Longitudinal joints in Portland Cement Concrete (PCC) pavement slabs require tie (dowel) bars to control joint opening resulting from thermal stresses. Inspections of PCC pavements by the South Dakota Department of Transportation using ground penetrating radar revealed that it is common for tie bars...

 

Fourteen Thin Lift Treatments (TLTs) in Utah's Department of Transportation (UDOT) Region 2 were evaluated over a five-year period in order to assess their performance. Surface distress data was quantified using Pavement Condition Indices (PCIs), and Remaining Service Life (RSL) were estimated following...

 

An evaluation of the ability of the BBR (Bending Beam Rheometer) as a test to determine changes in the low temperature properties of asphalt mixture parameters was conducted, along with the possible implications of adopting this test for low temperature pavement performance. It was found that the creep...

 

To improve the pavement design and construction in Wyoming, the Wyoming Department of Transportation (WYDOT) is adopting the Mechanistic-Empirical Pavement Design Guide (MEPDG). A full implementation of MEPDG requires the characterization of local crushed base materials. In this research, laboratory...

 

To facilitate the implementation of Mechanistic-Empirical Pavement Design Guide in Wyoming, this research investigated the relationships between subgrade resilient modulus (Mr) and the dynamic cone penetration and the standard penetration test results, selected three best subgrade Mr predictive models...

 

An experimental research study was conducted to develop optimized concrete mixtures for jointed plain concrete (JPC) pavements and field evaluation of newly constructed JPC pavement sections along South Dakota highways. Using South Dakota aggregates, different concrete mixtures were assessed for optimum...

 

This study aims to investigate the age-dependent changes in flexural and fracture properties of fiber-reinforced concrete (FRC) used in the design of thin overlay pavements. Four different types of steel or polypropylene macro-fibers with different dimensions and different fiber volume contents (0%...

 

Conventional test methods for roadway compaction cover less than 1% of roadway; whereas, intelligent compaction (IC) offers a method to measure 100% of a roadway. IC offers the ability to increase compaction uniformity of soils and asphalt pavements, which leads to decreased maintenance costs and an...

 

North Dakota currently designs roads based on the AASHTO Design Guide procedure, which is based on the empirical findings of the AASHTO Road Test of the late 1950s. However, limitations of the current empirical approach have prompted AASHTO to move toward the new mechanistically based pavement design...

 

This report responds to the North Dakota legislature's request for a study of the transportation infrastructure needs of all county and township roads in the state. In this report, infrastructure needs are estimated using the most current production forecasts, traffic estimates, and roadway condition...
