Abstract

The low RAP content, hot mixing conditions, and the addition of a high ratio of new bitumen and aggregates result in low economic and environmental benefits for current regeneration technologies. A bio-rejuvenated additive (BRA) that can fully (100%) regenerate the RAP without heating is proposed in this paper. To reveal the mechanisms of BRA-rejuvenated RAP, the effects of BRA on the chemical structure and molecular weight of the RAP were investigated using Fourier-transform infrared spectroscopy and gel permeation chromatography. The mechanical performance and water damage resistance of BRA-rejuvenated RAP were studied. Low contents of new bitumen or epoxy resin were suggested to increase the mechanical performance of 100% RAP. The results show that the 1.5% BRA-rejuvenated RAP had the best mechanical performance. The blending of BRA with recycled RAP is a completely physical process, without any chemical reactions. The molecular weight of BRA is lower than that of bitumen; it can substantially increase the content of light components in aged bitumen, and play the role of adjusting and restoring the balance of the components of aged bitumen. The mechanical performance of BRA-rejuvenated RAP is enhanced significantly by adding low dosages of new bitumen or epoxy resin.

摘要

低RAP含量、热拌条件以及高比例新沥青和集料的添加，使得当前的再生技术在经济和环境效益方面较低。本文提出了一种无需加热就能完全（100%）再生RAP的生物再生添加剂（BRA）。为揭示BRA再生RAP的机理，采用傅里叶变换红外光谱和凝胶渗透色谱法研究了BRA对RAP化学结构和分子量的影响。研究了BRA再生RAP的力学性能和抗水损害性能。建议采用低含量的新沥青或环氧树脂来提高100%RAP的力学性能。结果表明，1.5% BRA再生RAP具有最佳的力学性能。BRA与再生RAP的掺配是一个完全物理过程，没有任何化学反应。BRA的分子量低于沥青；它能大幅提高老化沥青中轻质组分的含量，并起到调节和恢复老化沥青组分平衡的作用。通过添加低剂量的新沥青或环氧树脂，BRA再生RAP的力学性能显著提高。
