The trend worldwide tends to substitute soft binders with harder grades, more adapted to sustain heavy traffic and high service temperatures. This paper focuses on the presentation of features and benefits of using 40/50 through case studies from two heavy-duty highway projects in Vietnam.
ADCo is involved in the rehabilitation of a 32-km segment of Highway 13, an important heavy-duty traffic road located in Southern Vietnam, connecting Ho Chi Minh to Cambodia. The road pavement was initially constructed in 2012. However, after 8 years of service under heavy traffic, the existing asphalt pavement started to show serious structural problems and rutting.
ADCo, has been involved in the rehabilitation of a 32km segment of Highway 13 by using Cold in-place recycling technique with EcoStab® (ADStab®) emulsion for an important Heavy-duty traffic road. The Cold-in place recycling technique has been selected as the client was looking for a cost-effective solution that allows to re-use 100% of the in-situ materials with minimum disturbance to the traffic.
A company trip is an effective connection channel through which businesses and schools meet and develop relationships to achieve a common goal. Moreover, a field trip creates a favorable environment for students to gain practical knowledge and skills—an important foundation for career development.To continue the series of company trips for students of the University of Transport, on November 10, 2020, we were happy to welcome students from Class K58_DB02 to visit the ADCo-Hai Phong depot.
In October 2020, Central Vietnam in general and Chan May Terminal, in particular, were hit by four consecutive storms that caused damage to people, including ADCo employees living and working in this area. Immediately, the company leaders urged everyone to donate and share the difficulties of their colleagues. The total amount raised amounted to US$ 10,894 (equivalent to VND 252,632,000). The representatives of ADCo also organized a visit to 12 families of ADCo employees who suffered from storm damage.
Following the success of previous field trips, on 24thOctober 2023, ADCo welcomed 30 students, Faculty of Engineering, University of Transport and Communications (UTC) to visit Hai Phong Depot. This is a useful activity, equipping the students with knowledge and practical experiencethat helps them gain a deeper understanding of asphalt materials and asphalt products such as Polymer Modified Bitumen, emulsion… as well as future career development directions.
ADCo/Tipco applied Microsurfacing technique on HW21B which has intensive traffic with speeds up to 80km/h and heavy vehicles to extend the service life of the road a couple of years, restore the skid resistance while protecting the pavement from moisture and improve the traffic safety
ADCo is launching a high-performance water-reactive cold mix asphalt for permanent road repairs in harsh environments (wet, humid, heavy traffic) inspired by one of the Colas products portfolios named “Watercon®”, which has been developed and used globally.
Microsurfacing using EcoGrip® (cationic quick-setting polymer-modified emulsion from ADCo) shows good performance even after over 1 year of service. The skid resistance and macrotexture are stable, and the pavements do not show any signs of cracking or shoving.
On June 6th 2023, Asphalt Distribution Company Limited (ADCo) cooperated with The University of Da Nang – University of Science and Technology (UD-DUT) and Da Nang Bridge and Road Association to hold the seminar "Asphalt Solutions for Road Maintenance” at Novotel Hotel, Da Nang City. Attending the seminar, the Organizing Committee was honored to welcome the representatives of Ministry of Transport, Vietnam Road Department, Regional Management Unit No.3, and representatives of local Departments of Transport, the Project Management Units, Consulting companies and contractors, close customers of ADCo; the experts, doctoral professors of Faculty of Construction, Bridge and Road at the University of Transport and Communications (UTC), The University of Da Nang – University of Science and Technology (UD-DUT).
