Method for determining optimal distribution opportunity for integration of prime coat and seal coat of road
The invention discloses a method for determining the optimal spraying opportunity of integration of a prime coat and a seal coat of a road. The method comprises the following steps: preparing a semi-rigid base mixture according to design requirements, and laying a semi-rigid base; respectively preparing a prime coat material and a seal coat material according to design requirements, and laying a prime coat and a seal coat; preparing an asphalt lower surface layer mixture according to design requirements and paving an asphalt lower surface layer; the method comprises the following steps: preparing a shear test piece on a semi-rigid base asphalt pavement formed by combining and spreading a permeable layer and a sealing layer at different spreading opportunities, respectively carrying out shear tests, and carrying out multi-stage verification on shear test results, so as to determine the optimal spreading opportunity for integrating the permeable layer and the sealing layer of the road. The optimal distribution opportunity combination of the prime coat and the seal coat can be accurately formulated, the construction efficiency is improved, and the maintenance cost is reduced; the determined distribution opportunity combination of the prime coat and the seal coat does not cause cracking of the semi-rigid base layer, and the interlayer adhesion between the semi-rigid base layer and the asphalt lower surface layer is firm enough, so that the service life of the road is prolonged.
本发明公开了一种道路透层和封层一体化最佳洒布时机的确定方法，包括以下步骤：按照设计要求配制半刚性基层混合料并铺设半刚性基层；按照设计要求分别配制透层材料和封层材料并铺设透层和封层；按照设计要求配制沥青下面层混合料并铺设沥青下面层；在由不同洒布时机组合洒布透层和封层而形成的半刚性基层沥青路面上制取剪切试件，并分别进行剪切试验，同时对剪切试验结果进行多级验证，即可确定道路透层和封层一体化最佳洒布时机。本发明能够准确制定透层和封层的最佳洒布时机组合，提高施工效率，降低维修成本；所确定的透层和封层洒布时机组合，不会导致半刚性基层开裂，半刚性基层与沥青下面层的层间黏结性足够牢固，进而提高了道路使用寿命。
