Simulation of delay variation at uncontrolled intersections for mixed traffic conditions
Abstract: Mixed traffic is composed of different vehicle types with varying geometric and acceleration characteristics. Capacity and delay are the two parameters mainly used to measure the effectiveness of uncontrolled intersections. The variation in the lengths and widths of a vehicle type also has an effect on the capacity and delay. Three intersections and three vehicle types are considered for the study. Also, different vehicle compositions scenarios (C1 to C11) were …

An Investigation into the Mechanical and Strength Properties of Rubberized Asphalt Concrete
Abstract: In this study, the suitability of large rubber chunks from shredded tires as aggregates in cold mixes for road construction is investigated. The rubber was used as an additive to the asphalt binder. Thirty percent of rubber by weight was introduced into the binder at a higher temperature and the rubber was allowed to react with the binder. It was shown among other findings that for various particle sizes, the …

Influence of Compaction Technique on Shear Strength of Modified Subgrade Soil
Abstract: The subgrade soil is considered as the foundation for the roadway structure, it is responsible to provide the required stability for the overlaying pavement layers and to limit the deformation due to traffic load repetitions by furnishing homogeneous stress distribution. For poor soil condition, grid reinforcement or Asphalt stabilization techniques are usually implemented to control the deformation and improve shear strength of poor granular subgrade soil. In this work, the …

Studying the Effect of Crumb Rubber Inclusion in the Mix Design Properties of HMA Pavement: A Case Study of Light Traffic
Abstract: Improving the performance of flexible road pavement has been one of the major concerns in highway engineering; these are due to the twin problems of temperature and oxidation that were observed to impede its performance during use. One the fundamental aim of this study is to explore the techniques of crumb rubber inclusion (in 0%, 5%, 10%, 15%, 20% and 25%), these severs as modifier to the mix design properties …

Evaluating the Rate of Response on Asphalt Concrete Mix Permeability Influenced by Non-Bituminous Modifier on Light Traffic
Abstract: Characterization of material property is fundamental in the Mechanistic-Empirical design of flexible pavement. One such key material property is the stiffness of the pavement these influences tensile strain levels and is imperative for either the determination or pavement cracking synonymous with pavement life. It is on this basis, that the present study explored techniques that will improve the performance of flexible road pavement by modifying its stiffness; dynamic modulus, E* …
