On October 4th, 2024 in Hanoi, the Institute of Transport Science and Technology (ITST) held an annual scientific conference to celebrate its 68th anniversary, in line with the general trend of the transport industry, which is to deploy new technologies and materials to meet the increasingly high requirements of projects, while at the same time, develop sustainable technologies to achieve net zero emissions by 2050 as set by the Government.

The ceremony was attended by Institute Director Tran Bao Ngoc, Deputy Directors, representatives of the Ministry of Transport (MoT), state management agencies, research units inside and outside the industry, former leaders of the Institute, along with many scientists, experts, and representatives of partner businesses.

Young scientists of the ITST presented 8 papers, including special scientific reports on the topics of Initial research on the properties of 60/70 bitumen modified by waste engine oil/waste plastic and Experimental research on some technical indicators of asphalt concrete used for airport pavement. These studies not only meet the practical needs in the construction and maintenance of transport infrastructure but also affirm the role of the ITST as a key advisory unit for the MoT in the field of science and technology.

At this conference, Asphalt Distribution Company Limited (ADCo) was a sponsor, impressing guests with the drilled asphalt concrete sample at runway No. 3 - Bangkok International Airport, Thailand, constructed by its parent group TIPCO and COLAS. The asphalt concrete sample is 43 cm long, including all structural layers: the wearing course, binder course, and base course of the project.

Specifically, hard bitumen is used for a 33-cm thick base course with 4 layers of 9, 8, 8, 8 cm thickness and a 5-cm thick binder course to provide high elastic modulus and superior rutting resistance. The 5cm wearing course is designed as a gap-grade mix using Colflex^® PMB (Polymer Modified Bitumen) PG76, providing good bonding, rutting resistance, and high shear strength when aircraft take off and land while still ensuring safety factors, roughness, and high friction to meet ICAO standards.

In addition, the prime coat layer used EcoPrime^® emulsion, which has properties of fast curing and deep penetration. When applied, the product does not require heating that helps to reduce VOCs exposures impacting on the environment.

The asphalt concrete sample of Bangkok International Airport and other ADCo products such as emulsion for recycling technology EcoStab^®, 40/50 bitumen and PMB product lines attracted the attention of many delegates attending.

Along with the standards that will be issued after the topics are accepted (standards on High-Performance Pavement (HPP), Polymer Modified Asphalt (PMA)), in the coming time, the repair, upgrading and construction of new runways/taxiways will use asphalt concrete with fast construction time, low cost, quick and convenient maintenance, in line with the world trend of gradually replacing cement concrete.

ADCo Company is proud to be a pioneer in providing high-quality products, contributing to the sustainable development of the transportation industry in particular and the country in general. We always strive to achieve the goal of being a innovative solutions partner of customers and management units.
