Founded in 2007, King Ho Tai International Co.,Ltd. is the first asphalt concrete factory in Taiwan to use natural gas instead of heavy oil fuel, and also first installed Tail gas treatment process to filter polluted air. King Ho Tai group explores the feasibility of a resin additive used in asphalt production, hoping to improve the conventional process conducted for asphalt production using a large number of heat sources and reduce carbon emissions and environmental pollution. The use of reclaimed asphalt pavement (RAP) added with resin can not only avoid the heat generated during traditional asphalt production, but also improve durability, increase service life, and reduce maintenance requirements.
