From page 64...
... Because Australia, New Zealand, and South Africa literally depend on chip seals to maintain large percentages of their national transportation systems is evidence that chip seal pavement preservation technology can be reliably and predictably engineered. These countries, as well as Canada, routinely impose warranties on the performance of their chip seal projects, demonstrating that chip seal contractors can construct chip seals that perform satisfactorily, and they can do so profitably without driving the price of chip seal projects to the point where hotmix asphalt overlays become economically competitive.

... A study on the life-cycle cost implications of paying the additional costs to transport high-quality aggregate is recommended to justify investing in chip seal materials, to maximize their abilities to extend pavement service life. Montana's sweep test specification, to identify the quantity of excess aggregate left on the road, shows great promise for minimizing the negative effects of loose stone on newly chip sealed roads.
