Abstract
A top-quark reconstruction method for CLIC is described. The reconstructed events are used to measure the e+ e- -> t \bar{t} cross-section as well as the forward-backward asymmetry. The results suggest that the relative measurement accuracy for the cross-section will be 1.4 % and for the asymmetry 4.2 % for 1 ab^{-1} of data.
