The invention relates to a tyre tread (1) for a heavy civil engineering vehicle with an improved compromise between resistance to mechanical attacks caused by stone ground and grip on muddy ground. The tread (1) comprises five rows (41, 42, 43), the five rows (41, 42, 43) are separated in pairs by longitudinal cuts (51, 52) and are distributed in a transverse direction (YY ') in a central row (43), two intermediate rows (42) and two side rows (41), the blocks (31, 32, 33) in a single row (41, 42, 43) are at least partially separated in pairs by transverse cuts (61, 62, 63), each transverse cut in the side rows (41) being a transverse groove, and the longitudinal cuts (51, 52) are arranged in the longitudinal direction (YY'). Each transverse cut (62) in the middle row (42) is a transverse non-penetrating groove (621) or a transverse sipe (622), the transverse non-penetrating grooves (621) and the transverse sipes (622) being alternately arranged along the longitudinal direction XX ', each inner longitudinal cut (52) separating two adjacent middle and middle rows (42, 43), respectively, is a longitudinal groove.

    本发明涉及一种用于重型土木工程车辆的轮胎胎面(1),其具有在对多石地面所引起的机械攻击的抗性与泥泞地面上的抓地性之间的改进折衷。胎面(1)包括五个排(41、42、43),所述五个排(41、42、43)成对地由纵向切口(51、52)分隔开并且沿着横向方向(YY’)以中心排(43)、两个中间排(42)和两个侧排(41)分布,单个排(41、42、43)中的花纹块(31、32、33)至少部分地通过横向切口(61、62、63)来成对地分隔开,侧排(41)中的每个横向切口为横向沟槽,中间排(42)中的每个横向切口(62)为横向非贯穿沟槽(621)或横向刀槽(622),横向非贯穿沟槽(621)和横向刀槽(622)沿着纵向方向XX’交替地布置,相应地分隔两个相邻的中间排和正中排(42、43)的每个内部纵向切口(52)为纵向沟槽。
