In a previous work, a polymer having a low softening temperature was used as a binder of wood-chip and sand pavement system to prevent the crack formation in the pavement. Although the polymer prevented the crack formation, the mechanical properties such as durability and elastisity of the pavement were decreased. This means that there is a trade-off problem between the crack formation and the mechanical properties. <BR>In this work, the effects of softening temperature of the binder on the mechanical properties of the wood pavement have been investigated. It is found that the value of marshall stability decreases and the amount of dispersal of composite materials in the pavement increases with decreasing softening temperature of the binder.
