Structural behaviour of Kekatong glued laminated timber railway sleepers under ‘sleepers static performance test’

The availability of good quality timber logs from higher Strength Groups (SG) such as SG1 and SG2 which are naturally durable with large diameter are limited and initiated the increasing in timber log price. The used of non-durable timber which is not properly treated resulting decreasing in its life span during services.
