在介绍共振破碎原理以及共振破碎工艺的基础上,以南通经济开发区江韵路白改黑工程为依托,基于共振碎石化试验段共振破碎前后的弯沉、模量检测和粒径级配试验对共振碎石化效果进行评价,结果表明:共振碎石化后,形成了上层均匀性良好,级配接近碎石级配的碎石化层,下层存在裂缝但板体较好的破裂层的嵌锁结构层,基层强度介于道路的柔性基层和半刚性基层之间,在有效消除反射裂缝的同时保证了路面承载力。
Based on the introduction of the principle of resonant crushing and the process of resonance crushing, based on the white alteration project of JiangYun Road in Nantong Economic Development Zone, based on the deflection, the modulus detection and the particle size distribution before and after resonance crushing The results of the experiment show that the crushed-gravel layer with good upper-level homogeneity and gradation close to the gravel gradation is formed after the resonant crushing, but the rupture layer with good crack in the lower layer Of the embedded structure layer, the grassroots level between the grassroots and semi-rigid grassroots level between the road in the effective elimination of reflective cracks at the same time to ensure the bearing capacity of the road.
