Nagle Paving Company owns and operates two crushing facilities in the area. Nagle Recycling, located in Livonia, MI next to our asphalt plant receives and crushes raw materials into usable products. This facility is capable of crushing existing asphalt into recycled asphalt product (RAP) and existing concrete into aggregate base.
Often recycled aggregate is combined with aggregate when used in new concrete. An example of a mix design using recycled aggregates in a pavement application is shown following table. Click here for table - Example Mix Design for Recycled Concrete Pavements. Sustainability. Recycling concrete provides sustainability several different ways.
Concrete Recycling – Transcor can be contracted to come out to your site to remove various types of concrete materials including roads, interstate pavement, airport runway, pavement, building demolition material, and plant rebuilds or shutdowns. Transcor recycles over 150,000 tons of concrete material annually, which, in turn, is made into ...

Technical Advisory T 5040.37 Use of Recycled Concrete Pavement as Aggregate in Hydraulic-Cement Concrete Pavement. July 3, 2007. What is the purpose and scope of this Technical Advisory? This Technical Advisory issues information on state-of-the-practice and guidance for the use of recycled concrete pavement as aggregate in concrete used for ...
Recycling Ready-Mixed Concrete • Approximately 5% of the 445 million cubic yards of ready mixed concrete produced in the U.S. each year is returned to the concrete plant. • Recycling this material, as with recycling any
Recycled aggregate is produced by crushing concrete, and sometimes asphalt, to reclaim the aggregate. Recycled aggregate can be used for many purposes. The primary market is road base. For information on recycling asphalt pavement into new asphalt pavement. Recycling of concrete is a relatively simple process.
Concrete pavement recycling is an environmentally sustainable choice in terms of energy and other life-cycle impacts. It can reduce the mining, use, and transportation of aggregate, all of which saves energy and reduces emissions. It correspondingly reduces unnecessary consumption of limited landfill or

Recycled crushed concrete, crushed brick, glass fines, Reclaimed Asphalt Pavement (RAP) and crumbed rubber products now commonly supplement traditional aggregate and sand extracted from quarries in pavement construction.
This research aims to evaluate the potential using of recycled asphalt pavement aggregate (RAP), recycled concrete aggregate (RCA) and silica fume (SF) in production of roller compacted concrete (RCC). Thirty RCC mixes were casted in which natural aggregates (NA) were totally replaced by RAP and RCA with (90% and 10%), (80% and 20%), (70% and 30%), (60% and 40%), …
using such recycled aggregate in the concrete course as well. But this latter practice was discontinued by the early 1990s due to mid-slab cracking observed in pavements constructed with such concrete. Using recycled concrete aggregate (RCA) in the base course has continued, how-ever. Newer mechanistic-empirical design methods and perfor-

concrete properties, compressive strength, flexural strength, splitting strength, permeability, and freeze/thaw durability were tested in the lab to evaluate the potential of including tire chips in concrete paving mixes. The testing results indicate tire chips can be used to replace coarse aggregate in concrete pavement mixtures.

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 (304.3.5) New Jersey Used as Dense-graded aggregate conforms with gradation and plasticity requirements (901.08)
The mechanistic design of a concrete block pavement (CBP) can be very complicated and often requires the use of computer programs. This paper presents a new mechanistic-empirical method, which is implemented in a computer program (DesignPave) that calculates base course/sub-base thicknesses for a range of design inputs such as traffic load, interlocking properties, and material stiffness.
Reclaimed Concrete Material Used as Base or Fill. RCM is most often used as aggregate in a base or subbase course. Although it is generally of high enough quality to be used as base material, RCM can also be used for lesser applications like embankment or fill material. Since RCM is a crushed material, the angular aggregates will provide ...
The aim of using finite element analysis method is to predict the behavior of recycled tire products in concrete pavement under truck load. To achieve this goal, two different validations are considered. The first validation is to simulate the experimental test and the second one is to model the moving truck simulation. These two steps are ...
Pavement base applications are the most common uses for recycled concrete aggregate (RCA) produced from concrete pavement slabs (Snyder 2016). The widespread ac-ceptance of RCA in pavement base layer ap-plications is probably because these uses offer some of the greatest environmental benefits at a low cost, while providing the potential

Recycled concrete aggregate (RCA), on the other hand, has been widely accepted in pavement applications. The sustainable solution of blending RAP with RCA was investigated in this research in an attempt to facilitate the usage of this blend as an alternative pavement subbase material.
Recycled aggregate is produced by crushing concrete, and sometimes asphalt, to reclaim the aggregate. Recycled aggregate can be used for many purposes. The primary market is road base. For information on recycling asphalt pavement into new asphalt pavement. See Asphalt Pavement Recycling.
Washington Rock accepts waste products such as topsoil and concrete. The crushed products can be used as gravel, base course, riprap, and new concrete aggregates. Recycled concrete and asphalt from demolished roadways or structures can be reused on roadways and in construction projects. Waste fill must be certified and exceed 200 tons.
construction of recycled concrete as a lower lift in a composite pavement to increase interest in both recycled concrete and composite pavement design. 1.2.2 Low Cost Provisions Composite pavements require two pavers for placement, capacity to potentially produce two types of concrete, and a larger volume of concrete due to the increased thickness.

Recycling of waste concrete in pavement construction not only decreases materials going into landfill, but also reduces the consumption of or natural aggregates. Base and subbase layers are the main structural elements of a pavement. By elevating the traffic loads and spreading the load through the base and subbase, the stresses ...
