摘要
围绕公路隧道特殊的环境,针对沥青路面可燃性和高温释放有害气体等问题,本文通过查阅文献、理论分析、试验、等方法,研究隧道沥青混合料温拌阻燃技术,对改善隧道路面施工环境、提高路面阻燃性能有重要的意义。
     Sasobit、Evotherm、Aspha-min三大主流温拌剂产品中,Evotherm的综合性能最优;Evotherm对沥青性能影响不大;模拟沥青水-热老化过程,改进RTFOT试验,得出水剂温拌剂可降低沥青的短期老化;采用Mashall空隙率法、SGC空隙率法、拌合力矩三种方法评价温拌沥青混合料降温幅度,得出SGC空隙率法是E-WMA降温效果的最佳评价方法;
     采用躺滴法和毛细管上升法联合Young-Dupre矩阵方程得出沥青、温拌沥青和矿料表面能及参数,基于表面能理论建立沥青-矿料、温拌沥青-矿料、沥青-水-矿料、温拌沥青-水-矿料四种情况的粘附功模型,通过模型和材料表面能参数计算四种情况的粘附功,得出无水时温拌剂会对沥青与矿料粘附性的影响是不规律的;有水分时温拌剂会降低沥青与矿料粘附性,且有水时温拌沥青-矿料粘附功与WMA水稳定性呈同样的趋势,说明粘附功可作为混合料水稳定性的补充评价指标;
     根据协同增效原理研制的无机复合阻燃剂9#MAA-Ti,提高改性沥青和混合料阻燃性能,降低沥青贮存稳定性,建议尽量减少贮存时间,其他性能满足规范要求;
     通过PH试验得出温拌剂与阻燃剂不发生交互反应,能均匀的分布在沥青当中,温拌剂、阻燃剂使改性沥青的阻燃性能提高,其它各项性能下降,但下降幅度不大,仍满足规范要求;温拌剂阻燃剂提高混合料高温性能、低温性能、阻燃性能,降低水稳定性,但满足规范要求;
     基于分布分型理论分析得出AC矿料级配分形特征只需一个分形维数D就可以表征,且分维值D与温拌阻燃改性沥青混合料体积参数、疲劳性能、动稳定度、低温弯曲应变能有较好的线性相关性,建立的关系模型可以预估温拌阻燃改性沥青混合料路用性能,验证级配的合理性;
     通过检测现场两种方案生产的阻燃改性沥青性能,得出阻燃沥青现场制备最佳方法是与SBS同步改性法,Evotherm温拌剂添加方式为机械自动控制;
     在有效碾压时间30min和最低碾压温度70℃时,采用PaveCool软件计算出不同环境下沥青路面建议摊铺温度,采用试验路实际情况验证其适用性,得出该建议摊铺温度适用于温拌阻燃改性沥青路面施工。
The warm-mixed antiflaming technology of tunnel asphalt mixture was studied by consulting domestic and foreign literatures、theoretical analysis、laboratory tests、the test road paving, etc in this paper. the warm-mixed antiflaming technology was around the special environment of highway tunnel, aiming at some problems such as the asphalt pavement flammability and releasing harmful gas at high temperature. This technology would have an important significance to improve construction environment and flame resistance of the tunnel pavement.
     The comprehensive properties of Evotherm was optimal among three mainstream warm-mixed agent products—Sasobit, Evotherm, Aspha-min. Evotherm had a little impact on the asphalt performance; the liquid warm-mixed agent could be obtained to reduce the short-term aging of asphalt by simulating the water-thermal aging process of asphalt and improving RTFOT test; the three methods, Marshall voidage method, SGC voidage method and the mixing torque, were used to evaluate of the cooling rate of warm-mixed asphalt mixture; the SGC voidage method was the optimal evaluation method of Evotherm warm-mixed asphalt (The abbreviation is E-WMA);
     The surface energy and parameters of asphalt, warm-mixed asphalt and aggregate was obtained by Young-Dupre matrix equation with the lie drop method and capillary rise method.
     The work of adhesion model of four cases—asphalt-mineral aggregate, warm-mixed asphalt-mineral aggregate, asphalt-water-mineral aggregate, warm-mixed asphalt water-mineral aggregate was established based on the surface energy theory; the work of adhesion of the four situations were calculated through the model and the surface energy parameters of material; the warm-mixed agent would cause irregular effects on the adhesion between asphalt and mineral aggregate at no water, but reduce the adhesion between asphalt and mineral aggregate at water; meanwhile the work of adhesion of warm-mixed asphalt and mineral aggregate showed the same trend as water stability of WMA at water, indicating that the work of adhesion was as a complementary evaluation of mixture water stability;
     The r&d inorganic composite flame retardant,9#MAA-Ti, could improve the flame resistance of modified asphalt and mixture, and reduce the storage stability of asphalt according to the synergistic principle; it is suggested that the storage time try to be reduced, and its other performances could meet the requirements of specification;
     The warm-mixed could not occur interact reaction with agent and flame retardants by PH test, and they could be evenly distributed among the asphalt; the warm-mixed agent and flame retardant could improve the flame resistanceof modified asphalt, but make other various properties decline at a small range, still meeting the regulatory requirements;
     The fractal characteristics of AC aggregate gradation only needed a fractal dimension D to characterize based on fractal theory; and the fractal dimension D had a good linear correlation with volume parameters of warm-mixed antiflaming modified asphalt mixture, fatigue performance, dynamic stability and low temperature bending strain energy; the relationship model could be established to estimate the pavement performance of warm-mixed antiflaming modified asphalt mixture, and verify gradation rationality;
     The best method of on-site preparation for the antiflaming modified asphalt was drawn to sync with the way of SBS modified by detecting two site production programs; the addition way of Evotherm warm-mixed agent was mechanical automatic control;
     The PaveCool software was used to calculate the paving temperature recommended of the asphalt pavement under different environmental at30min of effective RCC time and70℃of minimum rolling temperature; the recommended paving temperature was draw to be suitable for the construction of warm-mixed antiflaming modified asphalt pavement via the actual situation of the test road to verify the applicability.
