Alex Fraser produces a range of quality, NATA-tested aggregate and road base materials ideal for civil construction and commercial development applications such as road and pavement base, pipe bedding, backfilling trenches and walls and drainage.
To put it another way, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost extender that binds with more expensive cement or asphalt to form concrete.
Hot mix asphalt (HMA) is a mixture of various size aggregates and sand held together with liquid asphalt cement. The liquid asphalt is heated to over 300 degrees and mixed with the aggregates at an asphalt plant. The HMA is loaded into trucks and delivered to your driveway.
Aggregates for Concrete . Key points 'Aggregate' is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Lightweight Aggregates. Vermiculite. Glass aggregate . Adding water to the mix sets off a chemical reaction when it comes into contact with the
I found a local gravel yard with recycled materials and was thinking about using this instead of the typical earthbag material. I have successful bonded recycled asphalt and recycled fines and have strengthened them by adding 15% to 30% clay.
Asphalt mixtures used in road pavements are produced with raw materials such as bitumen and aggregates. The bitumen represents a complex combination composed by hydrocarbons having small amounts of structurally analogous heterocyclic species and some heteroatoms like oxygen, sulphur and nitrogen besides small amounts of nickel, iron, vanadium
Asphalt concrete requires the combining of two or more aggregates, having different gradations, to produce an aggregate blend that meets gradation speciﬁcations for a particular asphalt mix.
A warm, rounded, pebbly mix, brown and beige is chunkier than traditional pea gravel, with a slightly deeper tone. Matte in the sunshine and glossy in the rain, it's beautifully natural all summer, adding
If a road turns to impassible mud in the spring, the only practical way to return it to service immediately is to add crushed stone (not gravel) to strengthen it. Stone is worked into the mud until the road is able to support passing loads.

The asphalt cement shows up as a thin line in between the stones and sand. Remember, sand is very small pieces of stone. The stones and sand in blacktop are immune to UV damage from the sun.
Asphalt uses an oil-based substance called bitumen to make sand and crushed rock stick together like glue. After the asphalt is heated to about 300 F, it is transported to the construction site, where construction crews spread and compact it onto the foundation already in place.

Concrete Materials is committed to recycling products that can be reused. We crush concrete rubble for reuse on roads. We crush asphalt rubble to reuse on driveways and in the production of new asphalt.

In most areas of the country, there are two options for the asphalt itself. The difference is the size of the aggregate (gravel filler) used. The most common mix for residential driveways has finer (1/2 in. or smaller) aggregate and thus forms a smoother surface. Coarser (3/4 in. or smaller) aggregate mixes are stronger but have a rougher finish.
(1) add an allowance of 10 percent ground tear-off shingles into an existing SSP that currently allows crushed concrete and asphalt and various other reclaimed materials in Class 1, 2, and 3 AB, and (2) conduct any tests needed to accomplish this.
When roads and buildings are demolished, concrete and asphalt chunks taken from the site can be cleaned, crushed and used as a construction material called aggregate in new projects.
Other sources estimate the cost to install an asphalt driveway to be between $2,300 and $10,300. RELATED Pros Cons Many residential driveway contractors also use recycled asphalt as a base layer before adding the new asphalt on top. Recycled asphalt is also used on parking lots, gravel road rehabilitation and bike paths, according to
Selection of Vegetation. Application of this practice include diversions, dams, temporary sediment basins, temporary road banks, and soil stockpiles. Planning Considerations. 1.
