The performance of glue laminated railway ties after 40 years of service in the main line track
1989 - IRG/WP 2325
Two series of horizontally glue laminated ties made of a softwood body and topped with a hardwood lamination were creosoted and installed in 1947 in a tangent and a curved main line track. The tests are now 40 years old and the excellent condition of the ties of these two series suggest that a service life of 50-60 years can be expected....

Performance of dip and pressure treated wood in termite ground proximity exposures in Hilo, HI, and Colombia
2008 - IRG/WP 08-30491
A number of preservative systems were evaluated for their ability to control termite attack when applied as both dip and pressure treatments. With dip treatments, better performance was observed with southern pine than spruce-pine-fir using the same solution strength treatment, probably as a result of the about 50% greater uptake with southern pine and associated deeper preservative penetration. B...

Categorization of 300 timber, bamboo and cane grown in Bangladesh based on their families, origins, growths, physical and mechanical properties
2009 - IRG/WP 09-10684
In this study the 300 timber, bamboo and cane plants grown in Bangladesh have been classified into various categories based on their taxonomic families, origin of species, rate of growth, color of wood, texture of wood, shrinkage of wood, equilibrium moisture content (EMC) of wood, flammability of wood, cutting and sawing properties of timber, finishing and polishing qualities of wood, machining p...

Comparison of moisture loss and its increment during the rehearsal process based on natural drying and water soaking application with or without sealing the trial discs of Common black poplar (Populus nigra L.)
2013 - IRG/WP 13-40639
This study was subjected to be set up to prove the pattern of moisture loss and moisture increment within the same wood samples prepared as the discs (30x23±3 cm diameter) with or without the bark intact during drying and in the duration of the water soaking application. In this concept, wood was exemplified by Common black poplar (Populus nigra L.) of the five 12 year old trees that are grown in...
