Pavements always play a predominant role in transportation. Health monitoring of pavements is becoming more and more significant, as frequently suffering from cracks, rutting, and slippage renders them prematurely out of service. Effective and reliable sensing elements are thus in high demand to make prognosis on the mechanical properties and occurrence of damage to pavements. Therefore, in thi...

Enhancing Green Paving in Oklahoma Using Recycled Asphalt Shingles Prof. Musharraf Zaman School of Civil Engineering and Environmental Science Each year, an estimated 11 million tons of old asphalt shingles from roofs are disposed of in the United States. In Oklahoma, it costs between $50 and $150 per ton, depending on size and kind of debris, to dispose of these materials in landfills. Recent ...

The mating behaviour of red deer stags, Cervus elaphus, has been extensively described as harem defence. However, it appears that territoriality may be chosen as a mating strategy when certain conditions are met. In a study area in southwestern Spain, early on in the rut, about 58% of adult males established territories in preferred areas, defended the territory against other males even in the ...

One of the most severe problems with flexible asphalt pavements is permanent deformation in form rutting. Accordingly, practice adding fiber elements to mix improve performance under dynamic loading has grown significantly order prevent rutting distress and ensure a safe long-lasting road surface. This paper explores effects combination ceramic (CF), low-cost, easily available mineral fiber, th...

Pavement maintenance and repair is a crucial part of pavement management systems. Accurate reliable performance prediction the prerequisite for making reasonable decisions selecting suitable schemes. Rutting deformation, as one most common forms asphalt failures, key index evaluating performance. To ensure accuracy commonly used models, input parameters models need to be understood, coefficient...
