Abstract

A method for evaluating comprehensive performance of tourmaline modified asphalt and optimizing proportion of tourmaline modified asphalt comprises the steps of selecting 16 technical indexes, such asthe penetration index, penetration, equivalent softening point, ductility (10 DEG C), equivalent brittle point, penetration aging ratio, softening point increment, ductility aging ratio, adhesion grade, emission reduction rate, oxygen index, NOx purification rate, HC purification rate, CO2 purification rate, CO removal rate, the material cost, etc., as the evaluation indexes, combining multi-factor test with efficacy coefficient, systematically analyzing the basic properties, environmental efficacy, economic benefit and comprehensive performance of low-carbon modified asphalt, so that the method is strong in practical operability and reliability, avoids the one-sided evaluation, and provides a new idea for the comprehensive performance evaluation of tourmaline modified asphalt.

Description

technical field [0001] The invention belongs to the technical field of performance evaluation of modified asphalt in road engineering, and in particular relates to a comprehensive performance evaluation and ratio optimization method of tourmaline-modified asphalt. Background technique [0002] At present, developing a low-carbon economy and building a low-carbon society have become the strategic priorities of China and the world. With the increase of people's awareness of environmental protection, more requirements have been put forward for the functions of pavement materials. Road materials are not limited to the goals of good road performance and durability. New low-carbon pavement materials have become the main research direction of road researchers. one. Low-carbon environmentally friendly pavement materials specifically refer to environmentally friendly pavement materials with the characteristics of low pollution and low energy consumption, that is, the materials can e...
