Cement firm tests alternative way for building roads
TCL Guyana Inc. (TGI), last weekend demonstrated the use of one of the latest technologies in road construction when the company partnered with the Ministry of Public Works to effect road repairs using the soil cement stabilization technique.
The pilot project, the company said yesterday, was conducted at the junction of Water and Princes Streets, Georgetown, where the area of road was in a severe state of deterioration.
Work being done at the junction of Water and Princes Streets, last weekend.
This rehabilitation work followed a July 2013 meeting with Minister of Public Works, Robeson Benn and staff of his Ministry, where approval for pilot projects to demonstrate the soil cement stabilization technology was given. The works included extensive repairs over the weekend.
TGI disclosed that asphalt and other unusable materials were removed.
“A sub-base was laid by stabilizing the existing material that remained, mixing it with cement and water, rotovating the mixture and compacting it. The base layer was then placed above the sub base where crusher run was also stabilized with cement. The surface was then sealed using a bitumen sealant. The works were carried out by B and J Civil Works.”
TCL Group Civil Engineer, Avaleen Mooloo, was on hand to oversee and lend technical advice for the process.
“I am confident that the newly stabilized road will be stronger than the normal flexible roads. Although some raveling of the surface is expected due to the constant trafficking of heavy-duty vehicles, coupled with the fact that the asphalt surface had not been installed, we anticipate that the road will stand up longer with time. This strip will be monitored for its longevity by Ministry and TGI personnel, as is the norm with demo strips.”
TGI also disclosed that as part of its strategic plan to improve sales, it has been pushing for the use of cement in the construction of roads and with its parent company, TCL, has held a number of awareness sessions for government officials, students from the University of Guyana and technical institutes, contractors, engineers and even individual private sector companies.
During those sessions, the technologies for using cement in road construction were explained. It was also emphasized that cement-based roads are more durable and have a substantially lower life-cycle cost.
“TGI remains committed to being a reliable supplier of quality cement to the Guyana market, and views the dissemination of information on best practices in the use of cement and concrete as a major part of its responsibility.”
Local engineers and the administration in recent years have been examining alternatives to the traditional way of building roads.
