Paving method of granular wood fiber modified asphalt pavement
The invention discloses a method for paving a granular wood fiber modified asphalt pavement, which comprises the four steps of mixing, paving, compacting and checking and accepting, the pavement paving method specifically optimizes the composition, proportion and preparation method of a modified asphalt material, so that the obtained modified asphalt material has better thermal stability, workability and compactness; the pavement construction operation of the granular wood fiber modified asphalt pavement is fully mechanically carried out through a high-power full-width paver and a double-steel-wheel oscillating road roller, so that various properties of the asphalt pavement can be obviously improved; therefore, the paved pavement has higher flatness and compactness, better driving comfort and longer pavement service life, and the paving method is high in construction efficiency, good in universality, low in construction cost and suitable for large-scale application in construction of granular wood fiber modified asphalt pavements of domestic high-grade highways and urban artery roads.
本发明公开了一种颗粒状木质纤维改性沥青路面的铺设方法，包括混料、摊铺、压实和验收4个步骤，该路面铺设方法不仅针对性的优化改性沥青材料的组成、配比以及制备方法，使得到的改性沥青材料具有更好的热稳定性、和易性和密实性；还通过大功率全幅摊铺机与双钢轮振荡式压路机全机械化进行颗粒状木质纤维改性沥青路面的铺设施工作业，能够显著提高沥青路面的各项性能，从而使铺设得到的路面具有更高的平整度和压实度、更好的行车舒适性、更长的路面使用寿命，且该铺设方法施工效率高，普适性好，施工成本低，适合在国内高等级公路、城市干道的颗粒状木质纤维改性沥青路面施工中大规模应用。
