Additional paving reconstruction design and construction method suitable for microwave active maintenance
The invention discloses a paving reconstruction design and construction method suitable for microwave active maintenance, and relates to the field of road microwave heating active maintenance. The paved and modified pavement structure comprises a pavement surface layer, a buffer layer and a metal grating which are arranged above the old cement concrete base layer from top to bottom. According to the design method for paving and transforming, parameters of the metal grating and the buffer layer are quantitatively designed, so that microwave energy can be effectively utilized by the pavement structure. When the pavement is subjected to microwave maintenance, energy is retained in the asphalt layer through the reflection effect of the metal grating with the specific side length on microwaves, so that the energy utilization rate is increased; and meanwhile, the grading of the buffer layer is quantitatively designed based on the maximum shear strength, so that the interlayer stability of the pavement structure is ensured, and the performance strength of the modified pavement is further improved. And in addition, before the surface layer is paved in the construction, a microwave maintenance vehicle reheating procedure is introduced, so that interlayer bonding of the pavement is guaranteed, the quality of an additional paving reconstruction project is improved, and the service life of the road is prolonged.
本发明公开了一种适用于微波主动养护的加铺改造设计与施工方法，涉及道路微波加热主动养护领域。所述加铺改造后的路面结构包括在旧水泥混凝土基层上方自上而下设置的铺装层面层、缓冲层与金属格栅。所述加铺改造的设计方法对金属格栅与缓冲层的参数进行定量设计，使路面结构可有效利用微波能量。在对路面进行微波养护时，通过特定边长金属格栅对微波的反射效用，将能量留存于沥青层中，提高能量利用率；同时基于最大抗剪强度定量设计缓冲层的级配，保证了路面结构的层间稳定性，进一步提升改造路面的性能强度。且本发明在施工中面层铺设前，引入微波养护车复热工序，保障路面层间粘结，提高加铺改造工程的质量，延长道路服役寿命。
