摘　　要：研究了覆面膜颜色、厚度、灰分含量等因素对SBS改性沥青防水卷材抗风化开裂性能的影响,结果表明:覆面膜的厚度为改性沥青防水卷材抗风化开裂的主要影响因素,当厚度提升一倍时,其耐候性呈几何倍数提升;颜色和灰分为次要影响因素,选用黑色覆面膜并适当控制其灰分含量,可有效提升耐候性及抗风化开裂性能。The study investigates the influence of color,thickness and ash content of overlay film on the weathering crack resistance of SBS-modified asphalt waterproofing membranes.The results indicate that the film thickness is the primary factor influencing weathering crack resistance.When the thickness is doubled,the film's weather resistance results in a geometric improvement.Color and ash content are secondary factors.Selecting black overlay film and appropriately controlling ash content can effectively enhance weather resistance and weathering crack resistance performance.
