COMPUTING THE WORKING RANGE OF JOINTS AND SEALANTS
C-1. Working Range Calculations.
a. The stresses that develop in field-poured sealants and compression seals are the direct result of the
joints opening and closing as the slabs move due to temperature changes. The amount of deformation that
the seal can withstand before failure occurs is dependent upon the joint size and type of seal. The
following formulas are used in determining the joint and seal size.
b. The first step is to calculate the amount of joint opening likely to occur in the pavement using the
following equation:
