RESEARCH DESIGN AND METHODSdProspective cohort analysis of data from the ACCORD trial included 2,956 adults aged $55 years with type 2 diabetes and additional cardiovascular risk factors. Cognitive tests (Digit Symbol Substitution Test [DSST], Rey Auditory Verbal Learning Test, Stroop Test, and Mini Mental Status Examination) were conducted at baseline and 20 months. Study outcomes were inciden...

Abstract. Seasonal snowpack is an essential component in the hydrological cycle and plays a significant role supplying water resources to downstream users. Yet snow equivalent (SWE) seasonal snowpacks, its space–time variation, remains highly uncertain, especially over mountainous areas with complex terrain sparse observations, such as High Mountain Asia (HMA). In this work, we assessed spatiot...

Recently, the exhaustion of new aggregates and rising price " raw materials" have caused increasing exploitation "reclaimed asphalt pavement "(RAP) in construction rehabilitation. It is being reported that usage RAP does not only reduce cost projects due to less consumption aggregate but also saves land resources greatly protects environment, Where same materials used original highway system ca...

The Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction , operation, management and economic efficiency of the Indiana transportation infrastructure. NOTICE The contents of this report reflect the views of ...

Based in the Department of Wood Science and Forest Products of Virginia Polytechnic Institute and State University, Philip A. Araman is Research Project Leader for the Southeastern Experiment Station, U.S. Forest Service. He first presented this data during last year’s HMA Production University in Madison, Wis. The results are based on a cooperative research study with Earl Kline, Ph. D., assis...

The wheel tracking test (WTT) has been extensively used for laboratory characterization of permanent deformation hot mix asphalt (HMA). However, the fully-confined setup device is unable to capture tertiary zone where shear takes place. This makes resistance characteristics HMA difficult analyze. Hence, a modified tracker (MWT), with unconfined lateral sides along direction was utilized in this...

Abstract. Road conditions are frequently subjected to damage that outlasts the road's design life. One of these is due material's mechanical capability, which insufficient withstand traffic loads and weather conditions. The incorporation plastic tire waste into Hot Mix Asphalt one efforts improve quality (HMA). In addition reducing asphalt concentration in mixture, percentage debris reduces env...
