Cement concrete pavements are designed for flexural fatigue loading due to traffic. Due to its numerous advantages high performance cement concrete is finding it’s way in pavement construction. This paper investigates the fatigue strength of High Performance Cement Concretes subjected to flexural loading. Fatigue studies are conducted on these concretes to obtain the fatigue lives at various st...

Highways and in particular their pavements are the fundamental components of the road network. They require continuous maintenance since they deteriorate due to changing traffic and environmental conditions. Monitoring methods and efficient pavement management systems are needed for optimizing maintenance operations. Pavement performance prediction models are useful tools for determining the op...

This paper presents a systematic full scale field study on the structural performance of Plastic Cell filled Concrete Block Pavement (PCCBP) for different cell thicknesses subjected to live traffic conditions. Five test sections of various thicknesses viz., 50 mm, 80 mm, 100 mm, 120 mm and 150 mm of PCCBP over 100 mm thick water bound macadam (WBM) sub-base layer has been constructed at the app...

Construction and demolition waste are one of the major streams in world. Aggregates must be used significant quantities during road construction maintenance as base sub-base materials. Government local businesses promoting use recycled material old pavement andconstruction due to high cost virgin aggregates. Concrete, subgrade, railroad ballast materials can all made from concrete aggregate (RC...

Rob or tide water is a flood of seawater rising sea level caused by high inundating land. Heavy traffic and tidal immersion on main roads result in permanent deformation require quality asphalt that resistant to loads. The use combination LDPE aggregate slag an unprecedented update. Polyethylene (PE) plastic waste provides resistance therefore the can be new Job Mix Formula able withstand (rob)...

In Portland Cement Concrete (PCC) pavement of the roads, dowels bar transfers vehicle loading to the unloaded slab. Load Transfer Efficiency (LTE) is used to evaluate dowel bars in PCC pavement. This parameter is defined as the vertical displacement ratio of the loaded slab versus the unloaded slab. In this study, the impact of effective factors (friction coefficient between dowel and concrete ...

Verification of the serviceability limit state of vibrations due to traffic live loads can be neglected in conventional types of concrete road bridges but becomes critical in the design of slender structures like Under-Deck CableStayed bridges. The novelty of the work presented in this article is that an innovative vehicle-bridge interaction model is employed, in which realistic wheel dimension...

Ever-increasing traffic loads, in addition to hot climates, have always been a challenge for both road pavement authorities and engineers. Technically, asphalt binder concrete modifiers that generally increase the viscosity provide higher resistance permanent deformation optimal choice. In this paper, layers of motorway constructed 2015 were studied. pavement, plastomeric polymeric compound syn...
