Preparation and analysis method of basalt fiber transparent mixture

Abstract

The invention discloses a preparation and analysis method of a basalt fiber transparent mixture, and belongs to the field of road engineering. The method comprises the steps: selecting the particle size and proportion of the transparent crystal according to the grading characteristics of the target asphalt mixture, enabling the composition of the transparent crystal to be close to the grading of the asphalt mixture, measuring the skeleton void rate of the transparent crystal, and determining the use amount of the transparent adhesive binder on the basis of the skeleton void rate; mixing the basalt fibers with the mass fraction of 0.3% and transparent crystal stone for 60-90 s at the normal temperature, adding an epoxy resin curing agent for mixing for 60-90 s, finally adding epoxy resin for mixing for 60-90 s, and obtaining a basalt fiber transparent mixture; loading the basalt fiber transparent mixture into a mold to prepare a test piece, compacting by using a rubber hammer, curing at room temperature for 2-4 hours, and performing demolding; slicing the test piece, wherein the thickness is not larger than 8 mm; polishing the surface of the test piece slice through 400-mesh fine sandpaper till the surface is smooth, and finally removing the slurry on the surface of the test piece slice. The method is used for perfecting the quality control of the basalt fiber asphalt mixture and improving the performance stability of the basalt fiber asphalt mixture.

Description

technical field [0001] The invention belongs to the field of road engineering, and in particular relates to a method for preparing and analyzing a fiber transparent mixture for exploring the distribution of basalt fibers in an asphalt mixture. Background technique [0002] How to improve the performance of asphalt mixture and enhance its resistance to traffic load and unfavorable natural environment is a continuous concern in the field of road engineering. As a special additive and stabilizer, fiber can play the role of reinforcement, adsorption, stabilization and viscosity increase in asphalt mixture, thereby improving the resistance of asphalt mixture to high temperature permanent deformation, low temperature cracking, water damage, fatigue cracking, etc. disease capacity. At the same time, compared with other reinforcement methods, the use of fiber stabilizers usually does not require complicated construction procedures and equipment, and has a lower cost. Basalt fiber ...
