Present Status and Progress

The test track on Sawada Railway Station to Hatnur Dam Road (MDR-15) near Bhusaval, District Jalgaon (Maharashra) at Chainage 00/00 to 00/900 was constructed in December 2003. Total length of the test track is divided in three parts. Each part is of 300 metre in length. First part is constructed by using only yellow stones. Second part is constructed by using yellow stones & black basalt (50:50%). Third part is constructed by using only black basalt in WBM road.

The test track was constructed as per the standard specifications of PWD Maharashtra state. On WBM surfaces 20 mm premix carpet with liquid seal coat (Hot Mix Hot Laid) was provided. Post construction observations are being taken twice in a year (pre-monsoon & post-monsoon) for three years. Final post construction observation is due in December 2006.
