The addition of oil palm fruit fibre to the matrix result in an increase in the water absorption value for all fibre contents except at 0.5% oil palm fruit fibre which maintains an average of the same absorption at all tire crumb content except at 40%. The increase in absorption when oil palm fruit fibre are added is due to the high void content of the fibre causing more absorption of water during hydration. The best absorption recorded at 0.5% is due to the fact that the quantity of the fibre is insignificant in the matrix and hence does not affect the hydration
