Abstract
There are three major types of asphalt surfacing, characterized by a mixture of bitumen and stone aggregate. These are: Dense Graded asphalt (DGA); Stone Mastic Asphalt (SMA) and Open Graded Asphalt (OGA). Asphalt surfacing differ by the proportion of different size aggregate, the amount of bitumen added and the presence of other additives and material. The first aim of this study is to provide an updated systematic review of the evaluation of stone mastic asphalt in construction. This paper entitled “Stone Mastic Asphalt.” aims studying Objectives, construction material composition, economy achieving by using waste materials and advantages over the conventional mixes. Accurate quantification of aggregate gradation is essential for a better understanding of its effect on the load-carrying capacity of an asphalt mixture and Volumetric analysis of the aggregate. study investigates the benefits of stabilizing the stone mastic asphalt (SMA) mixture in flexible pavement with shredded waste plastic and use of baggase in the SMA.

Abstract
“Continuously reinforced concrete pavement” as the title suggests this type of pavement is reinforced throughout in longitudinal direction. This type of pavement has no transverse joints unless and until there is end of pavement or the pavement comes in contact with some other pavement or bridge. A longitudinal joint exists only if the road is wider than 14 feet. Due to reduction of joints smooth and continuous riding is possible resulting in fuel saving. Also CRCP roads are maintenance free if properly constructed and care is taken while placement of steel. Once CRCP roads are constructed they need not to be taken care of for the next 50-60 years. The principal behind this roads is that “Let the road crack”, exactly opposite as in case of other type of roads where we avoid crack formation at any cost. CRCP is allowed to crack due to which stresses in the pavement are released. The cracks formed are held tightly by the reinforcement, due to which widening and deepening of cracks is restricted. Hence we can conclude that in CRCP controlled cracking is permitted. The initial cost of CRCP is high, but as it is maintenance free, and lasts for decades, overall cost of CRCP is less as compared to other type of reinforced concrete pavements. Study and observations have shown that this type of roads are alarmingly successful, hence CRCP is widely used in USA, GERMANY, BRITAN, and several other developed and developing nations. Use of CRCP will enhance the cement, and steel industries; it will reduce the fuel consumption by vehicles, and will save lots of money required for frequent construction and repairs of other type of pavements.

Abstract
To perform travel demand estimation for any city using conventional four step demand modeling, it would involve lot of time and resources. As of now, to understand the travel demand for a particular city using available parameters there are no ready reference models are available. Considering this, an attempt has been made in this paper to model the travel prediction using the readily available parameters. About six models were developed utilizing various parameters such as Population, Average Household Income, Road Network Length and area of the city. The models developed were validated by conducting the households’ surveys in two Cites Durgapur and Gwalior. Among the six models developed, the predicted values based on Population and City area are very close to the observed values of Durgapur and Gwalior cities.

INTRODUCTION
SkyBus is a greener way to travel. When delegates choose to travel on SkyBus between the Airport and the city they all leave a smaller carbon footprint. SkyBus supports Green fleet and plants over 7,000 trees each year to offset carbon emissions from its fleet’s fuel consumption. Sky Bus operates 24 hours/7 days a week- over 250 trips a day moving in excess of two million passengers.

Abstract
The growing population of India has created many problems one of the challenging ones being car parking which we confront almost every day. Besides the problem of space for cars moving on the road, greater is the problem of space for a parked vehicle considering that private vehicles remain parked for most of their time. While residential projects still escape with designated parking, the real problem lie with commercial spaces many a time which is overcome by taking extra open spaces to park.

Multi-level Parking systems for sometime have provided relief since they come with a number of advantages – optimal utilisation of space, lower maintenance and operational cost, lower construction cost, secure and environment-friendly nature, comfortable for the drivers, cost saving for builders by saving height or depth. Multiple Level Car Parking Systems are much in vogue a method of automatically parking and retrieving cars that typically use a system of pallets and lifts and signalling devices for retrieval. They serve advantages like safety, saving of space, time and fuel space but also need to have an extra and a very detailed assessment of the parking required, space availability and traffic flow.
