Road traffic accidents and their implications for management
… and publicity measures rather than the pure highway engineering function which exists at the present time. Saunders, in 'Road Safety Management in a shire county' showed how tactical objectives were set by safety practitioners but concluded that operational resource planning was a vital …

Development of a volumetric strain influence ground improvement prediction model with special reference to impact compaction
Aubrey Berrangé, a South African roads engineer, invented the impact compactor in 1949 with the intention of achieving improved compaction to greater depths than possible with conventional equipment available at the time. The aim of this dissertation is to present a simple prediction model for the …

Development of a New Cold Binder Course Emulsion Asphalt
Hot Mix Asphalt (HMA) is the most commonly used material in the construction of asphalt pavements. Approximately 650 million tonnes of asphalts for road pavements were produced, worldwide, in 2014. However, the HMA industry is responsible for a substantial consumption of energy, the creation of …

HIGH STRENGTH COLD ROLLED ASPHALT SURFACE COURSE MIXTURES
… CRA mixtures for heavily trafficked road and highway surfacing layers by using different waste and by-product materials (normally used as SCM) individually and/or collectively as a replacement for conventional mineral filler. To achieve the above aim, four SCMs have been used which were: Waste …

Soft Soil Stabilisation Using a Novel Blended Cementitious Binder Produced From Waste Fly Ashes
Soil stabilisation is one of the most common techniques used to mitigate the undesirable properties of soft soils such as low compressive strength and high compressibility. Cement is the most commonly used binder for soil improvement applications in the UK and worldwide due to its high strength …

An investigation of cement coating for aggregates in bituminous material
This research was designed to investigate the properties of aggregate with a new cement coating applied, and to test the effect of including this aggregate in a bituminous road mixture. The investigation was divided into three main areas of study. They were, chemical and physical testing of the …

An improved backcalculation method to predict flexible pavement layers moduli and bonding condition between wearing course and base course.
The aim of this research project is to develop an improved backcalculation procedure, for the determination of flexible pavement properties from the Falling Weight Deflectometer (FWD) test results. The conventional backcalculation methods estimate the pavement layer moduli assuming full adhesion …

Highway embankment design in Bangladesh
… is no systematic approach for the design of highway embankments in Bangladesh. To address this issue, this thesis presents a methodology which can be used for the design of embankments in countries with similar conditions to those experienced in Bangladesh. Such conditions include: the large …

Materials considered for pavement and embankment design
Much of the land area of Bangladesh is in the flood plain and constructing durable roads has always proven challenging since the host soils are not generally suitable and there is lack of suitable aggregate. In addition to these challenging conditions, engineers invariable have limited methods of …

Development of models for optimal road maintenance fund allocation : A case of Ghana
The research was aimed at the development of an optimal road fund allocation model for road maintenance to three road agencies in Ghana. The objective was to compare a novel model by multicriteria analysis (MCA) with deterministic outcome and a model based on preferential analysis to determine …

A Methodology to Assess Data Variability and Risk in a Pavement Design System for Bangladesh.
This study aimed to develop a generic methodology to quantify the risk and reliability of pavement and embankment design for Bangladesh considering the variability in design data. The study also aimed to develop a construction quality control procedure to reduce the variability in data. To achieve …

The development of a thermoplastic road marking material standard
Public roads without road markings, especially roads carrying high traffic volumes, would lead to chaos and accidents resulting in injuries and loss of life. The road authorities need to ensure that all signage is well maintained and conforms to the Southern African Development Community Road …

Climate change and road freight safety: impacts and opportunities
This thesis aims to apply recent conceptual frameworks for climate change impact assessment to the road freight sector of Great Britain in order to identify potential future safety issues. The freight sector is a key component of Great Britain’s economy, and one which is particularly vulnerable to …
