徐州机场应用混凝土道面新技术 2003年,徐州观音机场跑道道面工程应用混凝土道面施工新技术——拉毛压槽法处理水泥混凝土塑性状态表面的揉浆、抹面采用木抹抹面,提高道面微观纹理;制作平均纹理深度能达到0.6毫米的毛刷;制作压槽机使道面槽形成槽间距17毫米,槽深3毫米,槽宽上口4毫米,下口3.5毫米呈梯形,压槽滚轴重量限制在25公斤。该技术具有设备简单,施工方便,纹理清晰,抗滑性能良好等优点。该技术已在徐州观音机
Xuzhou Airport application of new technology of concrete pavement 2003, Xuzhou Guanyin Airport runway pavement engineering application of new technology of concrete pavement - Lama pressure trough plastic cementing state of the surface treatment of kneading, wiping the surface with wood wiping the surface to improve pavement Micro-texture; the average depth of the texture can be achieved 0.6 mm brush; making pressure groove machine to make pavement groove spacing of 17 mm groove, groove depth of 3 mm, the width of the mouth 4 mm, 3.5 mm was trapezoidal mouth, Roller weight limit at 25 kg. The technology has the advantages of simple equipment, convenient construction, clear texture and good skid resistance. The technology has been in Xuzhou Guanyin machine
