Pavement super-tough wearing layer and hot paving process thereof
The invention discloses a pavement super-tough wearing layer and a hot paving process thereof. The pavement super-tough wearing layer comprises a bonding lower layer and a wearing upper layer. The bonding lower layer comprises the following components, by weight: 40 to 50 parts of asphalt, 30 to 60 parts of xylene, 2 to 15 parts of acrylic resin, 2 to 15 parts of polyurethane, and 2 to 8 parts ofSBS thermoplastic styrene-butadiene rubber; the wearing upper layer comprises the following components, by weight: 80 to 110 parts of aggregate, 5 to 9 parts of high-toughness and high-elasticity composite modified asphalt, and 3 to 6 parts of mineral powder. Besides, the hot paving process of the pavement super-tough wearing layer comprises a paving step of a bonding lower layer and a paving stepof a wearing upper layer. After improvement of the components of the bonding lower layer and the wearing upper layer, the pavement has super-strong reflection crack resistance, low-temperature cracking resistance and fatigue cracking resistance.
本发明公开了一种路面超韧磨耗层及其热铺工艺，路面超韧磨耗层包括粘结下层和磨耗上层；粘结下层包括按重量份计的组分：沥青40‑50份；二甲苯30‑60份；丙烯酸树脂2‑15份；聚氨酯2‑15份；SBS热塑性丁苯橡胶2‑8份；磨耗上层包括按重量份计的组分：集料80‑110份；高韧高弹复合改性沥青5‑9份；矿粉3‑6份；路面超韧磨耗层的热铺工艺包括：粘结下层的铺装步骤和磨耗上层的铺装步骤；通过粘结下层和磨耗上层的组分改进，使得路面具备超强的抗反射裂缝性能、抗低温开裂性能、抗疲劳开裂性能。
