To build the best, most durable pavement, designers must have accurate information on the quality of the subgrade the pavement will stand upon. Cone penetrometer testing is a promising method for measuring subgrade strength. ...

This study examines two highway bridges constructed using novel fiber-reinforced polymer (FRP) composite stay-in-place formwork and an FRP grillage reinforcement system. Both bridge superstructures rely on the FRP components ...

A field evaluation of portable non-nuclear density gauges was conducted to determine their effectiveness and practicality for quality control and acceptance of asphalt pavement construction. Three portable non-nuclear gauge ...

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. ...

The purpose of this study is the development of permeability and density acceptance criteria for hot mix asphalt (HMA) pavements in Wisconsin. The work detailed in this report is Phase I of II. Databases from the Pavement ...

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 water-cementitious material ratio (w-cm) is defined as the ratio by mass of free water to cementitious material in a concrete mix. The microwave oven method (AASHTO provisional standard TP23-93) and the nuclear ...

Abstract Soil/pile set-up is time-dependent increase in pile capacity, and can contribute significantly to long-term pile capacity. If it were possible to incorporate the effects of set-up during design, it may be possible ...

The use of the soil stiffness gauge (SSG) and dynamic cone penetrometer (DCP) for earthwork property evaluation is investigated in this study. SSG and DCP survey data of natural earthen materials, industrial by-products, ...

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 ...
