HeatWurx patching at two locations in San Antonio (open access)

HeatWurx patching at two locations in San Antonio

"This report documents the placing, cost, and performance of the HeatWurx pavement patching process, which uses infrared heating to make the pavement soft enough to mill and scarify so that it can be mixed with a rejuvenator and pavement millings to form a patch that stays bonded to the surrounding material."

Pavement repair strategies for selected distresses in FM roadways (open access)

Pavement repair strategies for selected distresses in FM roadways

"Expansive soil is considered one of the most common causes of pavement distresses in FM roadways. Depending upon the moisture level, expansive soils will experience changes in volume due to moisture fluctuations from seasonal variations. The objective of this research was to evaluate existing repair projects on selected FM roadways. Those roadways experienced failures in the form of fatigue and rutting in the wheel path, and longitudinal (faulted) cracking including edge cracking. The causes of those failures were mainly linked to high PI expansive soil and narrow pavement" (from abstract).

Performance of lap splices in large-scale column specimens affectedby ASR and/or DEF (open access)

Performance of lap splices in large-scale column specimens affectedby ASR and/or DEF

"This research program conducted a large experimental program, which consisted of the design, construction, curing, deterioration, and structural load testing of 16 large-scale column specimens with a critical lap splice region, and then compared and calibrated models developed in the analytical program with the experimental behavior. Specimens were carefully instrumented both internally and externally to monitor the strain behavior of the concrete and reinforcing steel from specimen construction, curing, deterioration, and final structural load testing."
