This paper addresses the laboratory experiment of performance properties of recycled CRM binders containing artificially aged CRM binders with wax additives.The warm CRM binders were produced using two wax additives (LEADCAP and Sasobit) and then short-term and long-term aged using the rolling thin film oven (RTFO) and pressure aging vessel (PAV) procedures.The recycled CRM binders were aged through the RTFO and PAV procedures.A set of Superpave binder tests were carried out on the binders through the rotational viscometer,the dynamic shear rheometer (DSR),and the bending beam rheometer (BBR).In general,the results of this study indicated that (1) the addition of long-term aged (LTA) CRM binder can significantly increase the viscosity of the recycled CRM binders as expected,(2) the wax additives in recycled CRM binders were still effective to improve the viscosity and rutting properties even after experiencing the aging process,(3) the CRM binders containing wax additives showed the higher rutting resistance compared to the control CRM binders,(4) the recycled CRM binder containing wax additives was found to have less resistance to fatigue and low temperature cracking,(5) wax warm additives into the recycled CRM binders seemed to have a significant role for cracking properties,based upon their substantial amount.

【摘要】我们知道,教学是教师有计划、有目的、有组织的传授知识的活动。因此,教学是教师与学生的双边活动。新课改理念中明确了学生在教学活动中的主体地位,那就是充分的践行以生为本的教学原则。本文围绕如何实现在初中数学教学中践行以生为本的理念,旨在提高教学效果。  【关键词】初中数学;以生为本;教学;认知  【中图分类号】G633.6 【文献标识码】B 【文章编号】2095-3089(2017)36-02
