市政道路共振碎石化的适用性及关键问题——以南昌双港东大街为例

Applicability&Key Problems of Municipal Roads Resonance Crushing:Taking Shuanggang East Ave.in Nanchang as an Example

随着经济迅猛发展、持续增长的交通量加剧早年建成的水泥混凝土路面(含白改黑沥青混凝土路面)破坏,旧水泥混凝土路面的改造迫在眉睫。以市政道路南昌双港东大街工程为例,通过调查旧路面使用状况及管线分布,从技术适应性、经济性等角度,确定共振碎石化后加铺沥青面层的实施方案,以达到既改善旧路面行车性能,又经济环保的效果。最后,指出共振碎石化施工中的关键点,为类似市政道路改建提供借鉴。

With the rapid economic development&the increasing traffic volume,the destruction of the cement concrete pavement(including the white to black asphalt concrete pavement)built in the early years is intensified,and the reconstruction of the old cement concrete pavement is imminent.Taking the municipal road Shuanggang East Ave.project in Nanchang as an example,by investigating the use condition of the old pavement&the distribution of pipelines,the implementation scheme of adding asphalt pavement after resonance crushing is determined from the perspective of technical adaptability&economy,so as to improve the driving performance of the old pavement&achieve the effect of economy and environmental protection.Finally,the key points in the construction of resonance crushing are pointed out,which can provide reference for the reconstruction of similar municipal roads.
