Having attained the approval of the Vietnam Bridge and Road Association (VIBRA), Transport Material Equipment Supply Joint Stock Company (TRANSMECO) in the collaboration with the Ho Chi Minh city Bridge Road Port Association held the seminar on “Bitumen Emulsion Technology” in order to implement the VIBRA’s 2016-2020 plan on applying the advance technologies into the road construction and pavement distress treatment. The event took place at Ho Chi Minh city University of Transport on April 14th 2016.
The seminar on “Bitumen Emulsion Technology”
The seminar saw the presence of Mr. Ngo Duc Thinh – Chairman of VIBRA, Former Deputy Minister of Transport; Mr. Doan Minh Tam – Vice Chairman of VIBRA cum Head of Science and Technology Committee, Former Head of Transport Science and Technology Institute; Mr. Ha Ngoc Truong – Vice Chairman of Ho Chi Minh City Bridge Road Port Association; Assoc. Prof. Dr Nguyen Van Thu – Director of Ho Chi Minh City University of Transport and representatives of the companies, construction companies, departments of transportation, consultants for designing and supervising, technical experts in the Southern region of Vietnam.
Mr. Vu Kim Bang – Chairman of Director Board cum General Director of Transmeco delivering the opening speech
The seminar mentioned three significant issues of applying the bitumen emulsion technology into the road construction, repair and maintenance: (1) the role of the bituminous materials in the pavement construction; (2) the technology of producing the polymer modified bitumen emulsion of Transmeco; (3) the technology of producing bitumen and bitumen emulsion sprayers of Van Xuan Joint Stock Company.
The quality of asphalt concrete pavements is one of the topics that always draw the attention of the managing units, contractors and road engineers. The tack coat between the asphalt concrete layers has the great impact on the quality of pavement structure. In his presentation on the role of the bituminous materials in the asphalt concrete pavement, Assoc. Prof. Dr. Doan Minh Tam indicated the importance of the tack coat, several requirements to the tack coat and especially focused on the types of bitumen emulsions and liquid bitumen used for the tack coat. The application of the engineered emulsion (EE) and polymer modified bitumen emulsion (PME) have the high temperatue stability and coating ability between the asphalt concrete layers, which considerably enhances the stability as well as strength of pavements and reduces the deformation such as cracking, rutting, depression.

In order to help the participants have a look at the polymer modified bitumen emulsion, Dr. Ngo Thanh Hai – Head of R&D department of Transmeco presented a research on producing the polymer modified bitumen emulsion for asphalt concrete pavmement construction and maintenance. Transmeco is the first Vietnamese company to succeed in producing the quick setting polymer modified bitumen emulsion CQS-1hP with Transmeco’s advanced production line. The company is highly appreciated for the product’s quality as well as professional service by Elsamex (an Indian company). This type of bitumen emulsion is used for microsufacing – the technology is newly applied for the road construction and maintenance in Vietnam. Furthermore, Transmeco has successfully done research and produced the NovaBond polymer modified bitumen emulsion that has several properties such as the high coating ability, quick setting and is used as the ultra –thin bonded wearing course.

Beside the good quality materials and advance technology, there is also another factor which builds up a perfect tack coat. That is the bitumen emulsion sprayer. At the event, Mr. Nguyen Bong – Head of Technical Department of Van Xuan JSC (VXC) introduced about bitumen emulsion, bitumen, MC sprayer. VXC is the first Vietnamese company to do research and manufacture bitumen emulsion sprayers that comply with the French fogging spray technology. During the past years, technical characteristics of the bitumen emulsion sprayer have been improved to better satisfy the demand of the market. Thanks to these improvements, the clogging of nozzles and the bitumen emulsion remainder are removed.

The seminar on “Bitumen emulsion technology” is the opportunity for Transmeco to introduce the new construction materials, high quality products to the customers, contractors, investors in the Southern region of Vietnam. During the seminar, many customers and partners were interested in the company’s brand and products, particularly the bitumen emulsion sprayer and polymer modified bitumen emulsion, which creates the basic conditions for Transmeco to expand the market, promote the products and affirm the prestige of Transmeco – the pioneer in doing research and producing the materials and machinery for the infrastructure construction in Vietnam.
