The invention relates to permeable ecological concrete for roads and a manufacturing method thereof, the permeable ecological concrete is prepared from the following raw materials in parts by weight: 1500-1700 parts of aggregate, 30-60 parts of admixture, 340-400 parts of cement, 0-50 parts of rubber fragments, 100-120 parts of water and 13-17 parts of reinforcing agent, the aggregate is natural aggregate and lightweight aggregate, the natural aggregate is pebbles and comprises 300-340 parts of small stone and 1200-1350 parts of medium stone according to the particle size, and the admixture is water. The lightweight aggregate is 0-100 parts of ceramsite; the preparation method comprises the following specific steps: preparing raw materials, mixing dry materials, adding water and stirring for the first time, adding a reinforcing agent and stirring, and adding water and stirring for the second time. The concrete has the advantages that a small amount of small stones and a large amount of medium stones are matched to ensure the strength and water permeability of the concrete, and the rubber fragments are added to enhance the breaking strength of the concrete; the rubber fragments are tire fragments obtained by waste recovery, and the admixture is silica fume, fly ash or superfine slag powder, so that the waste is reutilized, and energy conservation and environmental protection are realized; ceramsite is good in water permeability, and water permeability of concrete is convenient to adjust.
本发明涉及一种道路用透水型生态混凝土及其制作方法，按重量份数计，原料包括骨料1500～1700份、掺合料30～60份，水泥340～400份、橡胶碎片0～50份、水100～120份、增强剂13～17份，所述骨料天然天然集料和轻骨料，所述天然集料为石子，并按照颗粒大小包括小石300～340份、中石1200～1350份，轻骨料为陶粒0～100份；具体步骤包括准备原材料、干料混合、加水一次搅拌、加增强剂搅拌、加水二次搅拌；本发明具有如下优点：本发明采用少量小石与大量中石配合保证混凝土的强度与透水性，加入橡胶碎片，从而增强其抗折强度；橡胶碎片采用废物回收的轮胎碎片，掺合料采用硅灰、粉煤灰或矿渣微细粉，使废料二次利用，节能环保；陶粒透水性好方便调节混凝土的透水性。
