In this study, laminated veneer lumbers were produced with rotary peeled veneers from eucalyptus, beech and poplar using urea-formaldehyde, melamine-urea-formaldehyde and phenol-formaldehyde adhesives. Air-dried density, equilibrium moisture content, thickness swelling, and water absorption were determined. The obtained data were evaluated with variance analysis. Results showed that adhesives type influenced equilibrium moisture content, and equilibrium moisture content of LVLs bonded with phenol-formaldehyde was the highest, and that of LVLs bonded with melamine-urea-formaldehyde was the lowest. In addition, results showed that tree species, adhesive type, and soaking time were effective significantly on the thickness swelling and water absorption
