the recycled concrete And shall identify location from where concrete will be removed; recycled concrete shall be placed in max 4-in lifts and each lift shall be compacted by a min of 3 passes w/ 10-ton roller () New Jersey Used as Dense-graded aggregate conforms with gradation and plasticity requirements ().
subgrade design Concrete has a modulus of elasticity of 4 to 6 million psi and thus has a high degree of rigidity Also, concrete for paving has substantial beam strength as indicated by its 28-day flexural strengths ranging from 550 to 750 psi, or even greater values for fast-track.
Michigan State University is looking into the use of recycled plastic in portland cement concrete In this study, recycled high-density polyethylene (HDPE) was used to replace from 20 to 40 percent of fine aggregate by volume (75 to 15 percent by total volume) in a lightweight concrete mix.
Absorption: High absorption is particularly noticeable in crushed fine material (minus 475 mm (No 4 sieve)) derived from air-entrained concrete and ranges between 4 and 8 percent (compared with 2 percent or less for concrete aggregates) (7).
In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicl Subbase is often the main load-bearing layer of the pavementIts role is to spread the load evenly over the subgrade.
Concrete, asphalt and/or dirt is hauled off-site *The subgrade is compacted using recycled concrete as needed The concrete is then formed and poured to the size, shape, and depth of the owner’s specifications Paving has a broom finish and is priced per square foot *New paving sub grade is compacted using existing native soil as needed.
Subgrade, and Backfill Material Page 1 of 8 , means a set of requirements for dense graded recycled concrete material intended for use as bedding, embedment material and trench backfill around underground infrastructure Granular A RAP.
2) Compact the subgrade soil to 95% or more 3) Build a concrete curb with wooden nailer board to attach the synthetic turf to and keep everything in place 4) Install a non-porous liner, or geotextile, on the compacted soil as recommended by your design professional.
RECYCLED CONCRETE USAGE IN AGGREGATE MATERIALS 2 HISTORY Engrossed Substitute House Bill (ESHB) passed the Washington State Legislature in As required in RCW , this report fulfills the implementation reporting requirement to “specify and annually use a minimum of twenty-five percent construction.

Aug 15, How much does crushed concrete cost? On average, the cost of crushed concrete will depend on the type of concrete that is purchased, the market conditions, and where you purchase it Most companies are going to either charge by the yard or by the ton When crushed concrete is charged by the ton, the price can vary anywhere from $6 to $14 per.
The content composition of crushed concrete pavement shall be based on weight as follows :
Aggregate base course (road base) The largest application of recycled concrete aggregate (RCA) is for the aggregate base course in road constructionThis term refers to the center layer of the roadbed A cross-section of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally capped on top by pavement, either concrete or asphalt.
Use this calculator to estimate the quantity of Construction Aggregates needed for your particular job, based on width, length, thickness, and product density.
Recycling of concrete is a relatively simple process It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality See ACI 555 () for more information on processing old concrete into recycled concrete aggregat.
Recycled Road Base Calculator These calculators are designed to give approximate amounts only They will help you determine the quantity you need; however, variations in subgrade, compaction of subgrade, or inaccurate measurements, even a quarter of an inch of depth, can make a difference This product must be placed at 3″ depth MINIMUM.
