Increasing quarry capacity, removing difficulties in materials for highway construction through Binh Dinh

Binh Dinh province has increased the capacity of some quarries to meet the demand for construction materials for the eastern North-South expressway component projects passing through the area.

Lack of materials for asphalt concrete construction

Responding to the 500-day-and-night movement to speed up progress, in the last days of November, despite the continuous rain, the construction site of the Hoai Nhon - Quy Nhon expressway through Binh Dinh province was still very urgent.

At package 12-XL, PV witnessed 6 construction teams with about 150 workers of Phuc Loc Group working tirelessly. A series of trucks lined up to transport crushed stone aggregate materials to dump on the main route.

The contractor of the expressway through Binh Dinh is looking for a source of quality stone to construct the project.

Two workers quickly drove the bulldozer to push the stone blocks out and spread the surface evenly. Three rollers from behind continuously rolled the layers of aggregate until they reached the required density. Just like that, the work was coordinated smoothly as if it had been pre-programmed.

By the evening, another 500m of the highway surface had been paved with crushed stone. Despite the unfavorable weather, all bridge items on the route had been completed. Four other construction teams were paving with crushed stone, reaching more than 80%.

Mr. Mai Huy Cu, Deputy CEO of Phuc Loc Group Joint Stock Company, said that on the assigned volume, the unit has almost finished laying crushed stone aggregate and is urgently laying a layer of cement-reinforced crushed stone aggregate (CTB).

The unit is surveying the source of stone materials that meet the standards for asphalt pavement by next December.

"The biggest difficulty now is the source of stone materials for asphalt paving. The unit has surveyed many places, but many mines are not of good quality. Materials at Son Hai Group's mine in Phu My district can be used for paving, but the reserves are low.

We have surveyed and planned to buy stone in Khanh Hoa for use. However, the transportation must be done by sea, the distance is long, the price of materials increases many times", Mr. Cu shared, at the same time said, according to calculations, the unit needs about 40,000m3 of stone to use plastic mats.

Many contractors are in need of large sources of stone to pave highway surfaces.

Undertaking the construction of 5km of road at the Hoai Nhon - Quy Nhon expressway project, Mr. Nguyen Thanh Luan, Commander of the Traffic Construction Corporation 8 (Cienco 8) said that the unit is also considering a plan to mobilize stone sources from Khanh Hoa or Quang Binh to serve the construction of asphalt concrete items.

"This will cause difficulties for contractors because of the long distance and high costs," Mr. Luan worried.

Increase mine capacity to serve the North-South expressway

The North-South Expressway through Binh Dinh province is 118km long, including 3 component projects: Quang Ngai - Hoai Nhon, Hoai Nhon - Quy Nhon and Quy Nhon - Chi Thanh.

According to the investor's report, the demand for stone for all 3 expressway sections in the province is about 6.5 million m3.

Of which, about 4.5 million m3 were taken from commercial mines, 1.05 million m3 were used from the rock excavated from tunnel No. 3 (bordering Quang Ngai and Binh Dinh) and 894 thousand m3 were used from 5 excavation sections on the main route.

Mr. Nguyen Van Hoa, Deputy Director of the Department of Transport of Binh Dinh province, said that the province has introduced to the investor to survey 19 licensed commercial quarries with reserves of 29 million m3, meeting the request.

Currently, the investor is using 6 mines with an annual exploitation capacity of 772 thousand m3 to serve the project.

The contractor constructing the expressway through Binh Dinh said that they carefully checked the quality of the stone to ensure the quality of the project later.

According to the approved design survey documents, the stone used as construction material was taken from the excavated stone of tunnel No. 3 of the Quang Ngai - Hoai Nhon expressway.

However, assessing that this stone source is unusable, the investor has proposed to increase the capacity of 4 mines (Binh De, Kim Thanh, Truong Thinh, Hoai My Cooperatives), storing an estimated amount of more than 1 million m3 within 2 years to serve the project.

"In response to the above proposal, the People's Committee of Binh Dinh province has decided to increase the capacity of the mineral exploitation license granted to Hoai My Trading Company Limited in Hoai Chau Bac commune, Hoai Nhon town to serve the construction of the North-South expressway.

In particular, Hoai My Trading Company Limited is allowed to adjust and increase 50% of its mining capacity from 41,500m3 of various types of construction stone/year to 62,250m3 of various types of construction stone/year. The requested raised part is only used for the construction of the North-South expressway.

Binh Dinh province also allows to increase by 50% the capacity of quarrying stone for construction materials from more than 136,000m3 of raw stone/year to more than 204,000m3 of raw stone/year for the quarry in the area west of Binh De pass (Hoai Chau Bac commune, Hoai Nhon town) of Truong Thinh Company to serve the construction of the expressway through the area", a representative of Binh Dinh Department of Transport informed.
