Effects Of Fiber And Lithium On Mechanical Properties Of Concrete Made Fromrecycled Concrete Aggregate
The growing demand of construction aggregates has raised concern about the availability of natural aggregates. Over two billion tons of natural aggregate are produced each year in the United States and that number is expected to increase to 2.5 billion tons by 2020. This has raised concern about …

Evaluation of lower quality recycled PCCP for Portland Cement Treated Base (PCTB)
With recycled concrete aggregates (RCA) becoming a more popular and cost effective alternative to virgin aggregate, the Kansas Department of Transportation (KDOT) looks to incorporate these aggregates into Portland cement treated base (PCTB). KDOT currently practices a freeze-thaw method that …

Development and Structural Performance Assessment of Low-Carbon Concrete Using Recycled Concrete Aggregates and Secondary Materials
… the structural performance of low carbon concrete (LCC) developed with various proportions of recycled concrete aggregates (RCA) and supplementary cementitious materials (SCMs) as sustainable material alternatives to conventional concrete materials. Extensive materials testing and analysis …

High-volume recycled materials for sustainable transportation infrastructure
… the feasibility of using high performance concrete made with high-volume of recycled materials in transportation infrastructure. The main focus was to develop mixtures for rigid pavement construction. A variety of fine and coarse recycled concrete aggregates (RCA) were investigated. The …

Investigation of Testing Methods to Determine Long-Term Durability of Wisconsin Aggregate Resources Including Natural Materials, Industrial By-Products, and Recycled/Reclaimed Materials
… projects. Being able to select durable aggregates for use in transportation projects is of considerable importance, if the aggregate deteriorates then the constructed facility requires premature repair, rehabilitation or replacement. Realizing the importance and also that deficiencies in …

Investigation on the Overall Performance of Recycled Concrete Affected by Alkali-Silica Reaction
Pressure is mounting in the concrete industry to adopt eco-efficient methods to reduce CO₂ emissions. Portland cement (PC), an essential concrete ingredient, is responsible for over two-thirds of the embodied energy of the concrete, generating about 8% of global greenhouse gas emissions. Extraction …

Properties of functionally graded concrete slabs
… is the one prescribed in ASTM D7313 for asphalt concrete. Several field tests were run to examine the sensitivity of the test relative to the location in a pavement slab (i.e. top of the pavement, bottom of the pavement, etc). It was found that the DCT test could, with statistical confidence, …
