| 摘 要： | 针对不同粒径再生混凝土的性能进行试验分析。试验结果表明：当骨料粒径#330～40mm时，路面再生混凝土的抗压强度最高，弹性模量略低，从而使路面混凝土再生综合性能表现最佳，进而达到新鲜混凝土路面的技术指标，而且也实现了废弃路面混凝土的再生利用。这对于保护环境、节约资源都有重要意义。

| Abstract: | The performance of recycled concrete in different size is analyzed. The results show that when the aggregate size is 30 -40 mm, the compressive strength of recycled concrete is the maximum and modulus of elasticity is ment spec protect the slightly lower, so the performance of recycled pavement concrete is best and the fresh concrete pave- fications are researched. The recycling of waste pavement concrete is achieved. It is important to environment and conserve resources |
