
 
 Pavement roads in Indonesia often suffer premature damage. Efforts to overcome road damage need to be done by using pavement materials suitable for the climate in Indonesia. This research discusses the comparison of Pertamina asphalt 60/70 and Shell asphalt 60/70 in the concrete asphalt mixture. The variation of the bitumen content used in this study was 4%, 4.5%, 5%, 5.5%. From the test results, it can be concluded that Shell asphalt 60/70 penetration is relatively better in terms of the considerable penetration value, softening point, stability value, flow, and Marshall Quotient, which are higher than Pertamina's 60/70 penetration asphalt.
 
 
 

Asphalt Mix Compressive Stress-Strain Behavior: An Analytical and Experimental Study of Variable Influence

“…In Indonesia, there have been numerous instances where the service life of roads was reduced by 25.94%, equivalent to 4.3 years, or even by 1.5 to 2 years from the intended 10-year lifespan. According to statistics from the Department of Public Works and Public Housing [8][9][10], only 62% of Indonesia's roads are in good condition, with the remaining roads either lightly damaged or severely deteriorated. The increasing traffic density is a major contributing factor to road damage and reduced longevity.…”
