Non-Destructive Modulus Testing and Performance Evaluation for Asphalt Pavement Reflective Cracking Mitigation Treatments
Four treatments were evaluated to determine their effectiveness in mitigating reflective cracking via non-destructive FWD tests and Surface Wave Method tests to measure layer modulus, along with field pavement performance surveys.
Rubblization and Asphalt Overlay of a 2-Lane Highway under Traffic
The following pictures present a construction phasing and traffic control scenario for concrete pavement rubblization and asphalt overlay of a 2-lane highway constructed under traffic.
Performance Contracting for Construction on the M-115 in Clare County, MI
This report documents the Michigan Department of Transportation's (MDOT) HfL demonstration project, which involved performance contracting for construction (PCfC) on M-115, a two-lane rural highway in Clare County, MI.
"We found Antigo Construction employees to be well qualified, dedicated, and hardworking. Antigo Construction provided the appropriate type of machinery to perform the job in an efficient and effective manner. The equipment was reliable and well maintained which is backed up by the minimal downtime that occurred on the job."
Greg Schnell, Transportation Director, Sheboygan County (Wisconsin)
Structural Characterization of Iowa’s Rubblized PCC Pavements
This paper describes a field study undertaken to investigate the performance of rubblized pavements in Iowa, which includes characterization of the rubblized Portland cement concrete (PCC) layer (layer coefficient and modulus) using a neural networks-based layer moduli backcalculation program. The average rubblized PCC layer coefficient and backcalculated modulus of the rubblized layer in Iowa were found to be 0.19 and 539 MPa (78 ksi), respectively.
