Method for quickly detecting water content of emulsified asphalt cold-recycling mixture

Abstract

The invention relates to a method for quickly detecting the water content of an emulsified asphalt cold-recycling mixture. The method comprises the following steps: (1) mixing an emulsified asphalt cold-recycling mixture sample according to the target mixture proportion design, or taking a sample from a production field; (2) weighting to obtain the mass of a beaker; (3) weighting to obtain the total mass of the beaker and a mixture; and (4) pouring out the emulsified asphalt cold-recycling mixture, weighting to obtain the total mass of the beaker, and emulsified asphalt, water, fine aggregates and the like adhered to the beaker, calculating a standard adherence rate P and an actual adherence rate P' of different external water blending quantities, and drawing a standard curve as an adjustment reference by taking the external water blending quantities as a horizontal ordinate and taking the adherence rates as a vertical coordinate. According to the method, test data is accurate and reliable, a test process is simple and quick, the water content can be monitored in real time during production of the emulsified asphalt cold-recycling mixture, the external water blending quantities are regulated, a wrapping effect of the emulsified asphalt and a compaction effect of the mixture are ensured, and an effective method is provided for production quality control over the emulsified asphalt cold-recycling mixture.

Description

technical field [0001] The invention is a method for quickly detecting the water content of emulsified asphalt cold recycled mixture, especially a method that can easily solve the problem that the water content of emulsified asphalt cold recycled mixture is slow to detect and cannot guide the production of the mixture in real time. It belongs to highway Technical field of asphalt pavement regeneration. Background technique [0002] In the 21st century, with the rapid development of my country's economy, road transportation is playing an increasingly important role, and a large number of early road surfaces need maintenance and major and medium repairs. According to the design period of asphalt pavement of 8 to 15 years, from now on, about 10% of the asphalt pavement will be repaired, overhauled or rebuilt every year, and the old asphalt mixture produced every year will reach millions of tons. The recycling of old asphalt mixture can save hundreds of millions of RMB in mater...
