The main reason behind sealcoating asphalt is to extend the life of pavement, which is a costly investment. Whether driveways or parking lots are involved, original pavement is significant. Sealcoating is a great way to slow down the rate of pavement deterioration and improve life cycle cost.
Here are other methods in preventing weakening of asphalt and improve adherence between pavement, and various utilities that may come in contact with it.
One is cold tar, which is similar in appearance to asphalt. It is a product of bituminous coal during the production of metallurgical coke. In general, cold tar may tend to cost more than asphalt cement and protective measures should be strictly implemented as it can be hazardous to health.
Fog seal is an application of asphalt emulsion which is sprayed on the pavement, with or without sand. Fog seal is relatively cheaper kwaliteit trenbolone acetate met verzending compared to other treatments, but remains shorter in life and could be slippery and hazardous for roads.
Sand seal is an asphalt emulsion, which is applied by spray by covering a clean sand or fine aggregate. Tire rollers are usually used after the sand application and excess sand is removed from the road surface after rolling. This type of treatment provides a longer lasting life expectancy as well as provides a skid resistant surface. The fine cracks are filled and larger cracks tend to reappear within the year.
Chip seal is an application of asphalt followed by an aggregate cover. For this application, one can use an asphalt cutback, or emulsified asphalt. Aggregates would immediately be applied before the asphalt cooled down and a roller would be in affect afterwards. Once the asphalt cures, the excess is removed. More testing needs to be done in which products should be used together rocks could in fact damage vehicles.
Slurry seal is a mixture of quick setting asphalt emulsion, fine aggregate, mineral filler, additives, and water. This procedure is smoother than a chip seal treatment, yet has the same affects.
Cape seal is an application of chip seal which is then followed by slurry seal. This not only increases the life but as well binds the loose aggregate. This treatment is rarely used due to its long process and double cost.
There are various products that have both advantages and disadvantages. Weigh all the pros and cons aptly before making a decision.
