Abstract

The introduction of any new disruptive technology in a traditionally well-established industry, such as the road construction industry, is usually associated with considerable resistance. This is especially relevant when the new technology is based on the use of granular materials traditionally considered to be of an unacceptable quality in combination with relatively new concepts such as New-age (Nano) Modified Emulsions (NME). In such cases, the fact that the material design methods are based on fundamental scientific principles and have been proven in both laboratories and through Accelerated Pavement Testing (APT) may be of little influence. However, the general acceptance of new disruptive technologies, e.g., telecommunications and Information Technologies (IT), have been based on the considerable advantages it presented. The same principles are applicable to the general acceptance and use of the NME stabilisation/enhancement of materials in the road construction industry. This article is aimed at the practical cost-effective demonstration of the general application of the use of nanos-silane-modified emulsions in the construction of the highest order roads, i.e., inter-city multi-lane highways, lower-order roads (including Low-Volume Roads (LVR)), and even local accesses to farms and in villages/townships. The implementation of NME technologies is directly associated with ease of use, time, and cost savings, and with the addressing and reduction of risks applicable to the use thereof.

Highlights

  • The introduction of any new disruptive technology [1] in a traditionally well-established industry, such as the road construction industry, is usually associated with considerable resistance

  • In order to be of benefit and to assist in addressing the considerable backlog in transportation infrastructure in the developing regions of the world, the practical aspects associated with new technologies must be proven to such a degree that all doubts are sufficiently addressed in order to overcome a natural resistance to change

  • Based material design methods based on the mineralogy of granular materials have been developed to ensure that potential risks associated with the introduction of new technologies are minimised, if not eliminated

Summary

Introduction

The introduction of any new disruptive technology [1] in a traditionally well-established industry, such as the road construction industry, is usually associated with considerable resistance. Emulsions (NME) [3]; Test requirements such as XRD scans [4] (relatively old concepts in fields such as geology and mining) to analyse naturally available granular materials [5]; Scientific material design methods including the basic generic fingerprinting of materials mineralogy and scientific principles involved in the identification of materialcompatible nano-modified stabilising agents [6,7]; and Pavement layer bearing capacity tests, which, in a traditional sense, may be foreign to the road construction industry, i.e., Unconfined Compressive Strengths (UCS) [8] and Indirect Tensile Strengths (ITS) [9] Most of these concepts have been in use for many decades, if not more than a century, especially in the built environment [10,11], the traditional road construction industry is notoriously conservative and slow to adapt. This can be accomplished through pre-empting any construction-related concerns and addressing potential problems as well as risks for general acceptance to be achieved
