Permeable asphalt concrete pavement structure and raw material composition thereof
The invention discloses a permeable asphalt concrete pavement structure and a raw material composition thereof. The raw material composition of the permeable asphalt concrete pavement structure comprises a component A for forming fine-grained permeable asphalt concrete of an upper surface layer and a component B for forming coarse-grained permeable asphalt concrete of a lower surface layer, the component A is prepared from the following components in parts by mass: 4 to 7 parts of asphalt, 90 to 97 parts of aggregate, 1 to 15 parts of mineral powder and 0.1 to 0.4 part of fiber modifier; the nominal maximum particle size of the component A is not greater than 8mm; the component B is prepared from the following components in parts by mass: 3 to 6 parts of asphalt, 92 to 98 parts of aggregate, 1 to 6 parts of mineral powder and 0.1 to 0.4 part of fiber modifier; and the nominal maximum particle size of the component B is 10 to 16 mm. The obtained permeable asphalt concrete pavement structure has good low-temperature cracking resistance and good noise reduction performance, is safe and reliable, has long service life, and is suitable for being applied to cold regions or frozen regions.
本发明公开了一种透水沥青混凝土路面结构及其原料组合物。该透水沥青混凝土路面结构的原料组合物包括用于形成上面层细粒式透水沥青混凝土的组分A和用于形成下面层粗粒式透水沥青混凝土的组分B；所述组分A包括以下质量份的组分：沥青4‑7份、骨料90‑97份、矿粉1‑15份和纤维改性剂0.1‑0.4份；所述组分A的公称最大粒径不大于8mm；所述组分B包括以下质量份的组分：沥青3‑6份、骨料92‑98份、矿粉1‑6份和纤维改性剂0.1‑0.4份；所述组分B的公称最大粒径为10‑16mm。所得透水沥青混凝土路面结构可以兼顾良好的低温抗开裂性能和良好的降噪性能，安全可靠且使用寿命长，适用于在寒区或冰冻区应用。
