Flyovers Relieve Congestion in Myanmar

A great deal of the Ammann product line was at work during the recent construction of an overpass or “flyover” in Yangon, Myanmar, in Southeast Asia.

Traffic in the city is increasingly becoming more congested, so the flyover was created above the location where several roads converge.

Handling the project was Shwe Taung Development Co. Ltd., one of Myanmar’s leading construction companies. Founded in 1990, the company employed more than 6,000 last year.

“Our mission is to inspire lives through responsible investment and sustainable development,” said Mr. Ye’ Myint, Chief Executive Officer at Shwe Taung Group, with headquarters in Yangon. “The company continues to shape the future of the living and working environments in Myanmar by developing real estate projects and infrastructure developments aiming to transform the lives of the Myanmar people.”

Ammann equipment continues to help make that a reality. Shwe Taung owns an Ammann AFT 500 Asphalt Paver, an AP 240 T2 Pneumatic Roller, an AV 70 X Articulated Tandem Roller, an ARW 65 Walk-Behind Roller and an ASC 100 Soil Compactor.

Providing the product support was Htun Nay Wun Thitsar, the local Ammann Dealer that is well-regarded for its after-sales efforts.

Key Project

The Tamwe Flyover, with a cost of $19.2 million, is a Y-shaped structure that connects several roads and moves traffic above the congested streets below. Flyovers are increasingly common in Myanmar, with another having been completed the previous year.

“Yangon’s population increases day by day and the people were facing traffic problems almost daily, so the regional government built the flyover to ease chronic traffic conditions,” said Mr. Ye’ Myint.

The flyover is 600 metres long. The AFT 500 F Asphalt Paver worked at the width of the flyover road when possible. Only a single lift of asphalt was required.

Haul trucks carried 5 tons to the jobsite from the plant, which was 4 km away. A tamping and vibratory screed was utilised.

The Screed Assist System helped provide consistency and a level surface. The system is an e-hydraulic device that unloads the weight of the screed, thereby enabling an increase in paving depth. Transferring the weight of the screed onto the rear tracks also improves traction.

The paver worked at a pace of 5 metres per minute, even while pulling at the extensive lift. An AV 70 X Articulated Tandem Roller provided breakdown compaction. It typically made between two and four vibratory passes. The AP 240 T2 Pneumatic Roller made 16 passes during intermediate compaction. The tandem roller then followed with another two to four passes, with no vibration.

Mr. Ye’ Myint said. “The management likes the combination of the Ammann paver and rollers because the project was finished on time, and the Ammann brand can certainly support our business development.”
