乳化沥青混合料初始强度评价方法的研究

Study of initial strength evaluation method of emulsified asphalt mixture

通过修正马歇尔稳定度试验和无侧限抗压强度试验两种试验方法来研究乳化沥青混合料初始强度的评价方法。在马歇尔试验中,对于水泥—乳化沥青混合料采用再修正马歇尔试验方法,并采用正交方法设计试验。试验结果和理论分析表明:采用无侧限抗压强度试验评价乳化沥青混合料初始强度更合理,并提出评价的参考标准;同时表明水泥和矿粉是影响乳化沥青混合料强度的重要因素。

This paper studied initial strength evaluation method of emulsified asphalt mixture wirth corrected marshall stability experiment and unconfined compressive strength experiment. In ini- tial marshall stability experiment, cement emulsified asphalt mixture adopted re corrected marshall experiment method that the author brought forward, and adopted method to design experiment. Ex- periment results and theory analysis showed unconfined compressive strength experiment is more suit able to evaluate initial strength of emulsified asphalt mixture. At the same time, this paper put for word reference standard of evaluation. It also showed that cement and ore power are important factor for technical capability of emulsified asphalt mixture.
