• Assessment of Pavement Impacts due to Energy Developments in Texas
  Abstract: In recent years, Texas has experienced a boom in energy-related activities, particularly in wind power generation and extraction of oil and natural gas. While energy developments contribute to enhance the state¡¯s ability to produce energy reliably, many short-term and long-term impacts on the state¡¯s transportation infrastructure are not properly documented. Examples include the impact of frequent truckloads on state highway infrastructure such as pavement structures and shoulders, as well as impacts on roadside infrastructure such as driveways and drainage facilities. This paper describes the work to gauge the impact of increased level of energy-related activities on Texas Department of Transportation (TxDOT) pavements based on developing a geodatabase of energy developments in the state, field visits along with data collection, and assessment of remaining life of energy development impacted corridors that have been identified from this study. From this assessment, recommendations on road maintenance and repair were proposed to mitigate the impact of energy developments on Texas pavements.

• Performance of Various Pavement Repairs in Low-Volume Roadways over Expansive Soil
  Abstract: Expansive soil is considered one of the most common causes of pavement distresses. 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 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 plasticity expansive soil and narrow pavement. The study involved visual survey, field and laboratory testing, surface condition/ride data and structural design calculations for three project sites. The study concluded, from 3-14 years of performance records, that geogrid reinforcement, lime-treated subgrade and cement-treated base were found to be effective treatment options for low-volume roadways where high plasticity expansive soil exists.

• Field and Laboratory Evaluation of Winter Season Pavement Patching Materials in Tennessee
  Abstract: Field survey and laboratory tests were conducted to evaluate the performance of four patching materials used in winter season pothole repair in Tennessee. The adhesiveness, cohesion, moisture susceptibility and loaded wheel test were conducted to investigate the bonding, freeze-thaw resistance and rutting resistance of the patching materials. Statistical analysis on the six month field survey showed that edge disintegration and missing patch are the mainly distress of “throw and roll” patching in winter season. Severe freeze condition, high traffic level and vehicle speed accelerated the deterioration of patching. Patchings with lower depth and larger size especially longer longitudinal length deteriorated faster. Both field and adhesiveness test showed that the cold dump mix had high potential to edge disintegration and missing patch, which is probably caused by the insufficient binder content or an excessive stiff binder. One cold bag mix showed high potential to deformation and low strength performance, mainly due to its single size gradation and weak aggregate skeleton. Cohesion test conducted at different temperature and compaction times presented consistent ranking of materials. 25°C and 15 blows were recommended to evaluate the cohesion of materials at moderate temperature. Two cold mixes did not withstand the 60°C water bath in the freeze-thaw cycling due to the high air voids and 25°C was suggested instead. Reduced wheel load is recommended to improve the effectiveness of loaded wheel test for cold patching mixtures.
