What is asphalt maintenance? Asphalt maintenance consists of defending asphalt by employing the following methods (asphalt seal coating, crack repair and asphalt repair) to prevent damage for the existing asphalt.
So why ought to a property owner have their asphalt seal coated? From the very first moment that asphalt is installed it starts a deterioration procedure. The asphalt is diminished when the binder that holds all of the aggregate (stone) collectively begins to oxide from sun light, water as well as other external circumstances. By way of the seal coating approach, the asphaltic binder is now protected from the aforementioned external circumstances. An additional benefit from asphalt seal coating is the fact that the asphalt is now protected in the damaging effects from gasoline , oil, and de-icing salts. By far the most apparent advantage from asphalt seal coating is definitely the restoration of the original colour from the asphalt. The asphalt regains that new appearance for a fraction from the original expense.
Asphalt seal coating is a approach in which coal tar emulsion or asphalt emulsion is sprayed or brushed around the asphalt surface. The seal coat material needs to be applied in two coats normally regions and 3 coats within the higher traffic places, like drive lanes.
There is much debate as to what’s the very best application approach for the seal coat material. There’s a predominant mindset amongst “old school” seal coaters that brushing the seal coat material could be the only way to go. Having said that, there are actually some brief comings from the brushing technique. By brushing the seal coat material the natural indentations on the asphalt are filled in plus the asphalt loses its traction. Also, contrary to well-known belief thicker is not superior when applying the seal coat material. The Seal coat material ought to be applied at .17 gal/sq. yd. and should never exceed .51 gal/sq. yd. total.
Using the brief comings of brushing the seal coat material becoming stated, there is a much better alternative. That alternative is spraying the seal coat material. This method makes it possible for the seal coat material to be applied evenly without filling the natural grooves of the asphalt. If a contractor states that they brush exclusively, take caution in coping with these companies. A lot of instances these companies have not invested in updated gear, that will avoid them from completing the bigger seal coating jobs.
A different aspect of seal coating that is definitely overlooked by customers may be the mixture in the seal coat material itself. The material is ought to be mixed at 25 to 35 gallons of water per 100 gallons of concentrated sealer. Also, the seal coat material really should be enhanced with 2-5 pounds of sand per every single gallon of sealer. The sand is used to restore traction to the surface following the asphalt has been treated. When producing work specifications make sure to include things like the quantity of desired sand essential per gallon of sealer. The smoother the existing surface or the greater the traffic volume will call for higher volumes of sand in the seal coat material.
Furthermore to asphalt seal coating, crack repair is important to adequately caring for asphalt. As a consequence of the settling from the ground, poor base design and asphalt oxidation asphalt will crack. When the asphalt cracks it is exposed to water damage. Water penetrates the cracks and gravity pulls it in to the sub-base (stones) which deteriorates that supportive structure. This deterioration leads to asphalt depressions, pot holes and additional cracking. Also, inside the winter when water expands inside the cracks by means of the freezing process, the cracks widen over time.
Hot tar is applied to the cracks to stop water penetration. Hot tar is melted to 375 degrees and poured into the cracks. To finish the crack repair procedure the hot tar is squeeged in to the crack to make a 4 inch band. All debris needs to be removed from the cracks before treatment. Crack repair is really a temporary fix and will not replace the have to really replace the asphalt. Even so, crack repair is considerably more cost efficient than actual asphalt replacement.
It truly is stated that if 30% or extra of asphalt is deteriorated, it is far more cost productive to replace it. With that getting mentioned, the majority of property owners decide on to replace particular sections at a time. One factor to maintain in mind is that if an area of asphalt requirements replaced mainly because it was sinking, there is certainly definitely a problem together with the sub-base and that really should be replaced too.
In the event the asphalt needs to be replaced there are two solutions for replacement. The traditional process is always to saw cut the area and replace the asphalt and seal the seams with hot tar. A different modern technique consist of utilizing a Infrared Heater to heat the existing asphalt, then more asphalt is added along with the area is compacted. The advantages of employing an Infrared heater is that the fix is often a seamless repair that can no longer allow water penetration. The main fall back with applying infared is that if there is certainly an existing sub-base problem, the asphalt will not be effectively repaired if it’s only re-heated and not basically removed to replace the underlying stone. Within the right conditions, Infrared remedies to asphalt add additional advantages for the property owner as a result of the final aspect of seamless repair.
The bottom line is the fact that property managers ought to incorporate an effective asphalt maintenance strategy into their all round preventative maintenance technique. The positive aspects of asphalt seal coating, crack repair and asphalt replacement will pay dividends in the future by way of the avoidance of expensive new asphalt. One last point, the asphalt upkeep and pavement marking sector has wide fluctuation within the top quality of contractors, so normally do your due diligence in the choice course of action.
