Abstract

The objective of this research is to assess the elastic deformations and permanent strains of reclaimed asphalt pavement (RAP) material as a base layer when it is treated or untreated with puzzolanic cement under cyclic loads. A large-scale cyclic plate loading testing (CPLT) device was developed for studying the mechanical characteristics of pavement base layer materials. When the RAP percentage of the mixtures increased, elastic deformations and permanent strains increased, but the opposite is true when the cement percentage increased. It was concluded that 100% RAP material can be used in base layers with 3% cement. The obtained deformation values and strain rates can be used as reasonable default design input values to be used by pavement designers when using RAP as a substitute for natural aggregate base layers.

大型试验箱试验研究再生沥青路面(RAP)基层的力学性能

本研究的目的是评估再生沥青路面(RAP)材料的弹性变形和永久应变，当它被处理或未经再生沥青路面(RAP)的基层在循环荷载下。为研究路面基层材料的力学特性，研制了大型循环平板加载试验装置。随着RAP掺量的增加，混合料的弹性变形和永久应变增大，而水泥掺量的增加则相反。结果表明，100% RAP材料可用于3%水泥的基层。所得的变形值和应变率可作为路面设计者在使用RAP代替天然骨料基层时合理的默认设计输入值。

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
