Asphalt concrete pavements are vulnerable to freeze-thaw cycles. Consecutive cracking and penetration of corrosive agents can expedite the degradation asphalt result in weight loss reduced strength. Fiber reinforcement flexible bituminous bridge cracks limits crack width enhances toughness composite. Furthermore, steel fibers facilitate heating during maintenance repair operations. Electrical r...

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...

Tensile stress develops in concrete when shrinkage deformations and restraints (internal or external) exist. Utilization of appropriate creep or relaxation functions is crucial for assessing stress and the associated cracking potential in concrete, especially at early ages when chemical and physical properties change rapidly. The existing models, developed either from compressive creep tests or...

Background: Traditionally, cool pavements have been designed as reflective, evaporative, etc. Though the reflective reduce pavement surface temperature significantly, they increase glare, thermal burden on pedestrian traffic, and of nearby buildings. In case evaporative pavements, absence water, reduced inertia solar reflection result in a higher temperature. As result, there has pressing need ...

The coefficient of thermal expansion (CTE) of a typical concrete-paving mixtures made with six different types of coarse aggregates, obtained from fifteen different sources in Wisconsin, was determined. These aggregates belonged to the basic class of glacial gravel, quartzite, granite, diabase, basalt, and dolomite. A total of fifteen different concrete mixtures were used in this study. Triplic...
