· The recycled crushed concrete aggregates collected from kerb and channel replacement works (KCRCA—kerb and channelrecycled concrete aggregate) and from the Hervey Range Landfill (HRLRCA—Hervey Range Landfillrecycled concrete aggregate) were assessed based on their physical and strength properties as specified by the Queensland Department of Transport and Main Roads (DTMR) for pavement ...
This paper presents a recent study at the Hong Kong Polytechnic University on the investigation of blending recycled concrete aggregate and crushed clay brick as aggregates in the production of paving blocks. The results indied that the incorporation of crushed clay brick reduced the density, compressive strength and tensile strength of the ...

AASHTO Pavement Thickness Design Guide When designing pavement thickness for flexible and rigid pavements, the following considerations should be used. 1. Performance criteria (serviceability indexes). Condition of pavements are rated with a present
· RECYCLED ASPHALT PAVEMENT AND CRUSHED CONCRETE BACKFILL: STATEOFTHEART REVIEW AND MATERIAL CHARACTERIZATION. This report describes research results from the first year of a threeyear study focused on the use of recycled asphalt pavement (RAP) and crushed concrete (CC) as backfill for mechanically stabilized earth (MSE) walls.
· US History of Using Crushed Concrete for Roadway and Driveway Construction. Since the 1940s, recycling concrete pavements (crushed concrete) has been a fairly common solution. The first instance in the US was following World War II. US Route 66 in Illinois needed to be expanded from two to four lanes. During this reconstruction project, the old ...
cement ratio in crushed bricks concrete increases the compressive strength. The aim of this work is to investigate the effect of the partial replacement of natural coarse aggregate with crushed bricks coarse aggregate in roller compacted concrete pavement. Environmental constrains of quarrying natural aggregates, such as noise, dust, vibrations,
Aggregate" is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete).
Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.
· Base for new asphalt paving: Through a process called rubblization, old concrete pavement can be broken in place and used as a base layer for asphalt pavement laid over it. Bed foundation material for trenches containing underground utility lines: Utility trenches are oven covered with gravel to assist drainage, and crushed concrete makes a good, inexpensive substitute for gravel.
Type 1 compliant Crushed Concrete image from MSH Paving There are aggregates supplied as Type 1 which are a mix or blend of Primary and Secondary materials, or a mix of two different secondary materials (Crushed concrete with crushed asphalt/blacktop being popular in SE England, largely due to the scarcity in that region and aggressive taxation of suitable primary aggregates)
PAVEMENT DESIGN Subbase Effects The current Design does not model the contribution of bases accurately. At the AASHO Road Test, it was found that the concrete pavements with granular bases could carry about 30% more traffic. The current design procedures allows concrete pavements built with granular bases to carry about 5 8% more traffic.

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
