Performance of Cuplump Modified Binder (CMB) - HMA Containing Sasobit® Wax (original) (raw)

IOP Conference Series: Earth and Environmental Science

Abstract

Increase in traffic loads combined with an insufficient degree of maintenance in recent years has caused an acceleration and continuous deterioration of the road network globally. Hence, several types of measures may be effective in combatting these matters, such as, improved roadway design, use of better quality of materials and the use of more effective construction methods. The influence of warm mix additive (Sasobit®) on the performance of Natural Rubber Modified Binder based on cuplump was acquired. In this work, the influence of warm mix additive loading on cuplump modified binder (CMB) on softening point, penetration properties Marshall Stability, flow, and Marshall Quotient (Stability to flow ratio) were acquired. The dosage of natural rubber and additive was kept at 5% to 6% and 1% to 2% respectively for all binders. Results showed that the softening point increased while the penetration property decreased to approximately 40% indicating the effect of stiffening due to addi...
