The invention discloses a pavement reinforcement structure. The structure comprises a water-permeable asphalt surface layer, a lower sealing layer and a plurality of semi-rigid base layers, wherein alayer of geonet is arranged between every two adjacent semi-rigid base layers, the number of all the geonets is at least two, auxiliary positioning pieces used for assisting in positioning the positions of the geonets are arranged on the geonets, an Nth semi-rigid base layer is paved, then a layer of geonet is paved by adopting a full paving method, positioning is assisted by utilizing the auxiliary positioning pieces, a lower sealing layer between a lower surface of the water-permeable asphalt surface layer and an upper surface of the top semi-rigid base layer is set, an Mth layer of semi-rigid base layer is laid, and a second layer of gabion box is laid. If necessary, the laying process can be repeated till construction of the semi-rigid base layers is finished. The structure is advantaged in that fatigue, reflection, temperature and differential settlement crack diseases can be reduced, the service life of the pavement is greatly prolonged, the maintenance period is prolonged, so whole life cycle cost of the pavement is lower than that of a non-reinforced pavement.
本发明公开了一种路面加筋结构，包括：透水性沥青面层、下封层及若干半刚性基层，相邻半刚性基层之间设有一层土工网，所有土工网的数量为至少两层，土工网上设有用于辅助定位土工网位置的辅助定位件。铺筑第N层半刚性基层，然后采用满铺方法铺设一层土工网，利用辅助定位件辅助定位，下封层设置于透水性沥青面层的下面与最顶层的半刚性基层的上面之间。铺设第M层半刚性基层，并铺设第二层格宾网。如有需要，可重复上述铺设过程直至半刚性基层施工完毕。本发明可以减少疲劳、反射、温度和不均匀沉降裂缝病害，使路面使用寿命大幅度提升，延长了维修周期，因此路面的全寿命周期费用低于不加筋路面。
