Asphalt Millings 5/8"
|
Characteristics
- 5/8" average aggregate size
- contains asphaltic cement that especially bind when hot and compacted
- used as a topping layer over unscreened asphalt millings
- dust free driving surface during dry periods
- material locks together well providing a tightly bound aggregate
- very resistant to erosion, especially after fully compacted
|
Uses
- driveway finish course
- parking surface when no storm system
- golf cart drives
- works very well on sloped surfaces as a final course
|
|
|
Asphalt Millings - Unscreened
|
Characteristics
- aggregates vary from 1/4" to 4 or 5"
- contains asphaltic cement that especially bind when hot and compacted
- used as a base layer under 5/8" asphalt millings
- without a topping layer, surface finishes bumpy
- material locks together well providing a tightly bound aggregate
- very resistant to erosion, especially after fully compacted
|
Uses
- driveway base course
- parking lot base course
- temporary drives
- sloped surface erosion protection
|
|
|
Crushed Concrete - Without Fines
|
Characteristics
- four graded aggregate products vary from under 1" to 6" for "Rip Rap"
- jagged edges provide a good interlocking mechanism
- all gradations provide excellent base material
- larger gradations (rip rap) used to stabilize muck, wet clay and
other unstable sub grade materials
- coarser aggregates are usually topped with finer gradations for driving over
- highly resistant to erosion, especially after fully compacted
|
Uses
- driveway base course
- parking lot base course
- temporary drives
- sloped surface erosion protection
|
|
|
Crushed Stone - without fines
|
Characteristics
- five products range from 3/8" crush to 1-1/2" crush
- the absence of fines allows compaction and percolation
where drainage through the applied layer is needed
- absence of fines provide lower dust levels
- material locks together well providing a tightly bound aggregate
- very resistant to erosion, especially after fully compacted
|
Uses
- driveway base to finish course depending on product selection
- parking surface when no storm system
- golf cart drives
- works very well on sloped surfaces as a final course
|
|
|
Crushed Stone - with fines
|
Characteristics
- aggregates vary from 3/8" to 1-1/2" in three different products
- contains fines to form a well graded compactable material
- is mostly impervious to water
- grades well to form a smooth and uniform surface
- the fines may partially erode in heavy rains on slopes until fully compacted
|
Uses
- driveway base or final course
- parking lot base or final course without a storm system
- temporary and permanent drives
- grades to a very smooth driving surface
|
