 Civil Engineering Research Journal- Juniper Publishers Abstract Although there are studies that compared between indirect left-turn treatments such Median U-turn (MUT) or RCUT to the Conventional Intersection (CI) designs, very few have compared between the operational performances of MUT versus RCUT. Furthermore, few studies on the Quadrant Roadway Intersection (QRI) were found in the literature. The main objective of this paper is to assess different designs for the accommodation of left turns through indirect maneuvers. Traffic performance of the proposed intersection designs was evaluated based on microsimulation. The results revealed that the difference between the two designs, RCUT and MUT lies in the amount of traffic rerouted to the crossover intersections. Increasing the traffic downstream of the main intersection to the crossover intersection still has an effect on the main intersection’s operations. Proper design and spacing is needed at the crossover intersection to mitiga

 Civil Engineering Research Journal- Juniper Publishers Introduction As the population increases, more infrastructure and housing facilities needed. To satisfy the need especially in highly dense cities, construction should be performed safely in anywhere, regardless steep-sloped areas, soft-grounds and near the bank of the river or sea-shore. There is no limit to build any structure for urbanization if it is necessary. Reinforcement is an important method for such kind of safe constructability. There are several methods for reinforcement that can be applied to soil itself or can be used with concrete structures. Reinforcement materials such as geosynthetics can supply effective soil improvement when necessary to avoid the failure mechanism. If the resistance of the deformation which is called as “stiffness” of soil is less, reinforced structure (reinforcement+soil) would be the solution. Usually the soil itself doesn’t have enough resistance to keep its form under pressure. Geosynthet

  Civil Engineering Research Journal- Juniper Publishers Abstract Stabilised earth is an alternative construction material which is economically and environmentally beneficial compared to the conventional material such as baked brick and concrete. Earth is used as a construction material in every continent since the earliest civilisation. Existing literature shows that the use of earth as a building material saves cost, time, energy, and reduces environmental pollution. This paper critically reviews the literatures and come up with a generic list of benefits of earth construction. A series of in-depth interviews then investigate and ascertain from the Zimbabwean construction professionals whether stabilised earth construction is beneficial in in urban low-cost housing in Zimbabwe.
