The site-specific climatic conditions during Crack Sealing Machine 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 which equipped with the Crack Sealing Machine 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.
Highway classification and traffic characteristics are important from two standpoints. First, highway geometrics and traffic levels may be such that overall safety during installation is greatly compromised. Applying longer lasting treatments reduces the number of subsequent applications use Crack Sealing Machine. Fewer applications means less time on the roadway and increases safety.
