为解决南方秋冬季道路被动抑冰滞后和效率低等问题,研发了主动型高黏疏水抑冰雾封层材料.通过正交理论设计、层次模型分析法进行综合性能评价,确定了增黏剂、疏水剂的最佳用量,采用多性能试验评价了路用性能和抑冰性能,确定了抑冰剂的最佳用量.研究结果表明:相比于乳化沥青基材,综合设计得到的最佳掺量高黏疏水雾封层材料的黏聚性和疏水性分别提升了 55.7％、144.3％.抑冰剂掺量为9％～12％时,雾封层材料储存稳定性较好,最佳洒布量为0.06 g/cm2时,固化性能和抗滑性能明显提升,达到最佳平衡状态.抑冰剂掺量与电导率呈显著线性相关,多次浸水循环后,高黏疏水抑冰雾封层材料具有缓释持久性.最佳抑冰剂掺量为9％时,雾封层材料抗凝冰效果达到最佳.
Design and Performance Evaluation of High Viscosity Hydrophobic Deicing Fog Seal Material
To solve the problems of delayed passive deicing and lowdeicing efficiency on roads in winter,an active high viscosity hydrophobic deicing fog seal material was developed.Through orthogonal theoretical design and analytic hierarchy process,a comprehensive performance evaluation was carried out to determine the optimal amount of tackifier and hydrophobic agent.Performance tests were conducted to evaluate road performance and deicing performance of the material,with the optimal amount of deicing agent being determined.The results show that compared to emulsified asphalt substrate,the cohesion and hydrophobicity of the high viscosity and hydrophobic fog seal materialobtained at the optimal ratio has been increased by 55.7％and 144.3％respectively.When the dosage of deicing agent is 9％to 12％,the storage stability of the fog seal material is good.At the spraying amount of 0.06 g/cm2,the curing performance and anti-slip performance of the seal layer are significantly improved,reaching the optimal equilibrium state.The dosage of deicing agent is linearly correlated with electrical conductivity.After multiple immersion cycles,the high viscosity hydrophobic deicing fog seal material exhibits releasesustainability and durability.The anti freezing effect of the fog seal material reaches the best when the deicing agent dosage is 9％.
