在高速公路建设中,桥隧占设计里程的比例越来越大,伴随标准化设计的推广与安全等级的提高,混凝土标号越来越高,对地材特别是碎石的质量要求也有所提高,反击破碎石也已在高标号砼中全面得以应用。本文结合广东省某高速公路建设,从碎石加工现状及反击破碎石生产标准化效果对比等几个方面出发,探讨反击破碎石标准化施工,以及在反击破碎石在标准化施工工艺及石场标准化建设上进行的有益尝试与改进。
In highway construction, the proportion of bridges and tunnels in design mileage is increasing. With the promotion of standard design and the improvement of safety grade, the concrete grades are getting higher and higher, and the quality requirements on the ground materials, especially the gravel, have also been raised. Anti-crushed stone has also been fully applied in high-grade concrete. In this paper, a highway construction in Guangdong Province, from the status of gravel processing and countermeasures against standardization of crushing stone production several aspects, to discuss the standardization of crushed stone countertops, and in the counterattack of broken stone in the standardization of construction technology and the standardization of stone farms Useful attempts and improvements.
