Traffic has increased on low volume roads due to an increase in the population and commercial development. Population surge led to increase average daily traffic on highways and low volume roads. The average daily traffic increased on low volume roads causes distress and damage to pavement. In order to have a durable low volume road that can bear the traffic surge and the load, agencies such as the Ohio county engineers have implemented and used variety of road treatments such as: (1) Aggregate Overlay (2) crushed reinforced concrete, brick & 411 and surge & 411, (3) Concrete overlay using concrete and fiber cement, (4) Motorpave, (5) Recycled materials including asphalt grinding and 70% asphalt, 30% concrete, (6) Geotextile including fabric reinforced stone and geogrid reinforced stone, and (7) Full depth reclamation with additives such as: FDR-Cement, FDR- Mechanical, FDR- Lime, FDR- Asphalt Treated, FDR- Fly Ash, FDR- Asphalt Grindings, and FDR- Permazine. However, there is a need to evaluate all these treatments to develop a repeatable, low cost methodology to characterize the load carrying capacity of materials used in order to be able to recommend it for future design work. Field and laboratory testing were conducted to evaluate these treatments. In the field, Dynamic cone penetrometer (DCP) and portable seismic property analyzer (PSPA) was conducted on 99 sites that used different types of treatments. The DCP results were analyzed using two methods: AASHTO (1993) Selection 2.3.5 and Roy (2007) method. Values obtained using these two methods were then compared to find the trend of the method when used to characterize the load carrying capacity. Comparing the two DCP analysis methods, AASHTO method was slightly higher than Roy method when comparing to literature values. Moreover, laboratory testing was performed on specimens collected from sites using unconfined compressive strength and the MTS and then the results were compared with the moduli obtained using the PSPA. The results had a high variability among each treatment. Variability may be due to time road constructed, materials type, and moisture. Resilient modulus obtained using seismic data had lower values than laboratory results in most treatments, such as Fiber cement Portland concrete cement and whitetopping. However, it is the opposite with the FDR-cement treatment in which seismic values gave about 9% higher values than the laboratory ones. Layer coefficient was estimated for 85% reliability and 50% and was in an acceptable range comparing layer coefficient obtained from other studies.
