SOG间断半开型级配与RST高黏度改性结合料各自优势组合,使混合料在高温稳定性能、低温抗裂性、水稳定性以及抗剪切、抗疲劳等重要路用性能都达到良好的指标,相比于另一种常用的AC-20应力吸收层,GSOG一20混合料一方面应力吸收效果以及高低温性能均超过对方,另一方面结构整体造价也比对方低,且由于整体厚度适中,受标高等外部环境影响较小,值得大力推广。目前浦东建设的GSOG应力吸收层技术在上海、浙江、江苏等地都已成功应用,效果得到业主和施工单位的高度认可。
SOG intermittent half-open grading and RST high-viscosity modified binder each combination of advantages, so that the mixture at high temperature stability, low temperature crack resistance, water stability and anti-shear, anti-fatigue and other important road performance are good Compared with the other commonly used AC-20 stress absorption layer, GSOG a 20 mixture on the one hand stress absorption and high temperature performance than the other side, on the other hand, the overall cost of the structure is also lower than the other party, and as a whole Moderate thickness, less affected by the elevation of the external environment, it is worth promoting. At present, the construction of GSOG stress absorption layer technology in Pudong has been successfully applied in Shanghai, Zhejiang and Jiangsu, and the effect is highly recognized by the owners and construction units.
