Damaged roads under repair
15:48, 2014/08/14
Four out of seven road work projects have completed repairs of subsided highways that required fixing shortly after being opened.
The remaining work would be completed by next Wednesday, head of the Department for Management of Traffic Work Construction and Quality Tran Xuan Sanh said.
At a meeting on Monday, Sanh said that repairs to four roads; the section of National Highway No1A from Ben Thuy Bridge to Ha Tinh Province, the section of National Highway No2 from Ha Noi to Thai Nguyen Province, the National Highway No5 and the 35-km long route avoiding Thua Thien Hue Province, had finished.
Three other projects; the Uong Bi-Ha Long section of National Highway No18, the route avoiding Vinh City, and the enlargement of National Highway No1A passing Ninh Binh Province, were currently in progress.
"The department will have a report on the cause of the subsidence on these routes," he said.
To ensure the quality of repaired roads, Minister of Transport Dinh La Thang required the department to work with the Viet Nam Road Administration to re-examine repair jobs on these projects and the Gie Bridge-Ninh Binh, Ha Noi-Lao Cai Highway and Thang Long Boulevard projects.
The department would have to issue the time of maintenance for these routes by the end of this month, he said.
In June, a 14-member inspection team, led by Deputy Minister of Transport Nguyen Ngoc Dong, was set up to examine why many sections of new roads and highways had subsided so quickly after a short time of opening.
The team would study and propose solutions to address subsided roads and ask experts from scientific institutions and related agencies to help.
International experts have discussed the problem of subsidence and cracks on transport projects, citing temperature changes, overloaded vehicles, construction methods and building material quality for the collapse of construction works.
Numerous measures have been taken to fight the problem, including strict oversight over heavily-loaded vehicles, asphalt quality and designing and building processes.
