The soils were mixed with RBI Grade-81 content of 1%, 2%, 3% and 4% and fibre content of 0.25%, 0.50%, 0.75% and 1.0% of dry mass of soil for determining their individual and combined effect on different geotechnical properties. Additionally, X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) tests were also carried out to know the mineralogy and micro-structure of the hydrated products formed during the stabilization. Leachate obtained from the stabilized soils was tested for concentration of heavy metals and were found well within limits prescribed by the United States Environmental Protection Agency for hazardous waste. The results indicated that the mechanical strength parameters of the soils had significantly enhanced with the use of RBI Grade-81 and polyester fibre which was corroborated by XRD and SEM results. The clay showed higher improvement in its mechanical behaviour than that of sand. The inclusion of fibre changed the RBI Grade-81 treated soil's brittle behaviour into ductile behaviour. The results obtained were indicative of the safe and environment-friendly use of RBI Grade-81 and polyester fibre for use in road construction.

This study presents a comparison of the physical attributes of RAP and natural aggregate, with a focus on their potential use as base and subbase materials in flexible pavements. The physical attributes of RAP and natural aggregate were evaluated using standard laboratory tests, including particle size distribution, specific gravity, water absorption, impact value test, Los Angles Abrasion test, flakiness and elongation test. The research concluded that RAP is comparable to natural aggregate in terms of particle size distribution and bulk density but has lower water absorption, impact, and abrasion values. The results shows that RAP is almost 53% more tougher that natural aggregate when tested for Aggregated Impact test and 30% more harder than natural aggregate when compared by Los Angeles abrasion test. Also, heatmap was used to ...

The traffic axle loading may be much heavier than the specified limit in many cases. As a result of which, the existing road network has been subjected to severe deterioration leading to premature failure of the pavements. There is a dire need of developing a meaningful approach towards implementing the maintenance and rehabilitation schemes of the road network. In such a scenario, development of the effective pavement management strategies would furnish useful information to ensure the compatible and cost- effective decisions so as to keep the existing road network intact. The optimum maintenance and rehabilitation strategies applied in this study would be useful in planning pavement maintenance strategies in a scientific manner and ensuring rational utilization of limited maintenance funds. Once this strategy for urban road network is implemented and made operational; this would serve as win...

These problems can now only be solved by providing an efficient traffic control at intersections and that can be achieved by provision of a traffic signal system at intersections for continuous and efficient movement of vehicles through the intersections Chandigarh-the city beautiful-though a modern and well planned city, is also facing the same traffic problems. Here, the present traffic signals are based on the static feed of time without considering the actual available traffic. This leads to a situation where vehicles wait unnecessarily in one of the lanes while the traffic flow is not up to the considerable amount in the other lane. This paper provides the redesigning the existing traffic signals with a new cycle time by conducting an entire day traffic volume studies at the intersection. The traffic field studies were done on the one of the congested intersection of Madhya Marg i.e. Transport Chowk for having the traffic data inputs.

The main concern with the production of HMA is, it requires large amount of energy and also releases enormous amount of emissions into the environment. Increased environmental awareness has led to a development of Warm mix asphalt (WMA) to reduce the high mixing temperatures of regular Hot mix asphalt (HMA). Warm mix asphalt (WMA) is a recent technology used to reduce the mixing and compaction temperatures by adding some additives. Moreover consumption of plastics is increasing day by day. Once used plastic material is generally thrown out as they do not undergo bio decomposition. Hence waste id either land filled or incinerated. Both are not eco-friendly processes as it pollutes the land and the air. In this study Stability-Flow analysis for the various bituminous concrete mixtures prepared with both the techniques that are WMA and HMA is reported and compared. It is found that 5.65 % is the optimum binder content and Marshall Stability is highest at 0.2% of zeolite with 8% replacement of bitumen with LDPE and also WMA fulfills the requirements specified by IRC29-1988.

The study area along the Vidya Path and Vigyan Path in Chandigarh consisting of flexible pavement is selected to develop a Pavement Condition Index so as to assess the maintenance and rehabilitation needs. The PCI method was used as it is a distress based rating which evaluates the comprehensive visual condition of a road by categorizing different distresses and their severity. The mathematical expression for pavement condition index (PCI) provides an index reflecting the surface distresses which are the manifestations of pavement failure. The model for computing PCI is based upon the summation of deducts points for each type of observable distress. The paper involves extensive use of Google Earth Pro Software for drawing elements of Sections on Map and transferring the coordinates of sections to the field using GPS instrument. Surface distress and severity level data is acquired on the PCI inventory by visual field inspection on different sections. The weighted PCI of the different Sample Units along both the sections is calculated and subsequently results can be used for resurfacing/maintenance work on priority basis.

The most common binder used for road surfacing is bitumen obtained from petroleum However; Petroleum is nowadays becoming scarce due to depletion of its source. Even though bitumen is widely used in road construction, there are some drawbacks in bituminous mix like high susceptibility to temperature variation, tendency to crack, lesser effective service life etc. Therefore, bituminous pavements fail to give the expected service life under adverse climatic, environmental and traffic condition. In an attempt to enhance the service life of bituminous surfacing under adverse prevailing conditions, research is going on throughout the world in the area of additives in search of improved, durable and cost effective bituminous binders. The main objective of this study is to evaluate the properties of bituminous mixes that can be made by use of different grading of bitumen like VG10 VG30 VG40 and different grading of aggregate with using of code references.

A survey design was used to realise the research objectives. The sample population was 41 students studying at the University of Fort Hare. The Safe Sex Behaviour Questionnaire (SSBQ) was utilised as the measuring instrument. Snowball sampling was used to select respondents. Data was analysed with the SPSS. The results of the study confirmed that students who have attended HIV/AIDS awareness training engage in significantly lower sexual behaviour than those who have not attended such training. Understanding the value of HIV/AIDS awareness training programmes in reducing risk sexual behaviour have the potential to help practitioners design effective programmes with much emphasis on individual differences, more specifically on culture and religion. The study provides initial evidence on the impact of HIV/AIDS awareness training in reducing HIV/AIDS risk sexual behaviour which is also important in evaluating different risk sexual behaviours displayed by students which further assists in the curbing of the HIV/AIDS prevalence rate in tertiary institutions.

The specified traffic axle load limit is generally disobeyed with higher axle load vehicles plying over them. This results in severe deterioration of road pavements causing to premature failure of the pavements. Hence determining effective pavement management strategies could result in helpful information to enact cost-effective and compatible decisions for an intact road network. The pavement deterioration models may turn out to be effective in assisting highway agencies to predict the economical results of possible investment decisions based on the pavements maintenance and management.

The effectiveness of a material in stabilizing soil for the subgrade layer of pavement is usually assessed by M R estimated from quasi-static tests (California bearing ratio and unconfined compression strength), but these tests are not the accurate representation of repeated traffic loading, and hence the M R must be determined through laboratory cyclic triaxial test. This review examined more than 35 research papers published over the period 1995 to 2019 and identified 15 stabilizers that have been tested for soil stabilization under cyclic triaxial loading. The analysis of these articles highlights three different categories of stabilizers: first, waste materials such as fly ash, cement kiln dust, oil shale ash ground granulated blast furnace slag, dolime, bottom ash and lignin, second, chemical stabilizers such as lime, cement, lignosulfonate, sodium alginate bio-polymer and an ionic soil stabilizer and third, fibres such as polypropylene and lignin. The soils subjected to the test were organic clay and inorganic soils such as clay, sand, gravel containing soil and black cotton soil. The present paper discusses the effect of confining stress, cyclic deviator stress, number of load applications, curing period and dosage of the stabilizer on the M R of the stabilized soils. The analyses of these articles help understand the importance of cyclic triaxial test for proper characterization of stabilized soils for use in pavement construction. The fact that only a limited number of stabilizers for the soil has been studied so far, this review identifies a scope of determining the M R of materials that are potential soil stabilizers for future research.

There is an urgent need for sustainable waste management by developing design methodologies for their utilization in the construction industry. This study focuses on the geotechnical and environmental aspects of utilizing brick kiln dust (a waste product from brick kilns) in stabilizing the subgrade layer of flexible pavements accompanied with a simultaneous reduction in the associated greenhouse gas emissions. In order to achieve wide applicability of this waste, the proposed stabilization was performed on six subgrade soils of varying plasticity, ranging from the clay of intermediate plasticity to sand with an appreciable amount of silt. Soil-brick kiln dust mixes prepared with 10%, 20%, 30% and 40% contents of brick kiln dust were subjected to experimental investigations. Their compaction and strength characteristics were determined by performing Proctor (modified) tests and California bearing ratio (CBR) value respectively. The greenhouse gas emissions were calculated on the basis of standard inventories of carbon coefficients for road construction materials. The results indicated that the CBR, a key strength parameter of soil was significantly improved with the use of brick kiln dust. The improvement in the CBR was directly proportional to the plasticity of soil. The brick kiln dust stabilization significantly reduced the pavement layer thicknesses as also the associated greenhouse gas emissions for all the soils. The results obtained are indicative of the potential use of brick kiln dust in building sustainable and durable pavements with reduced global warming potential.

In order to curb GHG emissions, sustainable construction methods like soil stabilization with waste materials need to be incorporated in practice by engineers. In this study, the subgrade layer of pavement was stabilized with pond ash, a waste material generated from burning of coal in thermal power plants. California bearing ratio and Proctor (modified) tests were carried out to determine the strength and compaction characteristics, respectively. The proposed stabilization enhanced the bearing strength of the subgrades. The improved strength characteristics of the subgrade resulted in the reduced requirement of materials and their transportation, eventually minimizing GHG emissions. For broad applicability, the study was carried out on six different soils of altering plasticity, which is found predominantly in north Ind...

RBI Grade 81 is one such patented soil stabilizer, and this paper aims to review the geotechnical and geo-environmental properties of RBI Grade 81 stabilized soils for use in the construction of sustainable highways. Regarding the stabilized soils, strength parameters (unconfined compressive strength, California bearing ratio and Brazilian tensile strength), compaction parameters (optimum moisture content and maximum dry density), consolidation parameters (void ratio and compression index), fatigue life, plasticity, durability, chemical composition, mineralogical composition and surface morphology through scanning electron microscopy were reviewed. The effects of the dosage of the stabilizer, curing period and time of elapse were also reviewed along with i...
