Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventors found that the method of vibrating and compacting on the spot to form the cushion layer of the refurbished road surface will cause damage to the subgrade during the vibrating process, which will easily cause subsidence of the subgrade. Even if the pavement is refurbished, the refurbished Pavements also have a short lifespan and require regular maintenance or replacement

Abstract

The invention relates to a municipal road old cement pavement treatment method which is applied to the field of urban construction. The method comprises the following steps: excavating, crushing, grinding, screening and blanking and compacting. The crushing device has the effects that the base layer is not damaged in the whole crushing process, and the service life is prolonged.

Description

technical field [0001] The application relates to the field of urban construction, in particular to a method for treating old cement pavements of municipal roads. Background technique [0002] Concrete pavement or cement pavement is a common road type of municipal roads, and cracks will appear after long-term use. The cracks on the concrete pavement in the related art generally adopt repairing means to prolong the service life of the pavement. [0003] Commonly used repair methods include repairing only for cracks or vibrating and compacting the whole pavement containing cracks before laying new concrete on it, that is, the old concrete pavement is directly vibrated and compacted on the spot to form Cushion for new pavement, refurbish the pavement, prolong the service life of the pavement. [0004] In view of the related technologies mentioned above, the inventors found that the method of vibrating and compacting on the spot to form the cushion layer of the refurbished road...
