Behavior characteristics of Light-Weight Pavement Using Centrifuge Test

Prediction of National Airport Pavement Test Facility Pavement Layer Moduli from Heavy Weight Deflectometer Test Data Using Artificial Neural Networks

The National Airport Pavement Test Facility (NAPTF) was constructed to generate full-scale testing data to investigate the performance of airport pavements subjected to complex gear loading configurations of new generation aircraft. During the first test program, the NAPTF test sections were simultaneously subjected to Boeing 777 trafficking in one lane and Boeing 747 trafficking in another lan...

Uplifting Behavior of Shallow Buried Pipe in Liquefiable Soil by Dynamic Centrifuge Test

Underground pipelines are widely applied in the so-called lifeline engineerings. It shows according to seismic surveys that the damage from soil liquefaction to underground pipelines was the most serious, whose failures were mainly in the form of pipeline uplifting. In the present study, dynamic centrifuge model tests were conducted to study the uplifting behaviors of shallow-buried pipeline su...

Flexible Pavement Test Sections for Studying Pavement Design

It is a well-recognized fact that our pavement design procedures are inadequate in general and seriously lacking in many particulars. The fact that this statement can be applied on a county, state or national basis is little consolation to those in Indiana who must design and build pavements, for ever-changing traffic conditions, in such mileage and at such unit costs compared to the funds avai...

Measuring and Analyzing Pavement Texture Concrete Pavement Surface Characteristics Program

Introduction Pavement texture is defined by the irregularities on a pavement surface that deviate from an ideal, perfectly flat surface. As shown in Figure 1, the World Road Association (PIARC) has established standard categories of texture, classified by wavelength. These categories include microtexture (wavelengths up to 0.5 mm), macrotexture (0.5 to 50 mm), megatexture (50 to 500 mm), and ro...
