Lalitpur, May 24:

A two-day workshop for engineers and division chiefs of the Department of Roads (DoR) organised by the Strengthened Maintenance Division Programme (SMDP) of the DoR concluded here today.

The programme was held to disseminate information about the application of a new type of bitumen, Otta Seal. The organisers said the Otta Seal technology is cost-effective and can be used for roads built on low cost.

According to the deputy director general of the DoR, Kamal Raj Pandey, some 27 per cent of the total 17,000 km roads are graveled while 31 per cent is earthen.
