Laboratory Evaluation of Recycled Concrete as Aggregate in New Concrete Pavements
The Washington State Department of Transportation (WSDOT) has initiated a research project to investigate the use of recycled concrete as aggregates (RCA) in Portland (hydraulic) cement concrete pavements (PCCP). The planned source for the RCA in the project will be from demolished pavements in western Washington, which ...
Optimizing Asphalt Pavement Performance for Climate Zones Within Washington State
Asphalt pavement performance in Washington State varies greatly across the different climatic zones found within the state. The average surface life of pavements west of the Cascades is 16.7 years, compared to 10.9 years for pavements east of the Cascades and as low as 5 years in mountain pass areas. Currently, Washington ...
