This research study was conducted to determine the influence of maximum aggregate size, lift thickness, and aggregate source on the density and permeability of asphalt mixtures designed according to the Superpave criteria. ...

A new method of examining soil stiffness based on the propagation of elastic waves is proposed and compared to traditional resilient modulus tests. A laboratory testing program is undertaken to study the effect of changing ...

An innovative technique for repairing reinforced concrete beams (or slabs) by attaching FRP (fiber reinforced polymer) strengthening strips to the underside of the beam using powder actuated fasteners and mechanical anchors ...

The objective of this research is to develop correlations for estimating the resilient modulus of various Wisconsin subgrade soils from basic soil properties. A laboratory testing program was conducted on common subgrade ...

The primary objective of this study was to assess the effectiveness and relative performance of commercially available concrete bridge deck and crack sealants. A total of thirteen deck sealants and ten crack sealants were ...

This report presents the results of a detailed stress analysis and a field and laboratory test program which investigated the early-age strength gain for selected portland cement concrete (PCC) paving mixtures used in ...

This report describes a comparison of basic laboratory test results with more sophisticated laboratory and in situ tests methods on soils in Southeastern Wisconsin. The generated soils data in the Milwaukee Marquette ...

In this study several asphalt mixtures were produced using four different aggregate sources, different asphalt contents, and different aggregate gradations. Every mixture was compacted using the Superpave gyratory compactor ...

This report presents the findings of a research study conducted to develop modulus-to-temperature relations for Hot Mix Asphalt (HMA) mixtures used in Wisconsin. Surface deflection data gathered from in-place HMA pavements ...

The objectives of this study were to evaluate the relationship between the performance of asphalt pavements in the field and the Tensile Strength Ratio (TSR) values measured in the laboratory on the original asphalt mixtures ...
