Slide1: Tips on using Asphalt Millings For Driveways and parking lots Slide2: Re-cycled Millings have become a popular economical alternative to hot mix asphalt and concrete. However, getting a smooth non-erodible, smooth non-raveling, non-tracking surface has been a challenge. Slide3: Starting with good quality milled asphalt that has been screened provides a more uniform material to spread and compact. Millings from newer roadways are preferred over old dried out millings. Slide4: These rough unscreened millings will not spread out smooth, and will be very difficult to work with as a finish layer. They would work well for less expensive “fill material to build a base” for your project. Slide5: Coarse non screened millings will not compact evenly, large pieces and fines will separate. Large aggregate will continue to grind the fines loose and make them prone to washing and tracking. They will not provide that asphalt paved look that property owners are looking for. Slide6: Another advantage or asphalt millings is they can be stockpiled and worked with as time permits. There is no urgency of getting them spread or laid as with hot asphalt or concrete. Slide7: We recommend 3 to 5 inches of screened Re-cycled Millings spread over a good solid well drained base. Slide8: A good driver and dump and spread the millings in the desired depth you want reducing the time and expense in grading and leveling the millings. Slide9: Millings can be spread directly with dump trucks for large projects such as parking lots, reducing construction time and expense. Slide10: No specialized or large equipment is needed to place and level millings for your project. Slide11: The disadvantage of Raw Millings is they tend to ravel, the “fines” tend to track into vehicles and buildings and can stain surfaces. Millings are also subject to erosion from heavy rain causing ruts and ditching. Slide12: This photo shows the most common disadvantage of using millings which is erosion from heavy rains on steeper roadways and drives. Notice the ditching which in some places is as much as 6 inches deep. Slide13: Property owners have tried everything from applying waste oil, diesel fuel, and burning the millings to get a non tracking and non-eroding surface with dismal results. Slide14: Some suggest pouring diesel fuel on the millings and setting the millings on fire burning them to create heat to make the asphalt sticky. Slide15: This actually reduces the asphalt in the millings which is needed to bond the aggregate together. Also the heat rises and does not actually warm the asphalt. Slide16: Adding Oil, gasoline, and diesel fuel to millings actually breaks down the molecular structure of asphalt and also causes deterioration which allows moisture to enter the surface setting it up for further failure from freeze thaw cycles. Slide17: We all have seen how oil drippings damage asphalt and create pocks and holes in asphalt at convenience stores and on streets where engine oil drips onto the asphalt pavement. Slide18: So what is the solution to re-juvenate the asphalt in the millings to bond the aggregate in the millings into a strong durable smooth surface with that new asphalt look that property owners want. Slide19: Hawk Seale- E Blend Non Hazardous Safe for the environment, doesn’t kill grass or shrubs, birds, animals or insects. Contains a proprietary blend of acid, co-polymers and binder that rejuvenates the asphalt and re-binds the aggregate in the millings. Incorporating Hawk Seale Millings Blend will create a tight durable water proof surface and reduces raveling, erosion and tracking. Slide20: Hawk Seale-E Blend Developed as an Asphalt Preservative The first treated asphalt streets were treated in 1998 and still show no cracking or deterioration. . The first “Millings” roadway constructed with Hawk Seale was in Montana in 2002 as an entrance road into a light Industrial site. The road has required no maintenance to date. In fact Hawk Seale E Blend streets thrive on traffic. Slide21: Once the millings are graded and leveled We recommend 1 gal. of Hawk Seale blend solution be incorporated into the top 3 inches of the millings for maximum strength and durability. Slide22: Property owners in Michigan re-graded this street and then applied Hawk Seale E Blend. This is the before photo of their street project that has required serious maintenance over the years along with a lot of tolerance of the washing and ditching. Slide23: This is a photo of the simple sprayer setup they constructed to apply Hawk Seale E Blend. It consists of a 2” water trash pump, a boom constructed of 2” PVC , 80-50 Fan Jet nozzles 12 inches apart mounted in PVC adaptors for ½” thread and mounted 18 inches off the ground. Slide24: The 12 inch nozzle spacing worked out perfectly. Here the Hawk Seale Blend solution is being surface applied. We recommend 3 passes to allow the solution to soak the millings from the bottom up. Slide25: When applying Hawk Seale E Blend to previously compacted or driven on millings, we recommend re-compacting the millings. Slide26: We recommend compacting the millings 3 to 4 times in the first 24 hours. Compaction can be done with a roller or heavier smooth tired vehicle as well Slide27: This is the finished street after applying Hawk Seale Millings Blend and re-compacting the millings. Slide28: Ideally, we recommend 1 gal. of Hawk Seale blend solution be incorporated into the top 3 inches of the millings. A disk or heavy drag or similar equipment can be used for incorporating the solution. Slide29: Hawk Seale-E Blend will re-juvenate and soften the asphalt in the millings while co-polymers and binder help re-bond the millings to create a smooth, durable water resistant surface. Slide30: Allow the treated millings sufficient time to set up before beginning compaction to prevent running and rippling. Slide31: Millings can be compacted with a steel or rubber tired roller or heavy rubber tired vehicle with smooth tires. Smooth rollers provide a smoother surface and better finished look. Slide32: Hawk Seale-Blend softens the asphalt in the millings which enhances bonding. You will notice a cushioned feel as you walk on the freshly treated and compacted millings. Slide33: This cushioned feel will disappear as the millings cure and harden into a durable surface in about 10 to 14 days. Colder temps may add anther week to fully curing. Light traffic can begin immediately. Slide34: During the curing stage you will want to avoid heavy traffic, heavy farm tractors and aggressive 4 wheelers, also avoid extended parking until millings have fully cured. Divot from a parked truck overnight Note- rain puddle due to water proofing of Hawk Seale Slide35: Here is a photo of a newly constructed millings road. The millings were placed over 4 inches of compacted 2 inch rock for a base and treated with 1 gal per square yard of Hawk Seale E Blend and then compacted. Slide36: Hawk Seale Products do not require hi-tech equipment. Pumps and Tanks can be mounted on trucks or trailers. Sprinkle cans can be used for small projects.
