Pavement super-sticky wearing layer and normal-temperature paving process thereof
The invention discloses a pavement super-sticky wearing layer and a normal-temperature paving process thereof. The pavement super-sticky wearing layer comprises a bonding lower layer and a wearing upper layer, the bonding lower layer comprises the following components in parts by weight: 40-55 parts of asphalt; 30 to 50 parts of xylene; 2-15 parts of acrylic resin; 2 to 15 parts of polyurethane and 2-8 parts of SBS thermoplastic styrene-butadiene rubber; the normal-temperature paving process comprises the following steps: paving the bonding lower layer, namely mixing the asphalt, the xylene, the acrylic resin, the polyurethane and the SBS thermoplastic styrene-butadiene rubber, spraying, and standing until the surface is not stuck to a wheel so as to form the bonding lower layer, sprinkling, and standing until the surface doses not stick a wheel to form the bonding lower layer; paving the wearing upper layer, namely adding water into a aggregate, high-viscosity composite modified emulsified asphalt and cement, mixing, paving on the bonding lower layer, and rolling and forming after paving; and completing paving of the pavement super-sticky wearing layer. According to the pavement super-sticky wearing layer, the components of the pavement super-sticky wearing layer are improved, and the pavement super-sticky wearing layer is good in high-temperature stability and high in bondingstrength and shear strength after being paved.
本发明公开了一种路面超粘磨耗层及其常温铺装工艺，路面超粘磨耗层，包括粘结下层和磨耗上层；粘结下层包括按重量份计的以下组分：沥青40‑55份；二甲苯30‑50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；常温铺装工艺包括：粘结下层的铺装步骤：将沥青、二甲苯、丙烯酸树脂、聚氨酯和SBS热塑性丁苯橡胶混合后洒布，然后静置至表面不粘轮，形成粘结下层；磨耗上层的铺装步骤：将集料、高粘复合改性乳化沥青、水泥加水混合，然后摊铺在粘结下层上，摊铺完毕后碾压成型；完成路面超粘磨耗层的铺装；路面超粘磨耗层，通过改进路面超粘磨耗层的组分，经铺装后得到高温稳定性好，粘结强度、抗剪强度高。
