Evaluation of Rutting Susceptibility of Bituminous Mixes Using Finite Element Modeling
Abstract: Pavement performance mainly depends on the quality of bituminous mixes. Poor bituminous mixes cause premature failures such as rutting or permanent deformation, cracking, bleeding etc. The design of bituminous mixes should contain certain criteria to prevent premature failures. The mixes designed based on these criteria are generally known as performance based mix design and are gaining popularity in the recent times. Among various types of pavement failures, permanent deformation or …

Thermal Effects on Elastic and Rigidity Modulus of Flexible Pavement Wearing Course
Abstract: Laboratory investigation of flexible pavement was carried out using asphalt concrete samples to simulate the behaviour of actual field conditions of a flexible pavement. The study was carried out in order to ascertain the changes that will result in the elastic and rigidity (shear) modulus of flexible pavement when subjected to increasing temperature conditions (thermal effect). The study became pertinent because mechanistic design of flexible pavement requires as input 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 …
