高性能道面混凝土表面抗裂性能研究

Research on Crack Resistance of High Performance Concrete Pavement Surface

寒冷干旱地区机场道面铺筑水泥混凝土后会经常出现早期裂缝,针对这一问题,要选用既能减少混凝土早期开裂又能满足设计要求的混凝土材料,采用在普通混凝土中单掺合成纤维或粉煤灰以及合成纤维与粉煤灰复合的技术路线,研究配制高抗裂的高性能道面混凝土,采用平板法对其早期抗裂性进行试验验证,并在多个机场道面工程中进行了应用,取得了不错的抗裂效果。

Cold arid areas of airport pavement will often appear after the early cracks of cement concrete paving, to solve this problem, you should use both to reduce early cracked concrete concrete materials can meet the design requirements, the use of concrete in the ordinary single-doped synthetic or fly ash and fly ash and synthetic fiber composite technology roadmap, high-performance concrete prepared with high pavement cracking, using the plate method test to verify its early crack resistance, and in a number of airport Pavement Engineering were applied to obtain a good crack effect.
