A Review on The Exploration of Nanomaterials Application in Pavement Engineering

Abstract

In order to improve the performance of asphalt mixture, the virgin asphalt binder needs to be modified with suitable modifiers. There are various types of modifiers available in market and it is clearly stated and established in most of pavement standard specification. Nowadays, pavement technologist and researchers had put their interests on nanotechnology and they had found that polymeric nanocomposites have shown its effectiveness through the modification of virgin asphalt binder with certain portion of nanomaterials. In addition, many studies have demonstrated that nanomaterials have significant effects in improving the engineering properties of asphalt binder and mixture. Therefore, a thorough literature review on the current research of nanomaterials in pavement engineering for the past decades can enhance understanding and guaranteed something beneficial findings in the future. This paper described the theory of nanotechnology and its historical development including the method used among researchers in evaluation the structural and morphological characteristics of modified binder with nanoparticles. Also, the effect of different types of nanoparticles, suitable dosages, modifying procedures, problems and benefits on asphalt binder and mixture were explained. It is expected that in future the implementations of nanotechnology would have major impacts for better pavement performance.

Laboratory evaluation on the characteristics and pollutant emissions of nanoclay and chemical warm mix asphalt modified binders

“…In principle, WMA technology could reduce asphalt binder viscosity, which allows the asphalt binder to achieve optimal viscosity for coating with the aggregate. This ensures that the mixing and compaction processes could be done at lower temperatures without adversely affecting its performance when compared to conventional hot-mix asphalt (HMA) [1][2][3][4][5]. Blankendaal et al [6] reported that, by using the life http://dx.doi.org/10.1016/j.conbuildmat.2016.03.068 0950-0618/Ó 2016 Elsevier Ltd. All rights reserved.…”

Review of the use of nanomaterials in soils for construction of roads

“…Nano materials are distinguished by having a size smaller than 100 nm in diameter, developed by methods of synthesis of materials in gaseous, liquid or solid state, which are generally sought to have a morphology, chemical composition, microstructures and purity desired for the application of different technologies in the field of chemistry, biomedical, electronics and others [16], [17]. Table I shows the different types of structures that can be achieved in the field of nano materials and their fabrication methods that are currently under development, which initially have a high cost due to the fabrication equipment, but are compensated throughout the life span of the works [18].…”

Resilient Modulus Behavior and Prediction Models of Unbound Permeable Aggregate Base Materials Derived from Tunneling Rock Wastes

“…In order to mitigate flooding risks and related damages, the initiative of sponge cities has been widely enforced, where the construction of permeable pavements has emerged as one of the effective alternatives to enhance drainage capacity of urban road networks [ 4 , 5 , 6 ]. As compared to traditional impervious or low-permeability pavement structures constructed with dense-graded materials, permeable pavement layers constructed with open-graded materials feature larger porosity and better-connected pore structure, as well as the resulting advantages of improved drainability, skid resistance, and sound-absorbing and noise-reducing abilities [ 7 , 8 , 9 , 10 , 11 ]. As tunneling rock wastes (TRWs) are being increasingly produced and stockpiled, the sustainable recycling and reuse of such open- or gap-graded waste materials in permeable pavement construction becomes a major socioenvironmental concern and thus deserves in-depth research efforts.…”
