The differences between asphalt and concrete are as different as black and white, literally However, there are some different things that can be done to both asphalt and concrete to get away from the traditional black or off-white colors As a general rule of thumb, concrete is an easier material to work with to get different finish.
An additional resource many may find helpful is NCHRP Synthesis 464: Thin Asphalt Concrete Overlays, which documents the current state of the practice (2014), as well as research efforts on the use of thin asphalt concrete overlays for pavement maintenance, rehabilitation, and preservation.
TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 464: Thin Asphalt Concrete Overlays documents the current state of the practice as well as research efforts on the use of thin asphalt concrete overlays for pavement maintenance, rehabilitation, and preservation.
If the overlay is being placed only to remedy functional deficiencies, normally a thinner overlay would suffice However, two inches is the minimum practical constructible thickness for an overlay Alternately, a thin hot mix asphalt wearing course may be considered.

Oct 30, 2017· What Is Asphalt Overlay? Asphalt overlay, also known as resurfacing, is a feasible and cost-efficient option for repairing minor surface damages to your pavement such as small cracks, rutting, depressions caused by large vehicles, some water damage, potholes, and so on.
Surface Overlay In some cases, if the sub-grade is good and there is no surface cracking, an overlay only is the proper fix This is the correct option if the surface is dry, brittle, and raveling In this situation, a new and additional layer of asphalt is installed over what is already there.
For thicker applications, use additional thin layers of the concrete resurfacer, or use a trowel-applied layer after the initial squeegee application For trowel-applied mixes, reduce the water to approx 2 3/4 quarts (26 liters) per 40-pound (181 kilograms) bag Refer to the bag for additional instructions and adverse temperature conditions.
Jul 07, 2014· When an asphalt contractor references an asphalt paving overlay, he is referring to the process of installing an additional layer of asphalt over an existing asphalt surface to cover imperfections Overlays are commonly applied to pavement that has minor damage like light cracking, mild deterioration, or slightly sunken areas.
Asphalt overlay is simply a faster and more streamlined process for getting a brand new, clean looking pavement surface Whether for appearance purposes or for re-fortifying the integrity of an existing lot of asphalt, utilizing an asphalt pavement overlay will strengthen.
Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher asphalt content, usually around 7-10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt This thermoplastic substance is widely used in the building industry for waterproofing.
Somewhere, an asphalt overlay is saving the day Like a beacon in the dark night of parking lot/road construction, an asphalt overlay is providing hope and a newly paved asphalt surface What is an asphalt overlay? Very simply, an asphalt overlay is a method in which an existing asphalt surface is paved over with a new asphalt cross section.
Unbonded Concrete Overlay Options Thicker concrete overlays than bonded Constructed on existing concrete, asphalt, or composite pavements Bond is NOT considered in the design Slab sizes vary depending on type of design Unbonded Concrete Resurfacing of Concrete Pavements Unbonded Concrete Resurfacing of Asphalt Pavements Unbonded Concrete.
Overlays (either structural or non-structural) make up a large portion of the roadway paving done todayThe degree of surface preparation for an overlay is dependent on the condition and type of the existing pavement Generally, the existing pavement should be structurally sound, level, clean and capable of bonding to the overlay.
Is the pavement structure (subgrade, subbase, base, and all asphalt layers) adequate to support the loads? You need to purchase our MS-23 Manual, Thickness Design of Asphalt Pavements for Heavy Wheel Loads Is the hot mix asphalt surface stiff enough to resist deformation (ruts or indentations)?.
