The planning process centers on selecting an appropriate material and placement configuration, and determining the procedures and equipment to be used based on existing and future roadway conditions. The site-specific climatic conditions during treatment operations can occasionally influence which procedures or materials should be used. For instance, in areas where moisture or cold temperatures present scheduling problems, the use of a heat lance may expedite operations.
Overall climatic conditions must also be considered in deciding which materials and procedures are to be used. Hot climates necessitate the use of materials that will not significantly soften and track at high temperatures. Very cold climates, on the other hand, will generally require materials that retain good flexibility at low temperatures.
