Application of Asphalt Concrete using Limestone with Cement & Admixture
Vietnam is one of the countries in the world that will likely suffer from climate change predictions. The natural state of severe seasonal weather patterns in Vietnam, when combined with heavy trucks, makes the current conventional types of asphalt concrete are no longer able to bear the load. This results in common defects, such as rutting resistance and fatigue cracking of the current asphalt concrete roads surfaces. This article aims to introduce a type of high strength asphalt concrete using limestone filler, combined with cement and an adhesion additive that will help to solve the mentioned problem. The place of the pilot project was on a ten kilometers road (Km 1613+00 to Km 1623+00) on the National Highway number 1, which suffers from the heaviest traffic loads. The asphalt concrete was designed with a Marshall- Bailey Modification Method. After four years of use, the road was recently tested and remains in an operational and stable condition. There are many solutions proposed to apply the solution of high-intensity asphalt concrete using limestone filler combined with cement and admix. Wetfix®BE increased adhesive is the best solution due to the product’s cost-effectiveness, the availability of materials: like sand and stone. The asphalt concrete is high in strength, heat resistant, rutting resistance and fatigue cracking.
