Problems solved by technology
[0006] In the determination of the optimum moisture content, most technicians observe the mixing performance and adhesion of the mixture through mixing, and select the moisture content based on past experience, which cannot achieve good results in engineering practice
In addition, in the face of this problem, some inexperienced construction companies have nothing to do, which limits the popularization and application of emulsified asphalt cold recycling technology to a certain extent

The invention discloses a determinator and a determination method for the upper-limit water content of an emulsified asphalt cold-recycled mixture, and a determination method for the optimal water content. The determinator comprises a base, an end head baffle, a ramp plate and a test cylinder capable of rolling on the ramp plate, wherein the end head baffle comprises a front baffle and a rear baffle which are arranged at the two ends of the base respectively, and the ramp plate is slantwise arranged between the front baffle and the rear baffle; the test cylinder comprises a cylinder body and a cylinder cover arranged on the end part of the cylinder body; the cylinder body is a middle-through cylinder body, and the cylinder cover is detachably connected to the both ends of the cylinder body. The determinator is simple in structure, convenient to operate and reliable in test result. The determination method for the optimal water content is used for solving the problem of a matching ratio design for the water content of the emulsified asphalt cold-recycled mixture well, and promoting the popularization and application of the emulsified asphalt cold-recycled mixture.
Description
technical field [0001] The invention relates to the technical field of asphalt, in particular to an upper limit moisture content measuring instrument for emulsified asphalt cold recycled mixture, a measuring method and an optimum moisture content measuring method. Background technique [0002] The cold recycling of emulsified asphalt plant uses mixing equipment to mix recycled asphalt pavement (RAP) with emulsified asphalt, new aggregate, active filler, and water at room temperature to form emulsified asphalt cold recycled mixture, which is paved at room temperature. Asphalt pavement regeneration technology for pavement structural layers. This technology has many advantages such as high recycling rate of old materials, resource saving, environmental protection and energy saving of normal temperature mixing, excellent structural performance and high technical feasibility. Therefore, it has been favored in domestic road overhaul projects in recent years. [0003] Long-term pr...
