Optimizing the Texturing Parameters of Concrete Pavement ...
Curved texturing is an effective technique to improve the skid-resistance performance of concrete pavements, which relies on the suitable combination of the groove parameters. This study aims to optimize these parameters with the consideration of skid-resistance performance and driving stability. A pressure film was adopted to obtain the contact stress distribution at the tire–pavement ...

RECYCLED CONCRETE - Portland Cement Association
140 million tons of concrete are recycled each year in the U.S. alone. Typically, recycled concrete aggregate (RCA) is used as granular fi ll, base and sub-base material, or as aggregate in new concrete pavement. Why do it? Reusing concrete pavement minimizes the amount of raw materials required for a new pavement structure.

What are Dowel Bars? its 4 Placement Steps, and Advantages
In general dowel bars are used in the concrete pavements and are round steel bars. To transfer the load of producing in the concrete slab or pavement, dowel bars are left to joint any slab, column, and pavement. The range of dowel bar length will be 45d to 50d as d is the dia of the bar.

Embedding metal letters into concrete. A how-to article
Embedding stud mounted letters into the concrete does definitely help to maintain stability. Without the studs penetrating the concrete, the letters would soon come loose and disappear. A better way, although far more costly, would be to embed the letters using a stabilizer plate (above). For outdoor applications, stainless steel would be the ...

CRSI: Sustainability
The primary raw materials used to make concrete are abundant in most areas of the world. The cement, aggregates, and reinforcing steel used to make concrete are usually obtained or extracted from sources within 300 miles of the ready-mix, precast concrete, or masonry plant. Most ready-mixed plants are well within 100 miles of the project site.
