Effects of Physicochemical Factors on Asphalt Aging
A new model for asphalt oxidative aging is presented. The model proposes that the kinetics of low temperature aging in the pavement temperature range is largely governed by physicochemical...

Waste Geotechnics and Geosynthetics
The geotechnology related to waste management focuses around assessing the movement of water and pollutant transport, containment of the pollutant so that it is unable to pollute the underground...

A Microplane Constitutive Model for Soils
A microplane model for the inelastic behavior of soils is presented. The microscopic constitutive equations are defined independentely for a set of microplanes covering all possible orientations,...

Construction Quality Assurance for Geomembranes
The results of and lessons learned from construction quality assurance (CQA) programs on 19 geomembrane liners are presented. The specifications are generally exceeded by comfortable margins...

Time-Dependent Behavior of FRP Lintels
This paper describes an experimental investigation into the short-term and long-term behaviors of two types of T-shaped lintels made of fiber-glass reinforced plastic with polyester or...

High Early Strength Concrete Containing Large Quantities of Fly Ash
This paper presents results of research performed at a precast/prestressed concrete plant to identify optimum mix proportions for production of high early strength concrete with high fly...

Notch Sensitivity of Ice
Few investigators have examined closely the fracture toughness of macrocrystalline and seeded columnar freshwater ice. There has been a wide scatter in the toughness values obtained even...

Accurate Computation of Freezing Index
'Freezing index' (cumulative degree-days below freezing) is used for predicting frost penetration depths and modelling pavement performance. Contour maps which illustrate geographic trends...

Theoretical Prediction of Temperature Distributions in Airfield Runway Pavements Due to Aircraft Operation
The determination of this transient temperature distribution is important in predicting the thermal effects on pavements due to aircraft operation. In this research, heat exchange at the...
