High-performance Chip Seal application for a major south Vietnam highway project.
The HW1A road in Binh Thuan province showed many cracks in the wearing course under heavy-duty service. The customer decided to use the Chip Seal technique to protect the surface under heavy traffic. CRS-2P, Chip seal emulsion from ADCo, has been applied to maintenance road construction in the BOT Phuong Nam project. KM 1661 + 600 HW1 BINH THUAN province for the area of about 125,000 sqm trial with Tan Ha customer in July 2021. This high-performance CRS-2P provides good bonding between old pavement and new aggregate surfaces as 
well as providing a shorter curing time, to waterproof and protect the pavement, safe and simple application with reasonable pricing.   Project name: HW1A Binh Thuan maintenance project using CRS-2P - Chip Seal

First Highway project using 40/50 for the surface course. Maintenance and upgrading project on HW13 from KM62+700 to KM95+000 in Binh Phuoc province, was started in May 2019 under BOT contract. The existing asphalt pavement was showing important rutting after many years of service under severe traffic and climate condition. Due to Budget constraints, the use of PMB was not feasible. Therefore, project owner decided to consider alternative products that could provide added value on rutting resistance with limited impact on construction budget. 40/50 KBC Naphthenic was then proposed for the structural overlay on HW13 pavement.   Project name: HW13 BOT Products: KBC Naphthanic 40/50 and EcoStab® Years: 2019-2020 Location: Binh Phuoc Investors:  Binh Phuoc Infrastructure Construction and Investment Joint Stock Company Contractors: Infrasol Company Limited Consultant: 568 Investment & Consulting Joint Stock Company Scope of project: 32km of 4 lanes Construction section:  FDR 15cm including old asphalt and base course.

A major first in cold-in-place recycling in Vietnam ADCo has been involved in the rehabilitation of a 32-km segment of Highway 13 by using cold in-place recycling technique with EcoStab® emulsion for an important heavy-duty traffic road located in Southern Vietnam, connecting Ho Chi Minh City to Cambodia. The road pavement was initially constructed in 2012, but after 8 years of service under heavy traffic, the existing asphalt pavement started to show serious structural problems as well as rutting. After several attempts to repair the road, the Toll Road Operator decided to perform deep structural rehabilitation of the pavement. The cold-in place recycling technique was selected since the client was looking for a cost-effective solution that allows a 100% reuse of in-situ materials with minimum disturbance to the traffic.   Project name: ​​​​​​NH13 Binh Duong - Binh Phuoc (Cold in-place Recycling) Years: 2020 Location: Binh Phuoc Investors:  Binh Phuoc Infrastructure Construction and Investment Joint Stock Company Contractors: Infrasol Company Limited Consultant: 568 Investment & Consulting Joint Stock Company Scope of project: 32km of 4 lanes Construction section: FDR 15cm including old asphalt and base course.
