Marshall Tests For Asphalt Concrete Wearing Course Asb Lawele Containing Capsule Calsium Alginate as Self-Healing Additive

Abstract

Self-healing on pavement is solution to reduce the handling of road damage without doing heavy construction. Calcium Alginate capsules are mixed in AC-WC (Asphalt Concrete Waring Coarse) Asb Lawele as an added ingredient to healing from cracks. Marshall Test specification is reference to assess the pavement can use pavement Asphalt Concrete. Optimum Asphalt Content of 6.2% is used to make AC-WC Modification Mix Asb Lawele with Calcium Alginate. AC-WC Asb Lawele contains 2% Asphalt from Buton Island and 4.2% Asphalt Pen.60/70. The percentage of Additive Addition of Calcium Alginate Capsules ranging from 1% to 2% of the combined weight with a different oil/water composition of each calcium alginate capsule. There is similarity of IR spectrum between asphalt binder and Calcium Alginate capsules, allowing strong bonding if reviewed from Nitrogen group. However, with the addition of calcium alginate capsules showed a decrease in Marshall Stability but still within the limits of fairness, it was proven that the higher the percentage of additive capsules the lower the marshall stability, but didn’t have a significant effect on flow, while the VMA and VIM continued to increase as the percentage of Additives increased so that VIM out of the specifications on AC-WC Asb Lawele.
