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

Abstract

The invention discloses a measuring instrument for the upper limit moisture content of emulsified asphalt cold recycled mixture, a measuring method and an optimum moisture content measuring method. The measuring instrument comprises a base, an end baffle, a ramp plate and a A rolling test tube; the end baffle includes a front baffle and a rear baffle respectively located at both ends of the base, and the ramp plate is inclined between the front baffle and the rear baffle; the test tube includes A cylinder and a cylinder cover arranged at the end of the cylinder; the cylinder is a through cylinder, and the cylinder cover is detachably connected to both ends of the cylinder. The measuring instrument has simple structure, convenient operation and reliable test results. The optimal water content determination method can better solve the problem of water content mix ratio design of emulsified asphalt cold recycled mixture, and promote the popularization and application of 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 Recycling 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 pract...
