EXPERT ADVICE
cracking
• Improves adhesion and cohesion properties of sealer
• Increases resistance to extreme temperatures
• Increases resistance to chemicals
• Increases color retention
• Shortens the time between coats or re-opening to traffic when a fast-drying additive is used
• Adds a degree of cost that may be offset by allowing for a greater amount of dilution
Pavement failures across the nation are visible to anyone who uses our road systems . From rutting to cracking to potholes , poor pavements aren ’ t just a nuisance , they ’ re a significant safety hazard .
Gibbs pointed out that additives to the asphalt mix such as adhesion promoters and warm-mix additives are designed to prevent the stripping of asphalt from the aggregates used in the mix , and are designed to provide protection against pavement distresses .
“ The results are safer pavements and extended road life , helping to mitigate the potentially dangerous hazards of potholes and rutting , which saves owners and agencies significant money over the lifetime of the pavement . Also , as we become more environmentally conscious , additives that help utilize a higher percentage of recycled asphalt pavement ( RAP ), are designed to reduce production and compaction temperatures , while helping the road building industry control waste , costs and energy efficiency . When roads are milled up , the ability to reuse the previous pavements on new roads is a tremendous benefit to sustaining our natural resources ,” Gibbs said .
“ Proven performance additives can be injected directly in-line with the asphalt either through blending at the asphalt terminal or in-line at the mix plant . This direct injection is an alternative to the added hassle , time , footprint , equipment , expense and safety concerns of coating the aggregates with lime dust , and eliminates additional steps in the process to ensure adequate aggregate asphalt coating and adhesion . Also , mixes that are more workable and easier to compact can drive construction costs down by reducing the equipment needed in the field .”
Asked to encapsulate the advantages of additives to pavement mixes , Gibbs named three : 1 . Extend the life of the pavement , which saves taxpayers money over the long-term . 2 . Create safer roads by preventing potential distresses that cause dangerous driving conditions for motorists . 3 . Facilitate improved mix and reduced construction costs , adding value to all stakeholders .
Additives are designed to enhance and strengthen the qualities of both asphalt mixes and sealcoating . In many respects , additives are being expected and a part of asphalt paving and maintenance today . Additives are becoming the new normal !
