Risk of lack of sand for highways

From now to 2025, the Government is expected to simultaneously deploy about 400 km of highways in the Mekong Delta with a total investment of over VND 100,000 billion. However, the difficult question today is sand where to make roads, when now this kind of material has begun to be scarce.

At the Cha Va intersection at the beginning of Can Tho – My Thuan highway, the site clearance is delayed for 1 year, so the contractor is rushing to speed up the progress. However, the amount of sand received each day is only from 5,000 – 7,000 blocks, making the leveling work slow.

“Now we need a volume of sand that is three times more than the output of the two provinces of An Giang and Dong Thap at this time,” said Mr. Nguyen Van Luong, 36 Corporation.

My Thuan – Can Tho Expressway has a length of nearly 23 km. It is expected that phase 1 will be completed in 2023. At this time, the project needs about 300,000 – 400,000 m .3 Filled sand, equivalent to 12,000 – 15,000 m3 everyday. Due to supply difficulties, the project can only build up 5,000 – 7,000 m per day3 sand.

“The Board as well as the Ministry proposes An Giang and Dong Thap provinces to increase the productivity of the current sand mines, secondly, to add a new mine to supply the My Thuan – Can Tho highway project”, said Mr. Pham Duc Trinh. , Director of Can Tho – My Thuan Expressway Project, information.

Currently, many other projects are also behind schedule due to scarcity of sand. This is worrisome, because from now until 2025, the Mekong Delta needs a huge amount of sand to build 400 km of highways. According to many experts, saline sand in estuaries and sea mouths can be an additional source.

“Dinh An channel has dredging about 7.2 million m per year3 salted sand, but this amount of sand pours into the sea. That is very wasteful. If we exploit this source, it will add a large amount of sand for construction,” said Dr. Tran Huu Hiep, economist in the Mekong Delta.

On the other hand, 48.5 million tons of ash and slag from 29 coal-fired power plants in the country can be fully utilized for highway leveling.
