A tire tread (1) for a heavy construction plant vehicle, and aims to improve both its ability to not retain stones in its voids, during off-road use, and its ability to dampen the noise that it generates, during on-road use. At least one longitudinal groove (6) of the tread (1) has a longitudinal distribution of protuberances (7), and any protuberance (7) has a height H′ at least equal to 0.9 times the depth H of the groove (6) and has a first portion (71), having a height H1, a width W1 and a thickness T1, and a second portion (72), having a height H2, a width W2 and a thickness T2, satisfying the relationships: H′=H1+H2, 0.6*H′<=H2<=0.9*H′, W2>=0.25*W, T2<=min(3 mm; 1/3*T1), W1>=0.5*W, T1>=H1.
