SEVEN FUNDAMENTALS FOR DURABLE SPRAYBAR WORK--JOBS YOU CAN BE PROUD OF

The following seven simple principles should be considered when putting down long-lasting asphalt seals and treatments; (1) a surface treatment will fail without a good enough foundation; (2) everyone on the job needs to have a clear mental picture of what a really top-quality surface treatment or seal coat looks like under traffic; (3) the more common faults (streaking, flushing or bleeding, loss of aggregate, and lack of bond) should be looked for and avoided; (4) carefully check the cover aggregate gradation and also watch particle flatness by specifying a maximum flakiness index; (5) determine the average least dimension since good performance is more likely with larger cover aggregate; and (7) get good adhesion. These seven steps add little if anything to the job cost and assure the quality of asphalt surface treatments and seal coats.
