It happens occasionally that an additive dosing system does not work correctly. When that happens, there is either too much or too little antistrip additive in the mixture. Its deficiency does not directly affect the quality of the mixture during production or placement. Effects may appear in the form of a lower durability of the course under traffic. However, an excess of the antistrip additive can manifest itself in an immediate and direct impact on the quality of the mixture. Usually the antistrip additive overdosage may be identified while still in the batching plant because of the characteristic (i. e., unpleasant) smell of the mixture.* The overdosed mixture distinguishes itself by having a very high workability both in the paver and under rollers, to such an extent that its further compaction is possible for up to a couple of days after placement (i. e., it is still deformable under rollers). Putting such a pavement into operation results in its rapid rutting. Another effect of increased workability of the mixture while rolling is the risk of fat spots or areas with a closed structure.
Depends on the type of adhesive agent used (mainly concerns some fatty amines).
