沥再生工后抗滑性能预测模型

Anti-skid Performance Prediction Model of RejuvaISealTM after Construction

沥再生由于具有施工快、价格低廉以及表观效果好等优点而被广泛使用,但是工后路面又存在抗滑性能降低的潜在不利因素。为了掌握沥再生施工后沥青路面抗滑性能的变化规律,保障路面行车安全,通过在上海南北高架开展现场试验的方式,对沥再生措施施工后路面摆值进行长期连续跟踪观测,同时利用GM(1,1)灰色预测模型结合现场实测摆值数据,建立了精度不低于二级的沥再生措施施工后抗滑性能衰变模型,为今后合理使用沥再生措施提供参考借鉴。

RejuvalSealTM is widely used because of its advantages such as fast construction, low price and good apparent effect.However,there are potential disadvantages of anti-skid performance of pavement after construction.In order to grasp the changing rule of asphalt pavement anti-skid performance after the construction of RejuvalSealTM and ensure the safety of pavement driving,the pavement pendulum value after the construction of RejuvalSealTM was continuously monitored for a long time through tests field on the north and South viaducts in Shanghai.At the same time.using GM(1.1)grey prediction model combined with field measured pendulum data.a decay model of anti-skid performance after construction of RejuvalSealTM is established.which can provide reference for rational use of RejuvalSealTM in the future.
