BCSIR to use twister technology to build model roads


DHAKA, April 21, 2018 (BSS)-Bangladesh Council of Scientific and Industrial
Research (BCSIR) is going to use Japanese twister technology on a pilot basis
to build a model road to ensure a sustainable construction in the country.

BCSIR Senior Scientific Officer Dr Mohammad Nazrul Islam Bhuiyan today said
the road will be constructed in Dhaka city or its adjoining area for modeling
an initiative of promoting sustainable road constructions.

Bhuiyan, who has been tasked to coordinate the initiative, said Japan
Development Construction (JDC) Corporation provided the BCSIR with technology
and finance for the pilot project.

The BCSIR is now working to select a suitable area for constructing the
road, he said.

The council took the scheme with an expectation that the initiative will be
replicated across the country through different government and private
companies in building roads, river and road embankments, reclamation of
harbours, marine drives, railways and airport runways, he added.

The official said the BCSIR and JDC Corporation inked a memorandum of
understanding (MoU) on March 28 to carry out the pilot project.

BCSIR Secretary Md Khalilur Rahman and JDC Corporation President Takeo
Asakura signed the MoU on behalf of their respective sides at a function in
the presence of BCSIR Chairman Md Faruque Ahmed.

Earlier, he said, a four-member delegation headed by Faruque Ahmed went to
Japan on August 24, 2017 and observed the effectiveness of the twister
technology there.

Talking about the twister technology, the project coordinator said, it is
useful in constructing road both in rural and urban areas, river and road
embankments, reclamation of harbours, marine drives, railways and airport
runways through soil improvement.

The technology can improve any kind of soils, including sand and clay, by
recycling and fortify it for sustainable construction, Bhuiyan added.

“Same cost and time may require for construction using the twister method
comparing to the exiting one in Bangladesh. But durability of the structures
might increase to at least 100 years,” he said.

Terming the technology as cost effective and environment-friendly, the
BCSIR official said it increases the sustainability of the soil without
harming the ecology.

“As I observed the soil improvement process of the technology through
recycle, it was seemed to me that the method will help increasing
sustainability of the structures in our country,” BCSIR Superintending
Engineer Mohammad Monir Hossain Patwary told BSS.

Same materials that are generally used in construction work in Bangladesh
will be used in construction process using the technology, he said, but it
would increase the sustainability of the soil, particularly sand and clay.

However, the model road that is going to be built under joint venture would
attest the effectiveness of the technology in Bangladesh, Patwary said.

Lecturer of Accident Research Institute (ARI) of Bangladesh University of
Engineering and Technology Shahnewaz Hasanat-E-Rabbi said if the roads are
constructed sustainably, the number of accidents would be reduced as the
drivers could run their vehicles through smooth paths.

The sustainable construction also will reduce the maintenance cost of the
structures that will help the government utilizing the surplus fund in other
development projects, he added.
