Asphaltic concrete for pavement construction in India are produced by using crushed stone, gravels etc. as aggregate. In north-Eastern region of India, there is a scarcity of stone aggregate. Therefore the road engineers are always in search of an optional material as aggregate which can replace the regularly used material. The purpose of this work was to evaluate the utilization of substandard...

The influence of waste cooking oil (WCO) on the performance characteristics of asphaltic materials indigenous to Trinidad, namely, Trinidad Lake Asphalt (TLA), Trinidad Petroleum Bitumen (TPB), and TLA : TPB (50 : 50) blend, was investigated to deduce the applicability of the WCO as a performance enhancer for the base asphalt. The rheological properties of complex modulus (G (∗) ) and phase ang...

Damages such as rising and cracking due to enlargement growth of roots are quite often observed in the components such as path pavements, curbs, retaining walls and garden furniture on green roof. To avoid the defects, root resistance of those components used for green roof should be estimated by a suitable test before actual applications of them. In this study a test apparatus and a test metho...

The workability of asphalt mixtures influences the logistical processes and workmanship during pavement construction. There are various methods for analyzing asphaltic concrete mixtures. However, there is a lack user-friendly laboratory that enable technologists, engineers, technicians, researchers to characterize trend via Newtonian physics. In this paper, new methodology, based on momentum th...

The central purpose of the research is to support the California Department of Transportation (Caltrans) Quieter Pavement Research Program, which has as its goals and objectives the identification of quieter, safer asphalt pavement surfaces. The research conforms with Federal Highway Administration (FHWA) guidance provided to state departments of transportation (DOTs) that conduct tire/pavement...
