MATERIAL USES
5.1. Fed. Spec. and ASTM. Crack sealants conforming to Fed. Spec. SS-S-1401C, ASTM D
3405, or ASTM D 1190 can be used to seal cracks in asphalt pavements in any climatic region;
however, letter surveys of State DOTs have indicated that Fed. Spec. SS-S-1401C and ASTM D
3405 sealants generally perform better in cooler regions than do ASTM D 1190 sealants. It is
recommended that ASTM D 1190 materials not be used in areas that receive a high volume of
pedestrian traffic due to the materials' tendency to track onto the pavement and stick to the soles
of shoes.
5.2. DOT Spec. Rubberized asphalt sealants that are not covered by the above specifications
can be used only when an appropriate State DOT or local municipality material specification is
available and after the sealant has been approved by the Facilities Engineer. The DOT and local
specifications will often be modified to account for the temperature variations of the region.
Asphalt cements that contain synthetic fibers have been used successfully on a limited basis as a
crack sealant. State or municipality specifications should also be used for these materials.
5.3. Other. The crack sealant material should be tested by a government-approved independent
laboratory for specification conformance before it is used on a project. If the quantity of sealant
for the project is less than 500 pounds (227 kilograms), then the manufacturer's certificate of
compliance may be accepted in place of testing. The evaluation of local field performance data
from past sealing projects is often helpful in determining which type of sealant should be used to
seal the cracks.
