A Comparative Study on the Sustainability of Public and Private Road Transportation Systems in an Urban Area: Current and Future Scenarios

Pervious concrete is a unique kind of concrete having a high porosity, utilized for concrete flatwork application that permits water from perception and different sources to go legitimately through. This research study deals the improvement for strength quality and other necessary properties of pervious concrete in order to implement the same in high traffic roads. 0.15%, 0.20% and 0.25% polypropylene fibers were used to determine separate compressive strength qualities. The observed experimental test results indicated that there is direct variation between the compressive strength and percentages of polypropylene fiber. The present study concluded that an additional 35% increase in the compressive strength was observed in pavement as compared to plain pervious concrete.

Compressive Strength Enhancement of Pervious Concrete Using Polymer Fiber

Garg

“…Ordinary Portland cement and fly ash were used as filler material. Fly ash or pulverized fuel ash can easily be obtained from any coal using factories incinerators and chimneys [1,5,27]; it is oven dried and mixed with aggregate thus replacing some amount of cement which reduces the cost of construction and also makes use of the non-biodegradable fly ash. Cement's specific gravity taken in study was 2.6 whereas specific gravity of fly ash was 3.15.…”

“…In this work we have modifiers which were easily available, abundant as waste, hazardous to environment and non-biodegradable in nature [5,[6][7][8], such as plastic, waste oil, rubber, fly ash and glass. Hence this study works on both environment safety [9][10][11][12][13][14][15][16][17][18][19][20] and modification of asphalt properties [21][22][23][24][25][26][27]. This paper studies major properties of the bitumen by performing the laboratory tests with the waste materials collected.…”

2022

The need to modify the conventional type flexible pavement came up because of the rising advancement in the commercial heavy vehicles and day by day increasing vehicle density in the roads. This has led to increase in frequent monitoring and regular maintenance work of the flexible pavements. Present paper primarily focuses on two aspects, firstly to increase the life expectancy of the roads and second to build flexible pavement roads sustainably. The use of various modifiers such as plastic, glass, rubber, waste oil and fly ash in conventional pavements were studied and found to provide a way to reduce the use of asphalt and get desired strength of the pavement as per the design requirements in the present study.

“…The performance and life of an underground structure of pavement relies on soil foundation strength. [1][2][3][4]. The practice of construction and design of pavement require a minimum value of acceptable stiffness which is majorly specified [5].…”

Proper stabilization of foundation and subgrade is one of the major concerns in modern civil engineering projects. Development of modern infrastructure is causing harmful effect on environment by using chemicals. This situation has caused necessity to discover alternative techniques to achieve desired result without harming environment. Present paper studies use of urea formaldehyde raisin on chemical and physical stability of subgrade. Study was conducted by varying contents of urea formaldehyde by 1%, 3% and 5% and strength, ultimate bearing capacity and other relevant soil strength parameters were determined. At the end, cost benefits analysis was also conducted for the current method with respect to alternate subgrade stabilization techniques.
