Building quality asphalt surface on high-speed motorways, heavy traffic loads, under hot weather conditions is an urgent requirement of the current transportation industry in Vietnam. The technology of manufacturing and supplying asphalt concrete is considered to be the weakest stage that needs to be overcome quickly to improve the quality of asphalt pavement. The article introduces and analyzes the advantages and advanced technology thinking, which has been developed and perfected for half a century in leading industrialized countries in the world, in order to produce and supply mixed products. Asphalt mixtures are properly graded components and have sufficient bearing characteristics and long-term stability under the impact of the environment according to the design and the requirements of technical standards. Applying this advanced technology in our country today is an objective and entirely feasible requirement, there have been the leading units to successfully apply, ensure successful and beneficial projects for business.Xây dựng mặt đường nhựa đảm bảo chất lượng trên các đường ô tô tốc độ cao, tải trọng giao thông nặng, dưới điều kiện thời tiết nóng là yêu cầu cấp bách của ngành giao thông vận tải nước ta hiện nay.
